Air Emergency (2003–…): Season 17, Episode 7 - Caught on Tape - full transcript

{\a2}{\c&HFFFFFF&}{\fnTahoma}say that I saw cheese plane was sinking

{\a2}{\c&HFFFFFF&}{\fnTahoma}deeper and deeper in the heart of one of

{\a2}{\c&HFFFFFF&}{\fnTahoma}Asia's busiest cities rescuers rush to

{\a2}{\c&HFFFFFF&}{\fnTahoma}pull air crash survivors to safety

{\a2}{\c&HFFFFFF&}{\fnTahoma}nothing wrong with this actuator

{\a2}{\c&HFFFFFF&}{\fnTahoma}Taiwan's Aviation Safety Council

{\a2}{\c&HFFFFFF&}{\fnTahoma}confronts emergent questions about

{\a2}{\c&HFFFFFF&}{\fnTahoma}trans-asia flight 235 what were the

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight crew doing their engineering

{\a2}{\c&HFFFFFF&}{\fnTahoma}issues involved in this event how on

{\a2}{\c&HFFFFFF&}{\fnTahoma}earth did it end up in this situation



{\a2}{\c&HFFFFFF&}{\fnTahoma}take a look at this a video surfaces

{\a2}{\c&HFFFFFF&}{\fnTahoma}that make the disaster in Taipei

{\a2}{\c&HFFFFFF&}{\fnTahoma}notorious worldwide

{\a2}{\c&HFFFFFF&}{\fnTahoma}that's quite harrowing because you're

{\a2}{\c&HFFFFFF&}{\fnTahoma}seeing the final moments of a tragic

{\a2}{\c&HFFFFFF&}{\fnTahoma}event unfolding before your eyes what

{\a2}{\c&HFFFFFF&}{\fnTahoma}was happening on that plane

{\a2}{\c&HFFFFFF&}{\fnTahoma}Taipei capital city of Taiwan near its

{\a2}{\c&HFFFFFF&}{\fnTahoma}center

{\a2}{\c&HFFFFFF&}{\fnTahoma}amid soaring towers lies Songshan

{\a2}{\c&HFFFFFF&}{\fnTahoma}Airport

{\a2}{\c&HFFFFFF&}{\fnTahoma}the next plane scheduled for departure

{\a2}{\c&HFFFFFF&}{\fnTahoma}this morning is trans-asia flight 235

{\a2}{\c&HFFFFFF&}{\fnTahoma}the trans-asia cabin crew is waiting for



{\a2}{\c&HFFFFFF&}{\fnTahoma}a last-minute addition to the passenger

{\a2}{\c&HFFFFFF&}{\fnTahoma}list

{\a2}{\c&HFFFFFF&}{\fnTahoma}welcome aboard roll knighting team it

{\a2}{\c&HFFFFFF&}{\fnTahoma}way down aisle seat dr. Leo Chow who has

{\a2}{\c&HFFFFFF&}{\fnTahoma}made it hahaha it just so happened that

{\a2}{\c&HFFFFFF&}{\fnTahoma}particular flight had a few open seats I

{\a2}{\c&HFFFFFF&}{\fnTahoma}was supposed to be on the later flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}but I decided to get on the earlier one

{\a2}{\c&HFFFFFF&}{\fnTahoma}there are three highly trained pilots in

{\a2}{\c&HFFFFFF&}{\fnTahoma}the cockpit the first officer is Leo de

{\a2}{\c&HFFFFFF&}{\fnTahoma}Jong he has almost 7,000 hours of flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}time oil pressure

{\a2}{\c&HFFFFFF&}{\fnTahoma}Jack the captain Leo chin song is a

{\a2}{\c&HFFFFFF&}{\fnTahoma}former military pilot there's also a

{\a2}{\c&HFFFFFF&}{\fnTahoma}third pilot who's an observer on today's

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}45 starter off start lights off

{\a2}{\c&HFFFFFF&}{\fnTahoma}trans-asia 2 3 5 is a commuter flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}from Taipei to the Taiwanese island of

{\a2}{\c&HFFFFFF&}{\fnTahoma}Kinmen just off the coast of mainland

{\a2}{\c&HFFFFFF&}{\fnTahoma}China scheduled flight time is

{\a2}{\c&HFFFFFF&}{\fnTahoma}approximately 1 hour would you like a

{\a2}{\c&HFFFFFF&}{\fnTahoma}paper oh thank you dr. Leo Chao hue is

{\a2}{\c&HFFFFFF&}{\fnTahoma}returning home to Kinmen where he runs a

{\a2}{\c&HFFFFFF&}{\fnTahoma}medical practice Hong sang-soo fan saw I

{\a2}{\c&HFFFFFF&}{\fnTahoma}usually took trans-asia because their

{\a2}{\c&HFFFFFF&}{\fnTahoma}service was quite good but you had time

{\a2}{\c&HFFFFFF&}{\fnTahoma}have full habit or a squad when I'd get

{\a2}{\c&HFFFFFF&}{\fnTahoma}on the plane I'd like to grab a paper

{\a2}{\c&HFFFFFF&}{\fnTahoma}and catch up on the day's events g'way

{\a2}{\c&HFFFFFF&}{\fnTahoma}the cabins ready sir okay Roger thanks

{\a2}{\c&HFFFFFF&}{\fnTahoma}sunshine ground trans-asia 2 3 5

{\a2}{\c&HFFFFFF&}{\fnTahoma}translator 2 3 5 runway 1-0 tactic a

{\a2}{\c&HFFFFFF&}{\fnTahoma}whiff game okay

{\a2}{\c&HFFFFFF&}{\fnTahoma}the atr-72 600 is the latest most

{\a2}{\c&HFFFFFF&}{\fnTahoma}advanced version of the European

{\a2}{\c&HFFFFFF&}{\fnTahoma}commuter plane its pratt & whitney

{\a2}{\c&HFFFFFF&}{\fnTahoma}turboprop engines are extremely powerful

{\a2}{\c&HFFFFFF&}{\fnTahoma}and fuel-efficient it's a very popular

{\a2}{\c&HFFFFFF&}{\fnTahoma}aircraft particularly because it has

{\a2}{\c&HFFFFFF&}{\fnTahoma}attractive operating economics it's

{\a2}{\c&HFFFFFF&}{\fnTahoma}commonly used in short haul regional

{\a2}{\c&HFFFFFF&}{\fnTahoma}airline operations

{\a2}{\c&HFFFFFF&}{\fnTahoma}the pilots digital displays create

{\a2}{\c&HFFFFFF&}{\fnTahoma}what's known as a glass cockpit when

{\a2}{\c&HFFFFFF&}{\fnTahoma}people refer to a glass cockpit aircraft

{\a2}{\c&HFFFFFF&}{\fnTahoma}they're referring to not only the

{\a2}{\c&HFFFFFF&}{\fnTahoma}displays but what often we're talking

{\a2}{\c&HFFFFFF&}{\fnTahoma}about is an advanced technology aircraft

{\a2}{\c&HFFFFFF&}{\fnTahoma}with sophisticated automation

{\a2}{\c&HFFFFFF&}{\fnTahoma}capabilities the electronic checklists

{\a2}{\c&HFFFFFF&}{\fnTahoma}switch automatically once you complete

{\a2}{\c&HFFFFFF&}{\fnTahoma}certain parts it'll switch forward the

{\a2}{\c&HFFFFFF&}{\fnTahoma}first officer briefs his colleague on

{\a2}{\c&HFFFFFF&}{\fnTahoma}the cockpits technology pumping chilling

{\a2}{\c&HFFFFFF&}{\fnTahoma}is an experienced pilot who's learning

{\a2}{\c&HFFFFFF&}{\fnTahoma}this computerized system can you do

{\a2}{\c&HFFFFFF&}{\fnTahoma}manually what you can but when starting

{\a2}{\c&HFFFFFF&}{\fnTahoma}the engine for example it'll go to the

{\a2}{\c&HFFFFFF&}{\fnTahoma}next page once you close the bleep

{\a2}{\c&HFFFFFF&}{\fnTahoma}valves

{\a2}{\c&HFFFFFF&}{\fnTahoma}Songshan Airport sees six million

{\a2}{\c&HFFFFFF&}{\fnTahoma}passengers a year for air traffic

{\a2}{\c&HFFFFFF&}{\fnTahoma}controllers that means handling about a

{\a2}{\c&HFFFFFF&}{\fnTahoma}hundred flights a day translator 235

{\a2}{\c&HFFFFFF&}{\fnTahoma}runway one zero wind one zero zero

{\a2}{\c&HFFFFFF&}{\fnTahoma}Degree Niner knots cleared for takeoff

{\a2}{\c&HFFFFFF&}{\fnTahoma}cabin crew prepare for takeoff

{\a2}{\c&HFFFFFF&}{\fnTahoma}the quakes right thank you enjoy your

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}just before 11:00 in the morning flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}2:35 gets rolling engine instrument

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain engages the autopilot and

{\a2}{\c&HFFFFFF&}{\fnTahoma}sets his desired airspeed and altitude

{\a2}{\c&HFFFFFF&}{\fnTahoma}as soon as the aircraft has taken off

{\a2}{\c&HFFFFFF&}{\fnTahoma}they're going through a series of

{\a2}{\c&HFFFFFF&}{\fnTahoma}checklist items Europe Europe I know

{\a2}{\c&HFFFFFF&}{\fnTahoma}they've got a particular client profile

{\a2}{\c&HFFFFFF&}{\fnTahoma}and they're executing the the after

{\a2}{\c&HFFFFFF&}{\fnTahoma}takeoff checks and the initial climb

{\a2}{\c&HFFFFFF&}{\fnTahoma}checks you to make sure that all the

{\a2}{\c&HFFFFFF&}{\fnTahoma}systems are performing as required

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight 235 climbs out over metropolitan

{\a2}{\c&HFFFFFF&}{\fnTahoma}Taipei

{\a2}{\c&HFFFFFF&}{\fnTahoma}a densely packed city of more than seven

{\a2}{\c&HFFFFFF&}{\fnTahoma}million people

{\a2}{\c&HFFFFFF&}{\fnTahoma}seconds later the master warning sounds

{\a2}{\c&HFFFFFF&}{\fnTahoma}the master warning is indicative of an

{\a2}{\c&HFFFFFF&}{\fnTahoma}emergency situation requiring an

{\a2}{\c&HFFFFFF&}{\fnTahoma}immediate response trans-asia 2:35 has

{\a2}{\c&HFFFFFF&}{\fnTahoma}lost an engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain disengages the autopilot I

{\a2}{\c&HFFFFFF&}{\fnTahoma}have control you have control in the

{\a2}{\c&HFFFFFF&}{\fnTahoma}cabin engine noise suddenly drops

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}the pilots need to get their plane back

{\a2}{\c&HFFFFFF&}{\fnTahoma}on the ground

{\a2}{\c&HFFFFFF&}{\fnTahoma}heading mode the captain wants a heading

{\a2}{\c&HFFFFFF&}{\fnTahoma}back to the airport the below 2,500 feet

{\a2}{\c&HFFFFFF&}{\fnTahoma}turn to heading it's come on

{\a2}{\c&HFFFFFF&}{\fnTahoma}zero zero Niner five check when you lose

{\a2}{\c&HFFFFFF&}{\fnTahoma}an engine in a twin-engine aircraft you

{\a2}{\c&HFFFFFF&}{\fnTahoma}need to be able to maintain your climb

{\a2}{\c&HFFFFFF&}{\fnTahoma}performance and you need to be very

{\a2}{\c&HFFFFFF&}{\fnTahoma}careful that your airspeed does not

{\a2}{\c&HFFFFFF&}{\fnTahoma}decay or reduce too much during that

{\a2}{\c&HFFFFFF&}{\fnTahoma}climb in flame out check check

{\a2}{\c&HFFFFFF&}{\fnTahoma}speed and climb rate are dropping fast

{\a2}{\c&HFFFFFF&}{\fnTahoma}but the speed

{\a2}{\c&HFFFFFF&}{\fnTahoma}the stall warning means the plane is

{\a2}{\c&HFFFFFF&}{\fnTahoma}flying too slowly to maintain lift stall

{\a2}{\c&HFFFFFF&}{\fnTahoma}warning at low altitudes a critical

{\a2}{\c&HFFFFFF&}{\fnTahoma}situation that no pilot ever wants to

{\a2}{\c&HFFFFFF&}{\fnTahoma}end up in flight 235 is less than a mile

{\a2}{\c&HFFFFFF&}{\fnTahoma}from the runway

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}passengers can now see that they're no

{\a2}{\c&HFFFFFF&}{\fnTahoma}longer climbing

{\a2}{\c&HFFFFFF&}{\fnTahoma}train ahead

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}the stick shaker is a tactile alerting

{\a2}{\c&HFFFFFF&}{\fnTahoma}system where the control column shakes

{\a2}{\c&HFFFFFF&}{\fnTahoma}or vibrates very noticeably it's a very

{\a2}{\c&HFFFFFF&}{\fnTahoma}salient tube to pilots to indicate that

{\a2}{\c&HFFFFFF&}{\fnTahoma}you must intervene to prevent the

{\a2}{\c&HFFFFFF&}{\fnTahoma}aircraft from entering a store

{\a2}{\c&HFFFFFF&}{\fnTahoma}the situation is critical what's a

{\a2}{\c&HFFFFFF&}{\fnTahoma}highly stressful event Mayday Mayday

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine flameout Songshan controllers

{\a2}{\c&HFFFFFF&}{\fnTahoma}fear the worst a crash in the middle of

{\a2}{\c&HFFFFFF&}{\fnTahoma}the city

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine flameout both sides how is this

{\a2}{\c&HFFFFFF&}{\fnTahoma}possible

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight 235 is now only 500 feet above

{\a2}{\c&HFFFFFF&}{\fnTahoma}the streets of Taipei

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}the crew was surrounded by high-density

{\a2}{\c&HFFFFFF&}{\fnTahoma}housing high-rise apartment blocks a

{\a2}{\c&HFFFFFF&}{\fnTahoma}heavily populated area - really between

{\a2}{\c&HFFFFFF&}{\fnTahoma}a rock and a hard place

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}all controllers can see is that flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}235 has dropped off the radar

{\a2}{\c&HFFFFFF&}{\fnTahoma}they have no idea if anyone has survived

{\a2}{\c&HFFFFFF&}{\fnTahoma}spend all takeoff and landing operations

{\a2}{\c&HFFFFFF&}{\fnTahoma}begin emergency procedures

{\a2}{\c&HFFFFFF&}{\fnTahoma}after hitting an elevated highway in

{\a2}{\c&HFFFFFF&}{\fnTahoma}downtown Taipei trans-asia flight 235 is

{\a2}{\c&HFFFFFF&}{\fnTahoma}sinking in the Keelung River

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}don't worry God kid said that's good if

{\a2}{\c&HFFFFFF&}{\fnTahoma}I could feel something was off

{\a2}{\c&HFFFFFF&}{\fnTahoma}I thought to myself why is there water

{\a2}{\c&HFFFFFF&}{\fnTahoma}where my shoes are on USC

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}those lucky enough to survive the crash

{\a2}{\c&HFFFFFF&}{\fnTahoma}are now at risk of drowning

{\a2}{\c&HFFFFFF&}{\fnTahoma}yeah well hide see that potential I

{\a2}{\c&HFFFFFF&}{\fnTahoma}remember very clearly me and a nigga I

{\a2}{\c&HFFFFFF&}{\fnTahoma}saw a woman who I thought was an air

{\a2}{\c&HFFFFFF&}{\fnTahoma}hostess without the out path I told her

{\a2}{\c&HFFFFFF&}{\fnTahoma}not to be afraid okay

{\a2}{\c&HFFFFFF&}{\fnTahoma}the water level starts to rise

{\a2}{\c&HFFFFFF&}{\fnTahoma}so hey that got so cheesy ate the plane

{\a2}{\c&HFFFFFF&}{\fnTahoma}was sinking deeper and deeper ID had

{\a2}{\c&HFFFFFF&}{\fnTahoma}that Dante was the temperature was very

{\a2}{\c&HFFFFFF&}{\fnTahoma}cold I couldn't hear anything

{\a2}{\c&HFFFFFF&}{\fnTahoma}team without singing the water had

{\a2}{\c&HFFFFFF&}{\fnTahoma}drowned out all sounds awesome that yet

{\a2}{\c&HFFFFFF&}{\fnTahoma}young

{\a2}{\c&HFFFFFF&}{\fnTahoma}then passengers are relieved to hear a

{\a2}{\c&HFFFFFF&}{\fnTahoma}welcome sound

{\a2}{\c&HFFFFFF&}{\fnTahoma}rescuers are on the way

{\a2}{\c&HFFFFFF&}{\fnTahoma}first responders climb onto the fuselage

{\a2}{\c&HFFFFFF&}{\fnTahoma}and start pulling people from the

{\a2}{\c&HFFFFFF&}{\fnTahoma}wreckage

{\a2}{\c&HFFFFFF&}{\fnTahoma}she won't I just wanted the doors to

{\a2}{\c&HFFFFFF&}{\fnTahoma}open quickly so that I could escape okay

{\a2}{\c&HFFFFFF&}{\fnTahoma}the swift current of the Keelung River

{\a2}{\c&HFFFFFF&}{\fnTahoma}means that shocked survivors won't be

{\a2}{\c&HFFFFFF&}{\fnTahoma}safe until rescuers can get them to the

{\a2}{\c&HFFFFFF&}{\fnTahoma}riverbank

{\a2}{\c&HFFFFFF&}{\fnTahoma}the city of Taipei has never seen an

{\a2}{\c&HFFFFFF&}{\fnTahoma}aviation accident like it of the 58

{\a2}{\c&HFFFFFF&}{\fnTahoma}people on flight 235 only 15 make it out

{\a2}{\c&HFFFFFF&}{\fnTahoma}alive

{\a2}{\c&HFFFFFF&}{\fnTahoma}all three pilots are dead

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators from Taiwan's Aviation

{\a2}{\c&HFFFFFF&}{\fnTahoma}Safety Council are anxious to start

{\a2}{\c&HFFFFFF&}{\fnTahoma}collecting evidence at the scene both

{\a2}{\c&HFFFFFF&}{\fnTahoma}occur hey who it's another seeker but

{\a2}{\c&HFFFFFF&}{\fnTahoma}the most important thing for us is to

{\a2}{\c&HFFFFFF&}{\fnTahoma}retrieve the black box reserved now here

{\a2}{\c&HFFFFFF&}{\fnTahoma}is the house however we have to wait for

{\a2}{\c&HFFFFFF&}{\fnTahoma}the search and rescue to finish before

{\a2}{\c&HFFFFFF&}{\fnTahoma}we can go in that universe secure go

{\a2}{\c&HFFFFFF&}{\fnTahoma}join you until home for now they have to

{\a2}{\c&HFFFFFF&}{\fnTahoma}be patient but a stunning piece of

{\a2}{\c&HFFFFFF&}{\fnTahoma}evidence has already surfaced take a

{\a2}{\c&HFFFFFF&}{\fnTahoma}look at this just came in

{\a2}{\c&HFFFFFF&}{\fnTahoma}and put it up here for me

{\a2}{\c&HFFFFFF&}{\fnTahoma}what was happening on that plane play it

{\a2}{\c&HFFFFFF&}{\fnTahoma}again

{\a2}{\c&HFFFFFF&}{\fnTahoma}it was quite extraordinary that the

{\a2}{\c&HFFFFFF&}{\fnTahoma}final sequence of events was captured by

{\a2}{\c&HFFFFFF&}{\fnTahoma}the the dashcam footage in the motor

{\a2}{\c&HFFFFFF&}{\fnTahoma}vehicle but it's quite harrowing because

{\a2}{\c&HFFFFFF&}{\fnTahoma}you're seeing the final moments of a

{\a2}{\c&HFFFFFF&}{\fnTahoma}tragic event unfolding before your eyes

{\a2}{\c&HFFFFFF&}{\fnTahoma}visit visit now Donilon Judah and

{\a2}{\c&HFFFFFF&}{\fnTahoma}Jacques we were obviously really shocked

{\a2}{\c&HFFFFFF&}{\fnTahoma}wondering why the plane was flying in

{\a2}{\c&HFFFFFF&}{\fnTahoma}this way well what do you think left

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine control surfaces we watched the

{\a2}{\c&HFFFFFF&}{\fnTahoma}video clip we know there's something

{\a2}{\c&HFFFFFF&}{\fnTahoma}wrong about the engine the prop seems

{\a2}{\c&HFFFFFF&}{\fnTahoma}very slow you can see the propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}blades they could have been going at

{\a2}{\c&HFFFFFF&}{\fnTahoma}full speed I thought either the aircraft

{\a2}{\c&HFFFFFF&}{\fnTahoma}lost one engine or either the flap or a

{\a2}{\c&HFFFFFF&}{\fnTahoma}L'Orange jam during takeoff we need to

{\a2}{\c&HFFFFFF&}{\fnTahoma}study that wreckage

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}salvage crews pull what remains of

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight 235 from the Keelung River we

{\a2}{\c&HFFFFFF&}{\fnTahoma}recover everything I think and finish

{\a2}{\c&HFFFFFF&}{\fnTahoma}the wreckage recovery run noontime the

{\a2}{\c&HFFFFFF&}{\fnTahoma}second day

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}there's no telling which piece of

{\a2}{\c&HFFFFFF&}{\fnTahoma}wreckage might hold an important clue

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators wonder if the flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}control system shows any sign of a

{\a2}{\c&HFFFFFF&}{\fnTahoma}malfunction so we have to exam that part

{\a2}{\c&HFFFFFF&}{\fnTahoma}of the wreckage nothing wrong with this

{\a2}{\c&HFFFFFF&}{\fnTahoma}actuator we cannot find anything wrong

{\a2}{\c&HFFFFFF&}{\fnTahoma}with the actuator the linkage of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}control we cannot find any normal

{\a2}{\c&HFFFFFF&}{\fnTahoma}situation for the flight control system

{\a2}{\c&HFFFFFF&}{\fnTahoma}control system seems fine a search for

{\a2}{\c&HFFFFFF&}{\fnTahoma}any pre-impact failures in the plane's

{\a2}{\c&HFFFFFF&}{\fnTahoma}hydraulic system also comes up empty

{\a2}{\c&HFFFFFF&}{\fnTahoma}nothing wrong with the hydraulics this

{\a2}{\c&HFFFFFF&}{\fnTahoma}is the left engine yes

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators know from the dashcam

{\a2}{\c&HFFFFFF&}{\fnTahoma}video that the plane was banked steeply

{\a2}{\c&HFFFFFF&}{\fnTahoma}to the left a mechanical fault with the

{\a2}{\c&HFFFFFF&}{\fnTahoma}left engine seems like the next most

{\a2}{\c&HFFFFFF&}{\fnTahoma}obvious suspect we need to take a look

{\a2}{\c&HFFFFFF&}{\fnTahoma}inside

{\a2}{\c&HFFFFFF&}{\fnTahoma}get the borstal what would you nuts it

{\a2}{\c&HFFFFFF&}{\fnTahoma}in Khandala to get parts from a

{\a2}{\c&HFFFFFF&}{\fnTahoma}borescope examination we can see whether

{\a2}{\c&HFFFFFF&}{\fnTahoma}or not the compressor and turbine are

{\a2}{\c&HFFFFFF&}{\fnTahoma}damaged on inside admissible social

{\a2}{\c&HFFFFFF&}{\fnTahoma}Yacouba since the turbine rotates with

{\a2}{\c&HFFFFFF&}{\fnTahoma}extremely high speed if it is even

{\a2}{\c&HFFFFFF&}{\fnTahoma}slightly damaged it will be completely

{\a2}{\c&HFFFFFF&}{\fnTahoma}destroyed but the borescope examination

{\a2}{\c&HFFFFFF&}{\fnTahoma}yields no new clues

{\a2}{\c&HFFFFFF&}{\fnTahoma}not since half eyes in the examination

{\a2}{\c&HFFFFFF&}{\fnTahoma}showed that everything was in place and

{\a2}{\c&HFFFFFF&}{\fnTahoma}all the moving parts were still capable

{\a2}{\c&HFFFFFF&}{\fnTahoma}of moving left engine completely

{\a2}{\c&HFFFFFF&}{\fnTahoma}operational strange they need to explore

{\a2}{\c&HFFFFFF&}{\fnTahoma}other possibilities what about the right

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine it's particular they study the

{\a2}{\c&HFFFFFF&}{\fnTahoma}right engine and what they find is

{\a2}{\c&HFFFFFF&}{\fnTahoma}mystifying look at the blades they're

{\a2}{\c&HFFFFFF&}{\fnTahoma}feathered feathered is a propellers

{\a2}{\c&HFFFFFF&}{\fnTahoma}failsafe position when a propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine loses power in flight the blades

{\a2}{\c&HFFFFFF&}{\fnTahoma}automatically rotate parallel to the

{\a2}{\c&HFFFFFF&}{\fnTahoma}Airstream to reduce drag what an auto

{\a2}{\c&HFFFFFF&}{\fnTahoma}feather does it changes the pitch of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}blades to reduce the drag on the blades

{\a2}{\c&HFFFFFF&}{\fnTahoma}to make sure that the airplanes fine

{\a2}{\c&HFFFFFF&}{\fnTahoma}performance is not degraded the

{\a2}{\c&HFFFFFF&}{\fnTahoma}discovery only deepens the mystery why

{\a2}{\c&HFFFFFF&}{\fnTahoma}would the right engine be feathered when

{\a2}{\c&HFFFFFF&}{\fnTahoma}the dashcam video clearly shows the

{\a2}{\c&HFFFFFF&}{\fnTahoma}plane banking to the left it doesn't

{\a2}{\c&HFFFFFF&}{\fnTahoma}make any sense let's have a look

{\a2}{\c&HFFFFFF&}{\fnTahoma}when we discover a feather of the favela

{\a2}{\c&HFFFFFF&}{\fnTahoma}we know there should be something wrong

{\a2}{\c&HFFFFFF&}{\fnTahoma}about engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}anything nothing at all

{\a2}{\c&HFFFFFF&}{\fnTahoma}kiss edema pathology cotton both engines

{\a2}{\c&HFFFFFF&}{\fnTahoma}yielded normal results after examination

{\a2}{\c&HFFFFFF&}{\fnTahoma}they were both fine there's nothing

{\a2}{\c&HFFFFFF&}{\fnTahoma}wrong with this engine either

{\a2}{\c&HFFFFFF&}{\fnTahoma}if both engines were operational why did

{\a2}{\c&HFFFFFF&}{\fnTahoma}this plane crash investigators now have

{\a2}{\c&HFFFFFF&}{\fnTahoma}two related questions to answer

{\a2}{\c&HFFFFFF&}{\fnTahoma}what caused the right engines propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}to feather train and why did the plane

{\a2}{\c&HFFFFFF&}{\fnTahoma}Bank violently to the left just before

{\a2}{\c&HFFFFFF&}{\fnTahoma}impact

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}at a Songshan Airport hangar Taiwanese

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators still have no explanation

{\a2}{\c&HFFFFFF&}{\fnTahoma}for the crash of trans-asia flight 235

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}video of the turboprops fatal plunge

{\a2}{\c&HFFFFFF&}{\fnTahoma}into the Keelung River has spread

{\a2}{\c&HFFFFFF&}{\fnTahoma}worldwide but clues to what caused the

{\a2}{\c&HFFFFFF&}{\fnTahoma}crash are in short supply

{\a2}{\c&HFFFFFF&}{\fnTahoma}hello okay thank you sir

{\a2}{\c&HFFFFFF&}{\fnTahoma}FDR date is in all right let's have a

{\a2}{\c&HFFFFFF&}{\fnTahoma}look

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators hope the planes flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}data recorder can tell them more

{\a2}{\c&HFFFFFF&}{\fnTahoma}the FDR records dozens of performance

{\a2}{\c&HFFFFFF&}{\fnTahoma}parameters including fuel flow engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}temperature and propeller speed okay

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine flameout check check

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators already know that the

{\a2}{\c&HFFFFFF&}{\fnTahoma}right-side propeller feather before

{\a2}{\c&HFFFFFF&}{\fnTahoma}impact watch the speed

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}let's see the operating systems of

{\a2}{\c&HFFFFFF&}{\fnTahoma}Engine 2 perhaps the flight data can

{\a2}{\c&HFFFFFF&}{\fnTahoma}tell them why when we go through the

{\a2}{\c&HFFFFFF&}{\fnTahoma}data for engine number two we find some

{\a2}{\c&HFFFFFF&}{\fnTahoma}parameters or normal like oil pressure

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine temperature fuel flow engines

{\a2}{\c&HFFFFFF&}{\fnTahoma}completely fine but one other piece of

{\a2}{\c&HFFFFFF&}{\fnTahoma}data seems to tell a different story

{\a2}{\c&HFFFFFF&}{\fnTahoma}take a look at this the torque is all

{\a2}{\c&HFFFFFF&}{\fnTahoma}over the place one parameter the torque

{\a2}{\c&HFFFFFF&}{\fnTahoma}value for a torque is a measure of an

{\a2}{\c&HFFFFFF&}{\fnTahoma}engines power to spin the propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}it increases and decreases during flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}but it's not supposed to fluctuate why

{\a2}{\c&HFFFFFF&}{\fnTahoma}is it over that's me the schematic they

{\a2}{\c&HFFFFFF&}{\fnTahoma}dig deeper studying how the pratt &

{\a2}{\c&HFFFFFF&}{\fnTahoma}whitney engine measures torque so we try

{\a2}{\c&HFFFFFF&}{\fnTahoma}to find out the design logic for a

{\a2}{\c&HFFFFFF&}{\fnTahoma}persistent what's the connection between

{\a2}{\c&HFFFFFF&}{\fnTahoma}the torque and a feather propellers they

{\a2}{\c&HFFFFFF&}{\fnTahoma}learned that the engines auto feathering

{\a2}{\c&HFFFFFF&}{\fnTahoma}system includes an electronic torque

{\a2}{\c&HFFFFFF&}{\fnTahoma}sensor it measures how much twisting

{\a2}{\c&HFFFFFF&}{\fnTahoma}force the engine is producing extremely

{\a2}{\c&HFFFFFF&}{\fnTahoma}low torque indicates that the engine has

{\a2}{\c&HFFFFFF&}{\fnTahoma}failed so a low reading triggers the

{\a2}{\c&HFFFFFF&}{\fnTahoma}system to feather the propeller but they

{\a2}{\c&HFFFFFF&}{\fnTahoma}know the engine did not fail there seems

{\a2}{\c&HFFFFFF&}{\fnTahoma}to be only one way to explain the

{\a2}{\c&HFFFFFF&}{\fnTahoma}unusual talk data maybe the sensor is

{\a2}{\c&HFFFFFF&}{\fnTahoma}sending a faulty reading triggering the

{\a2}{\c&HFFFFFF&}{\fnTahoma}auto feathering unit they suspect the

{\a2}{\c&HFFFFFF&}{\fnTahoma}problem was not with the engine itself

{\a2}{\c&HFFFFFF&}{\fnTahoma}but with the sensor measuring torque we

{\a2}{\c&HFFFFFF&}{\fnTahoma}figure out that that probably will be

{\a2}{\c&HFFFFFF&}{\fnTahoma}the signal problem between torque sensor

{\a2}{\c&HFFFFFF&}{\fnTahoma}and the receiver said the sensor to the

{\a2}{\c&HFFFFFF&}{\fnTahoma}lab so we can analyze it if they're

{\a2}{\c&HFFFFFF&}{\fnTahoma}right about the torque sensor failing

{\a2}{\c&HFFFFFF&}{\fnTahoma}then they'll finally have solved the

{\a2}{\c&HFFFFFF&}{\fnTahoma}mystery of the feathered propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}but investigators are no closer to

{\a2}{\c&HFFFFFF&}{\fnTahoma}understanding another mysterious aspect

{\a2}{\c&HFFFFFF&}{\fnTahoma}of this crash why did a two engine plane

{\a2}{\c&HFFFFFF&}{\fnTahoma}with a feathered propeller on the right

{\a2}{\c&HFFFFFF&}{\fnTahoma}side end up banking to the left

{\a2}{\c&HFFFFFF&}{\fnTahoma}searching for an answer they returned to

{\a2}{\c&HFFFFFF&}{\fnTahoma}the flight data what are the parameters

{\a2}{\c&HFFFFFF&}{\fnTahoma}of the left engine sir can you show me

{\a2}{\c&HFFFFFF&}{\fnTahoma}the fuel flow please that all seems fine

{\a2}{\c&HFFFFFF&}{\fnTahoma}Belair speed according to the data the

{\a2}{\c&HFFFFFF&}{\fnTahoma}left engine was in perfect working order

{\a2}{\c&HFFFFFF&}{\fnTahoma}how in contention number ones

{\a2}{\c&HFFFFFF&}{\fnTahoma}performance was always good all its

{\a2}{\c&HFFFFFF&}{\fnTahoma}statistics were normal windy but when

{\a2}{\c&HFFFFFF&}{\fnTahoma}they check the throttle settings they

{\a2}{\c&HFFFFFF&}{\fnTahoma}make a stunning discovery unbelievable

{\a2}{\c&HFFFFFF&}{\fnTahoma}when we go through the FBI data we find

{\a2}{\c&HFFFFFF&}{\fnTahoma}that the power of the number one engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}was gradually being reduced reduced and

{\a2}{\c&HFFFFFF&}{\fnTahoma}eventually be shut off the left engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}was manually shut down

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators know the atr-72 is not

{\a2}{\c&HFFFFFF&}{\fnTahoma}equipped with an auto throttle system

{\a2}{\c&HFFFFFF&}{\fnTahoma}the throttles can only be moved by hand

{\a2}{\c&HFFFFFF&}{\fnTahoma}that have been shut down by one of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}pilots so we start to wondering why the

{\a2}{\c&HFFFFFF&}{\fnTahoma}pilot was shot on the good engine say

{\a2}{\c&HFFFFFF&}{\fnTahoma}girls Holocaust anemia honestly at the

{\a2}{\c&HFFFFFF&}{\fnTahoma}beginning we did not understand how this

{\a2}{\c&HFFFFFF&}{\fnTahoma}can happen to know the wisdom or

{\a2}{\c&HFFFFFF&}{\fnTahoma}volunteer shit she that's crazy

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}let's take a look the circuit board

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators examine the torque sensor

{\a2}{\c&HFFFFFF&}{\fnTahoma}from the right engine of trans-asia

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight 235 they're looking for any

{\a2}{\c&HFFFFFF&}{\fnTahoma}defect that could have caused the

{\a2}{\c&HFFFFFF&}{\fnTahoma}propeller to feather in flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}Detroit has the old digger the lab used

{\a2}{\c&HFFFFFF&}{\fnTahoma}precise testing methods they made a

{\a2}{\c&HFFFFFF&}{\fnTahoma}cross-section of the circuit board and

{\a2}{\c&HFFFFFF&}{\fnTahoma}looked at its image confounded teenisha

{\a2}{\c&HFFFFFF&}{\fnTahoma}take a look at this it's broken soda

{\a2}{\c&HFFFFFF&}{\fnTahoma}they discover microscopic faults in the

{\a2}{\c&HFFFFFF&}{\fnTahoma}circuit board and that was related to

{\a2}{\c&HFFFFFF&}{\fnTahoma}the soldering joints in in a particular

{\a2}{\c&HFFFFFF&}{\fnTahoma}circuit board being compromised for

{\a2}{\c&HFFFFFF&}{\fnTahoma}reasons that were difficult to establish

{\a2}{\c&HFFFFFF&}{\fnTahoma}that was possibly related to some form

{\a2}{\c&HFFFFFF&}{\fnTahoma}of manufacturing defect or something of

{\a2}{\c&HFFFFFF&}{\fnTahoma}that nature

{\a2}{\c&HFFFFFF&}{\fnTahoma}and that there will be enough to start

{\a2}{\c&HFFFFFF&}{\fnTahoma}the transmission of the signal with a

{\a2}{\c&HFFFFFF&}{\fnTahoma}broken circuit board the torque sensor

{\a2}{\c&HFFFFFF&}{\fnTahoma}couldn't do its job even though the

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine was turning the sensor couldn't

{\a2}{\c&HFFFFFF&}{\fnTahoma}detect any talk so the system

{\a2}{\c&HFFFFFF&}{\fnTahoma}automatically feathered the propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}the brain of the system thought that

{\a2}{\c&HFFFFFF&}{\fnTahoma}talk had reduced below a predetermined

{\a2}{\c&HFFFFFF&}{\fnTahoma}value which I think it's about eighteen

{\a2}{\c&HFFFFFF&}{\fnTahoma}percent and that is what triggered the

{\a2}{\c&HFFFFFF&}{\fnTahoma}auto feather

{\a2}{\c&HFFFFFF&}{\fnTahoma}okay engine flameout check check

{\a2}{\c&HFFFFFF&}{\fnTahoma}finally they understand why the

{\a2}{\c&HFFFFFF&}{\fnTahoma}right-side propeller feathered but they

{\a2}{\c&HFFFFFF&}{\fnTahoma}still haven't explained the crash the

{\a2}{\c&HFFFFFF&}{\fnTahoma}atr-72 has two engines losing propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}thrust in one of them should not have

{\a2}{\c&HFFFFFF&}{\fnTahoma}been a catastrophic event

{\a2}{\c&HFFFFFF&}{\fnTahoma}that design to fly only with one engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}pilots trained fringe and out operations

{\a2}{\c&HFFFFFF&}{\fnTahoma}regularly typically its bread and butter

{\a2}{\c&HFFFFFF&}{\fnTahoma}for an airline pilot to deal with an

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine failure on a multi-engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}aircraft to figure out why 43 people

{\a2}{\c&HFFFFFF&}{\fnTahoma}died investigators must now answer a

{\a2}{\c&HFFFFFF&}{\fnTahoma}much more difficult question we still

{\a2}{\c&HFFFFFF&}{\fnTahoma}have number one engine produce power

{\a2}{\c&HFFFFFF&}{\fnTahoma}normally but for some reason the pilot

{\a2}{\c&HFFFFFF&}{\fnTahoma}decided to shut down the code engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}watch the speed

{\a2}{\c&HFFFFFF&}{\fnTahoma}we had to find out why

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators turn to the cockpit voice

{\a2}{\c&HFFFFFF&}{\fnTahoma}recording okay ready

{\a2}{\c&HFFFFFF&}{\fnTahoma}let's see what we got check the accident

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight is very short less than three

{\a2}{\c&HFFFFFF&}{\fnTahoma}minutes so we listen to the CVR starting

{\a2}{\c&HFFFFFF&}{\fnTahoma}from the takeoff roll to the end of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight for taxi checklist propeller

{\a2}{\c&HFFFFFF&}{\fnTahoma}brake off nose wheel steering Oh

{\a2}{\c&HFFFFFF&}{\fnTahoma}procedure complete checklist complete

{\a2}{\c&HFFFFFF&}{\fnTahoma}so far the following procedure to a tee

{\a2}{\c&HFFFFFF&}{\fnTahoma}you have to make your procedure very

{\a2}{\c&HFFFFFF&}{\fnTahoma}clear well let's see what happens closer

{\a2}{\c&HFFFFFF&}{\fnTahoma}to take off engine instrument

{\a2}{\c&HFFFFFF&}{\fnTahoma}v1 v1 rotate

{\a2}{\c&HFFFFFF&}{\fnTahoma}what's that sound

{\a2}{\c&HFFFFFF&}{\fnTahoma}must be the engine to fault warning when

{\a2}{\c&HFFFFFF&}{\fnTahoma}the master warning first activated they

{\a2}{\c&HFFFFFF&}{\fnTahoma}are approximately about 1,200 feet above

{\a2}{\c&HFFFFFF&}{\fnTahoma}ground level they're flying atr-72 600

{\a2}{\c&HFFFFFF&}{\fnTahoma}it shouldn't be a huge problem

{\a2}{\c&HFFFFFF&}{\fnTahoma}if they follow the procedure do

{\a2}{\c&HFFFFFF&}{\fnTahoma}everything correctly they should be able

{\a2}{\c&HFFFFFF&}{\fnTahoma}to fly back to land without any problem

{\a2}{\c&HFFFFFF&}{\fnTahoma}this is a crucial moment let's hear what

{\a2}{\c&HFFFFFF&}{\fnTahoma}they're gonna do next I have control

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators hear the sound of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}autopilot turning off is disengaging the

{\a2}{\c&HFFFFFF&}{\fnTahoma}autopilot he shouldn't be doing that

{\a2}{\c&HFFFFFF&}{\fnTahoma}it's hard to understand why the pilot

{\a2}{\c&HFFFFFF&}{\fnTahoma}flying disconnected the autopilot during

{\a2}{\c&HFFFFFF&}{\fnTahoma}an emergency situation he just made a

{\a2}{\c&HFFFFFF&}{\fnTahoma}difficult situation worse

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}keep playing okay

{\a2}{\c&HFFFFFF&}{\fnTahoma}- Jen flameout check check their

{\a2}{\c&HFFFFFF&}{\fnTahoma}attention will be directed to the engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}warning display which in the atr-72

{\a2}{\c&HFFFFFF&}{\fnTahoma}clearly indicates which engine has

{\a2}{\c&HFFFFFF&}{\fnTahoma}failed

{\a2}{\c&HFFFFFF&}{\fnTahoma}there's a checklist procedure on the

{\a2}{\c&HFFFFFF&}{\fnTahoma}screen you follow it step by step

{\a2}{\c&HFFFFFF&}{\fnTahoma}but instead of following the emergency

{\a2}{\c&HFFFFFF&}{\fnTahoma}checklist why to the speed

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain does something inexplicable

{\a2}{\c&HFFFFFF&}{\fnTahoma}pullback number one

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain's starting to shut down

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine one without fully understanding

{\a2}{\c&HFFFFFF&}{\fnTahoma}what the computer system is telling both

{\a2}{\c&HFFFFFF&}{\fnTahoma}engines are capable of producing power

{\a2}{\c&HFFFFFF&}{\fnTahoma}but because the right engine has

{\a2}{\c&HFFFFFF&}{\fnTahoma}feathered it has lost thrust behaving

{\a2}{\c&HFFFFFF&}{\fnTahoma}like a car in neutral gear when the

{\a2}{\c&HFFFFFF&}{\fnTahoma}captain pulls back the left throttle he

{\a2}{\c&HFFFFFF&}{\fnTahoma}leaves himself with no frost from either

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine he didn't seem to fully

{\a2}{\c&HFFFFFF&}{\fnTahoma}appreciate that that had halts Muttley

{\a2}{\c&HFFFFFF&}{\fnTahoma}resulted in number one engine being shut

{\a2}{\c&HFFFFFF&}{\fnTahoma}down to do such a thing

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators have discovered from the

{\a2}{\c&HFFFFFF&}{\fnTahoma}cockpit voice recorder that the captain

{\a2}{\c&HFFFFFF&}{\fnTahoma}of flight 235 shut down the plane's only

{\a2}{\c&HFFFFFF&}{\fnTahoma}working engine why didn't the first

{\a2}{\c&HFFFFFF&}{\fnTahoma}officer stop they continue listening to

{\a2}{\c&HFFFFFF&}{\fnTahoma}the recording trying to understand why

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain's mistake wasn't corrected

{\a2}{\c&HFFFFFF&}{\fnTahoma}in time we'll go back on engine 1

{\a2}{\c&HFFFFFF&}{\fnTahoma}throttle

{\a2}{\c&HFFFFFF&}{\fnTahoma}we can't just say he's gonna shut down

{\a2}{\c&HFFFFFF&}{\fnTahoma}the engine pilots are supposed to run a

{\a2}{\c&HFFFFFF&}{\fnTahoma}cross-check where one pilot verifies the

{\a2}{\c&HFFFFFF&}{\fnTahoma}actions of the other when the harlot

{\a2}{\c&HFFFFFF&}{\fnTahoma}flying shut down the operative engine he

{\a2}{\c&HFFFFFF&}{\fnTahoma}did so very quickly were they after

{\a2}{\c&HFFFFFF&}{\fnTahoma}discussing it with the pilot monitoring

{\a2}{\c&HFFFFFF&}{\fnTahoma}he's acting before even confirming what

{\a2}{\c&HFFFFFF&}{\fnTahoma}the emergency is when there's a warning

{\a2}{\c&HFFFFFF&}{\fnTahoma}come up the procedure says you identify

{\a2}{\c&HFFFFFF&}{\fnTahoma}the problem before you act

{\a2}{\c&HFFFFFF&}{\fnTahoma}no wait a second cross-check the pilot

{\a2}{\c&HFFFFFF&}{\fnTahoma}monitoring to his credit did try to stop

{\a2}{\c&HFFFFFF&}{\fnTahoma}the pilot flying from manipulating the

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine number one power lever and he

{\a2}{\c&HFFFFFF&}{\fnTahoma}announced he wanted to cross-check but

{\a2}{\c&HFFFFFF&}{\fnTahoma}there was no definitive confirmation

{\a2}{\c&HFFFFFF&}{\fnTahoma}from the pilot flying that the problem

{\a2}{\c&HFFFFFF&}{\fnTahoma}was engine number two adding more

{\a2}{\c&HFFFFFF&}{\fnTahoma}instead the captain interrupts the first

{\a2}{\c&HFFFFFF&}{\fnTahoma}officer to ask for a new heading we're

{\a2}{\c&HFFFFFF&}{\fnTahoma}below 2500 feet come on zero the first

{\a2}{\c&HFFFFFF&}{\fnTahoma}officer did tell the captain to wait he

{\a2}{\c&HFFFFFF&}{\fnTahoma}knows that the captain was pulling back

{\a2}{\c&HFFFFFF&}{\fnTahoma}on the wrong engine and when he did try

{\a2}{\c&HFFFFFF&}{\fnTahoma}to question it the captain just

{\a2}{\c&HFFFFFF&}{\fnTahoma}confirmed what he was doing all of a

{\a2}{\c&HFFFFFF&}{\fnTahoma}sudden they've got a dual engine failure

{\a2}{\c&HFFFFFF&}{\fnTahoma}and the pilot monitoring I think he's

{\a2}{\c&HFFFFFF&}{\fnTahoma}been caught off guard and he's not

{\a2}{\c&HFFFFFF&}{\fnTahoma}really sure what's going on

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}restart the engine I can't restart the

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}oh well I shut off the rocket

{\a2}{\c&HFFFFFF&}{\fnTahoma}the pilot flying Lily as an epiphany

{\a2}{\c&HFFFFFF&}{\fnTahoma}that they're in very dire trouble

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}shut up the rocket

{\a2}{\c&HFFFFFF&}{\fnTahoma}he's a very sad because we're not don't

{\a2}{\c&HFFFFFF&}{\fnTahoma}what when I heard him say I shut off the

{\a2}{\c&HFFFFFF&}{\fnTahoma}wrong engine when told I was completely

{\a2}{\c&HFFFFFF&}{\fnTahoma}devastated

{\a2}{\c&HFFFFFF&}{\fnTahoma}she said she never an uncle by the time

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain realizes his mistake it's

{\a2}{\c&HFFFFFF&}{\fnTahoma}too late unfortunately neither crew

{\a2}{\c&HFFFFFF&}{\fnTahoma}member actually followed the standard

{\a2}{\c&HFFFFFF&}{\fnTahoma}set of procedures for dealing with an

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine flame air after takeoff

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators now have an even more

{\a2}{\c&HFFFFFF&}{\fnTahoma}puzzling question to answer why didn't

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain understand what he was doing

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain's failure to recognize the

{\a2}{\c&HFFFFFF&}{\fnTahoma}situation and react properly ended up

{\a2}{\c&HFFFFFF&}{\fnTahoma}costing 43 lives he thought that the

{\a2}{\c&HFFFFFF&}{\fnTahoma}left engine had failed when the aircraft

{\a2}{\c&HFFFFFF&}{\fnTahoma}was clearly telling him it was the right

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine that had a problem how could the

{\a2}{\c&HFFFFFF&}{\fnTahoma}captain have got things so wrong

{\a2}{\c&HFFFFFF&}{\fnTahoma}oh is this captain's background when

{\a2}{\c&HFFFFFF&}{\fnTahoma}they dig into the captain's history they

{\a2}{\c&HFFFFFF&}{\fnTahoma}make a disturbing discovery

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain failed one of his key

{\a2}{\c&HFFFFFF&}{\fnTahoma}training components the pilot flying's

{\a2}{\c&HFFFFFF&}{\fnTahoma}training records had indicated that he

{\a2}{\c&HFFFFFF&}{\fnTahoma}was prone to being a bit anxious I have

{\a2}{\c&HFFFFFF&}{\fnTahoma}control you have control feeling a

{\a2}{\c&HFFFFFF&}{\fnTahoma}little bit overwhelmed in emergency

{\a2}{\c&HFFFFFF&}{\fnTahoma}situations and had a tendency to

{\a2}{\c&HFFFFFF&}{\fnTahoma}prematurely respond or act in that

{\a2}{\c&HFFFFFF&}{\fnTahoma}situation fall back number one

{\a2}{\c&HFFFFFF&}{\fnTahoma}I was also fired from his last job

{\a2}{\c&HFFFFFF&}{\fnTahoma}although the captain was an accomplished

{\a2}{\c&HFFFFFF&}{\fnTahoma}military pilot his civilian record is

{\a2}{\c&HFFFFFF&}{\fnTahoma}raising questions maybe he wasn't used

{\a2}{\c&HFFFFFF&}{\fnTahoma}to the eight years of 8600 the record

{\a2}{\c&HFFFFFF&}{\fnTahoma}soon confirmed that hunch leo cheon

{\a2}{\c&HFFFFFF&}{\fnTahoma}seong had logged relatively few hours in

{\a2}{\c&HFFFFFF&}{\fnTahoma}trans Asia's newest commuter plane the

{\a2}{\c&HFFFFFF&}{\fnTahoma}captain in the left-hand seat had

{\a2}{\c&HFFFFFF&}{\fnTahoma}approximately 5,000 hours total time and

{\a2}{\c&HFFFFFF&}{\fnTahoma}he had about 250 hours on the ATR 72 -

{\a2}{\c&HFFFFFF&}{\fnTahoma}600 the ATR 72 600 is known for its

{\a2}{\c&HFFFFFF&}{\fnTahoma}advanced technology investigators now

{\a2}{\c&HFFFFFF&}{\fnTahoma}wonder if this aircraft with its

{\a2}{\c&HFFFFFF&}{\fnTahoma}computerized glass cockpit was too

{\a2}{\c&HFFFFFF&}{\fnTahoma}complicated for a relatively

{\a2}{\c&HFFFFFF&}{\fnTahoma}inexperienced pilot to manage in a

{\a2}{\c&HFFFFFF&}{\fnTahoma}crisis they can often be overwhelmed

{\a2}{\c&HFFFFFF&}{\fnTahoma}with a few volume of information they

{\a2}{\c&HFFFFFF&}{\fnTahoma}also have to consider the nature of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}automation and the modes that are

{\a2}{\c&HFFFFFF&}{\fnTahoma}presented to them so it's more

{\a2}{\c&HFFFFFF&}{\fnTahoma}challenging

{\a2}{\c&HFFFFFF&}{\fnTahoma}I shut off the rocket did information

{\a2}{\c&HFFFFFF&}{\fnTahoma}overload lead to the deaths of 43 people

{\a2}{\c&HFFFFFF&}{\fnTahoma}in one of Taiwan's worst air disasters

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators need to know if the

{\a2}{\c&HFFFFFF&}{\fnTahoma}advanced technology designed to help

{\a2}{\c&HFFFFFF&}{\fnTahoma}pilots in the atr-72 600 may instead

{\a2}{\c&HFFFFFF&}{\fnTahoma}have contributed to the crash of flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}235 by confusing the trans-asia captain

{\a2}{\c&HFFFFFF&}{\fnTahoma}Hey ready to fly out of Taipei let's do

{\a2}{\c&HFFFFFF&}{\fnTahoma}it to try to find out they program a

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight simulator using the flight data

{\a2}{\c&HFFFFFF&}{\fnTahoma}from the downed plane we have weather

{\a2}{\c&HFFFFFF&}{\fnTahoma}information we have

{\a2}{\c&HFFFFFF&}{\fnTahoma}FDR data we have CBR data so we put

{\a2}{\c&HFFFFFF&}{\fnTahoma}those together to duplicate the

{\a2}{\c&HFFFFFF&}{\fnTahoma}condition of the accident the data lets

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators fly the exact same flight

{\a2}{\c&HFFFFFF&}{\fnTahoma}the same speed same climb rate and 37

{\a2}{\c&HFFFFFF&}{\fnTahoma}seconds into the flight the same cockpit

{\a2}{\c&HFFFFFF&}{\fnTahoma}alarm as the warning into flame at the

{\a2}{\c&HFFFFFF&}{\fnTahoma}planes computer instantly identifies

{\a2}{\c&HFFFFFF&}{\fnTahoma}which engine has lost thrust check

{\a2}{\c&HFFFFFF&}{\fnTahoma}autopilot earned Rena checklist the

{\a2}{\c&HFFFFFF&}{\fnTahoma}automated checklist pops up clear

{\a2}{\c&HFFFFFF&}{\fnTahoma}concise and easy to follow up trim on

{\a2}{\c&HFFFFFF&}{\fnTahoma}secure engine number two the checklist

{\a2}{\c&HFFFFFF&}{\fnTahoma}calls for the pilot monitoring to reduce

{\a2}{\c&HFFFFFF&}{\fnTahoma}power in the feathered engine to idle

{\a2}{\c&HFFFFFF&}{\fnTahoma}the other pilot guards the working

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine then you would bring the

{\a2}{\c&HFFFFFF&}{\fnTahoma}condition later into the fuel shutoff

{\a2}{\c&HFFFFFF&}{\fnTahoma}date on which removes fuel from the

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine doesn't leave a diffuser on check

{\a2}{\c&HFFFFFF&}{\fnTahoma}and then the engine will be secured and

{\a2}{\c&HFFFFFF&}{\fnTahoma}shut down and number two secured now

{\a2}{\c&HFFFFFF&}{\fnTahoma}powered by just one engine the plane

{\a2}{\c&HFFFFFF&}{\fnTahoma}keeps climbing safely on autopilot the

{\a2}{\c&HFFFFFF&}{\fnTahoma}computerized systems have helped the

{\a2}{\c&HFFFFFF&}{\fnTahoma}pilots avoid disaster exactly as

{\a2}{\c&HFFFFFF&}{\fnTahoma}designed it's quite manageable the crew

{\a2}{\c&HFFFFFF&}{\fnTahoma}can continue the flight climb to a safe

{\a2}{\c&HFFFFFF&}{\fnTahoma}altitude reconsider their options now we

{\a2}{\c&HFFFFFF&}{\fnTahoma}just have to fly it back to the airport

{\a2}{\c&HFFFFFF&}{\fnTahoma}at land I have an idea let's see what

{\a2}{\c&HFFFFFF&}{\fnTahoma}happens if we just let the plane fly

{\a2}{\c&HFFFFFF&}{\fnTahoma}itself hmm reset from the start setting

{\a2}{\c&HFFFFFF&}{\fnTahoma}when we do the simulator test we try to

{\a2}{\c&HFFFFFF&}{\fnTahoma}find out what will happen if the pilot

{\a2}{\c&HFFFFFF&}{\fnTahoma}do nothing

{\a2}{\c&HFFFFFF&}{\fnTahoma}incredibly the simulation shows that

{\a2}{\c&HFFFFFF&}{\fnTahoma}even if there had been no pilot input at

{\a2}{\c&HFFFFFF&}{\fnTahoma}all the plane would not have crashed the

{\a2}{\c&HFFFFFF&}{\fnTahoma}aircraft will continue climb in the fly

{\a2}{\c&HFFFFFF&}{\fnTahoma}was no problem so I think that the craft

{\a2}{\c&HFFFFFF&}{\fnTahoma}was designed to handle that situation as

{\a2}{\c&HFFFFFF&}{\fnTahoma}long as we don't do anything wrong any

{\a2}{\c&HFFFFFF&}{\fnTahoma}doubts about the glass cockpit have now

{\a2}{\c&HFFFFFF&}{\fnTahoma}been erased the advanced systems of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}ATR 72 600 did not lead to the crash of

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight 235 there must have been some

{\a2}{\c&HFFFFFF&}{\fnTahoma}other factor at play

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators study reports from

{\a2}{\c&HFFFFFF&}{\fnTahoma}previous incidents where similar

{\a2}{\c&HFFFFFF&}{\fnTahoma}mistakes were made

{\a2}{\c&HFFFFFF&}{\fnTahoma}they suggest an intriguing possibility

{\a2}{\c&HFFFFFF&}{\fnTahoma}interruptions and multitasking

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators know the captain's

{\a2}{\c&HFFFFFF&}{\fnTahoma}workload was high taking manual control

{\a2}{\c&HFFFFFF&}{\fnTahoma}of the plane distracted him from running

{\a2}{\c&HFFFFFF&}{\fnTahoma}a cross-check with his first officer he

{\a2}{\c&HFFFFFF&}{\fnTahoma}is multitask

{\a2}{\c&HFFFFFF&}{\fnTahoma}[Music]

{\a2}{\c&HFFFFFF&}{\fnTahoma}watch the speed

{\a2}{\c&HFFFFFF&}{\fnTahoma}it could have been suffering from change

{\a2}{\c&HFFFFFF&}{\fnTahoma}blindness change blindness people are

{\a2}{\c&HFFFFFF&}{\fnTahoma}focused or fixated on on another item or

{\a2}{\c&HFFFFFF&}{\fnTahoma}area of interest and so they miss what

{\a2}{\c&HFFFFFF&}{\fnTahoma}would be considered a very

{\a2}{\c&HFFFFFF&}{\fnTahoma}distinguishable change in the

{\a2}{\c&HFFFFFF&}{\fnTahoma}environment but they don't perceive it

{\a2}{\c&HFFFFFF&}{\fnTahoma}now we'll pull back into one throttle

{\a2}{\c&HFFFFFF&}{\fnTahoma}even when all the systems were telling

{\a2}{\c&HFFFFFF&}{\fnTahoma}him it was engine to his perception told

{\a2}{\c&HFFFFFF&}{\fnTahoma}him he was doing the right thing

{\a2}{\c&HFFFFFF&}{\fnTahoma}age -

{\a2}{\c&HFFFFFF&}{\fnTahoma}the first officer even tried to warn him

{\a2}{\c&HFFFFFF&}{\fnTahoma}no wait a second

{\a2}{\c&HFFFFFF&}{\fnTahoma}crusher it seems the captain was blind

{\a2}{\c&HFFFFFF&}{\fnTahoma}to the clear warning that his right

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine had feathered investigators

{\a2}{\c&HFFFFFF&}{\fnTahoma}finally understand what went wrong

{\a2}{\c&HFFFFFF&}{\fnTahoma}aboard trans-asia flight 235 a

{\a2}{\c&HFFFFFF&}{\fnTahoma}microscopic crack in a circuit board

{\a2}{\c&HFFFFFF&}{\fnTahoma}disabled an engine sensor that led the

{\a2}{\c&HFFFFFF&}{\fnTahoma}system to wrongly determine that the

{\a2}{\c&HFFFFFF&}{\fnTahoma}right engine had failed but that in

{\a2}{\c&HFFFFFF&}{\fnTahoma}itself wouldn't have caused the plane to

{\a2}{\c&HFFFFFF&}{\fnTahoma}crash this was a series of mistakes on

{\a2}{\c&HFFFFFF&}{\fnTahoma}the part of the captain when Engine 2

{\a2}{\c&HFFFFFF&}{\fnTahoma}feathered it captain reacted before he

{\a2}{\c&HFFFFFF&}{\fnTahoma}had properly assess a situation

{\a2}{\c&HFFFFFF&}{\fnTahoma}the captain should have followed a

{\a2}{\c&HFFFFFF&}{\fnTahoma}checklist I have control instead he

{\a2}{\c&HFFFFFF&}{\fnTahoma}turned off the autopilot and reduced

{\a2}{\c&HFFFFFF&}{\fnTahoma}power in the wrong engine I will pull

{\a2}{\c&HFFFFFF&}{\fnTahoma}back engine one throttle

{\a2}{\c&HFFFFFF&}{\fnTahoma}all we know for sure is he shut down

{\a2}{\c&HFFFFFF&}{\fnTahoma}they're only working engine at the time

{\a2}{\c&HFFFFFF&}{\fnTahoma}he realizes it's too late restart the

{\a2}{\c&HFFFFFF&}{\fnTahoma}engine I can't restart the engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}well shit after engine

{\a2}{\c&HFFFFFF&}{\fnTahoma}while it says Asia hiatus pilot

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators dig into trans Asia's

{\a2}{\c&HFFFFFF&}{\fnTahoma}corporate background check this out

{\a2}{\c&HFFFFFF&}{\fnTahoma}trying to understand how a pilot with

{\a2}{\c&HFFFFFF&}{\fnTahoma}such a poor record ever got through the

{\a2}{\c&HFFFFFF&}{\fnTahoma}door and this this company has been

{\a2}{\c&HFFFFFF&}{\fnTahoma}expanding rapidly what they find paints

{\a2}{\c&HFFFFFF&}{\fnTahoma}a picture of a growing company

{\a2}{\c&HFFFFFF&}{\fnTahoma}struggling to compete with bigger

{\a2}{\c&HFFFFFF&}{\fnTahoma}players in the competitive Asian market

{\a2}{\c&HFFFFFF&}{\fnTahoma}the more regional operator like

{\a2}{\c&HFFFFFF&}{\fnTahoma}trans-asia Airways fees to struggle to

{\a2}{\c&HFFFFFF&}{\fnTahoma}certainly recruit and retain the sort of

{\a2}{\c&HFFFFFF&}{\fnTahoma}expertise that airlines seek the crash

{\a2}{\c&HFFFFFF&}{\fnTahoma}of flight 235 would be the last accident

{\a2}{\c&HFFFFFF&}{\fnTahoma}for trans Asia Airlines in November 2016

{\a2}{\c&HFFFFFF&}{\fnTahoma}the company ceased operations and went

{\a2}{\c&HFFFFFF&}{\fnTahoma}out of business there's a multitude of

{\a2}{\c&HFFFFFF&}{\fnTahoma}reasons that the board decided to shut

{\a2}{\c&HFFFFFF&}{\fnTahoma}down the the airline but there's an

{\a2}{\c&HFFFFFF&}{\fnTahoma}inescapable conclusion that the adverse

{\a2}{\c&HFFFFFF&}{\fnTahoma}will poor safety performance of the

{\a2}{\c&HFFFFFF&}{\fnTahoma}airline certainly had an economic impact

{\a2}{\c&HFFFFFF&}{\fnTahoma}on the airline even though trans-asia

{\a2}{\c&HFFFFFF&}{\fnTahoma}Airlines no longer flies air crash

{\a2}{\c&HFFFFFF&}{\fnTahoma}investigators hope that the tragedy of

{\a2}{\c&HFFFFFF&}{\fnTahoma}flight 235 will serve as an important

{\a2}{\c&HFFFFFF&}{\fnTahoma}safety reminder to pilots at other

{\a2}{\c&HFFFFFF&}{\fnTahoma}airlines around the world

{\a2}{\c&HFFFFFF&}{\fnTahoma}we all understand that pilot the human

{\a2}{\c&HFFFFFF&}{\fnTahoma}human make mistakes so that's why we

{\a2}{\c&HFFFFFF&}{\fnTahoma}design the standard operating procedures

{\a2}{\c&HFFFFFF&}{\fnTahoma}and the basic important thing is or

{\a2}{\c&HFFFFFF&}{\fnTahoma}people just follow the procedure
