00:00While a passenger live-streams an approach into Pokhara Airport in Nepal...
00:06The plan is to go paragliding with my buddies!
00:13Add power!
00:16Yeti Flight 691 falls from the sky.
00:22What's happening?
00:2872 people are killed.
00:31This was the deadliest crash involving Nepali Airlines ever.
00:40Eyewitness video gives investigators their first lead.
00:44That's at least an 80-degree left bank.
00:50When they analyze the flight data...
00:53Wow.
00:54They're shocked to discover the engines weren't generating power.
00:59No power, torque indication zero!
01:01There should have been warning lights.
01:03Why didn't they figure it out?
01:05You start to question, what was going on in the cockpit?
01:09Me, me, me, me!
01:10I'm hearing about one minute.
01:18I'm hearing about two minutes.
01:19There's not enough speed.
01:20I'm hearing about one minute.
01:20We're gonna be able to go on the cockpit.
01:26It's not enough speed.
01:29From the right people are flying to the pressure.
01:33These cars are still has to.
01:33Heat heat.
01:35One, two, three.
01:35Two, three.
01:35One, four.
01:36One, four.
01:36One, three.
01:36One, four.
01:36Three, four.
01:37One, three.
01:43There are 68 passengers on board, including Sonu Jaiswal, a tourist from India, heading to Pokhara to paraglide with friends.
01:57Pokhara Tower, Yeti 691, descending through 12,500 feet.
02:04Captain Kamal Casey is the senior officer and the pilot monitoring instruments on today's flight.
02:10Roger, Yeti 691, 12,500 feet.
02:15He's also a veteran of more than 21,000 flying hours.
02:22We had absolutely the utmost respect for Captain Kamal Casey as he was a veteran in the Nibali skies, and
02:31he was quite a humble and knowledgeable guy as well.
02:36It's very clear. We'll be good for visual landing.
02:41Flying the plane from the left-hand seat is Captain Anju Katewada. She's flown more than 6,000 hours.
02:50Captain Katewada has a very special history.
02:54Her husband, he was a pilot with the same company.
02:57He was the first officer on the twin order, and it crashed, and he died some years earlier.
03:02Captain Katewada decided to take up flying to honor his spirit, so she'd become a pilot.
03:118,500 feet.
03:13While Captain Katewada is an experienced commercial pilot, she has only 186 hours on the ATR-72.
03:30The ATR-72 is a turboprop twin-engine aircraft.
03:35It's a high-wing aircraft.
03:38It's a very stable, predictable, and logical aircraft.
03:42And it's very good to fly here in the mountains and hilly regions of Nepal.
03:51Today's flight is a short 25-minute hop from Kathmandu to the tourist city of Pokhara.
04:02Yeti 691, expect to land on 1-2.
04:06Broadway 1-2, Yeti 691.
04:0915 miles from the airport, Yeti flight 691 is cleared for the approach.
04:17Hey, everyone. Exciting times as we're headed to Pokhara's new airport.
04:21Sonu Jaiswal is live-streaming from the cabin.
04:24The plan is to go paragliding in the Himalayan foothills with my buddies.
04:333-1-0.
04:35Captain Katewada programs a heading.
04:38For the approach to runway 1-2.
04:44You are in between the runway and the mountains.
04:48So you need to be very, very precise with your handling skills of the aircraft.
04:56Okay, visual, visual.
04:58Okay, visual.
05:00The pilots monitor their position carefully, keeping the plane clear of the mountains.
05:09Yeti Airlines 691 in sight, report final, runway 1-2.
05:14Call you on final for runway 1-2.
05:16Yeti Airlines 691.
05:21Gear down.
05:25Less than two minutes from the airport, the pilots configure the plane for landing.
05:31Okay, from here you can go manual.
05:33Okay, standby.
05:38Disconnect.
05:40Captain Katawada disconnects the autopilot, then begins the first of two crucial turns to line up with the runway.
05:55Okay, flaps 30.
05:58Flaps 30.
06:01Continue descent.
06:03Okay.
06:07One minute from touchdown, the pilots run through the pre-landing checklist.
06:13Okay, landing gear.
06:14Down three green.
06:16Flaps?
06:1630.
06:21In the cabin, Sonu Jaiswal continues live streaming.
06:26We're getting pretty close now.
06:30As the flight gets closer to the ground, the landing seems trouble-free.
06:41But seconds from the runway, Captain K.C. realizes there's a critical problem with the engines.
06:47There's no power.
06:50There's no power.
06:53When there's no power, that means they have very limited time at that altitude.
06:59They need to react quickly.
07:02Add power.
07:04Captain Katawada tries to power up, but the engines aren't producing any thrust.
07:12400 feet above the ground, the pilots face a critical situation.
07:20In the tower, the controller doesn't know that Flight 691 is in any trouble.
07:25Yeti 691, runway 12.
07:28Clear to land.
07:30There's no power.
07:32No power.
07:33Add power.
07:37Captain Katawada pushes the throttles to the limit.
07:44There's no torque.
07:45Okay, give it to me.
07:48The more senior captain takes control.
08:03Flight 691 is stalling.
08:13Flight 691 is stalling.
08:22What's happening?
08:26What's happening?
08:29What's happening?
08:31What's happening?
08:31What's happening?
08:31What's happening?
08:31What's happening?
08:34What's happening?
08:36What's happening?
08:36What's happening?
08:37What's happening?
08:38What's happening?
08:38What's happening?
08:40What's happening?
08:42What's happening?
08:43What's happening?
08:56Yeti flight 691 has crashed in one of the worst possible places.
09:03The Shethi river runs near to the airport through a huge gauze.
09:08That's where the plane crashed.
09:13The plane was completely destroyed in the impact.
09:18There was a huge flame burning.
09:23There was no possibility to find any survivor.
09:30The bodies of 71 of the 72 passengers and crew are eventually found and identified, including both pilots.
09:41This was the deadliest crash involving Nepali Airlines ever.
09:49What could have caused a commercial airliner to drop out of the sky just seconds before landing?
10:03When investigators arrive at the crash site of Yeti flight 691, they face a devastating scene.
10:13The wreckage was scattered all over the place.
10:18The first impact was before the river, where the parts of the left wing was detached.
10:24Some parts were located on the bottom of the river guards.
10:26The rest of the pathway at the side of the river.
10:35Under the supervision of Nepali investigators, the wreckage, along with the black boxes and central processing card from the plane's
10:44computer,
10:44are sent for analysis to labs in France and Singapore.
10:50It's really not uncommon in an accident investigation to have to send something out for closer investigation.
11:05Nepali investigators wonder about flight 691's orientation when it hit the ground.
11:12It looks like this is from the first point of impact.
11:16That's a flap from the left wing.
11:19And an aileron tip.
11:22So the left wing must have hit the ground first.
11:29The plane crash is winged down.
11:31What that suggests to investigators is that the plane crashed out of control.
11:36You would never intend to have it be that way.
11:38You'd always try and level it out and crash as close to a regular attitude as you can.
11:44Maybe the plane stalled.
11:48You may be right.
11:50Check this out.
11:58It's gone viral.
12:05A witness had filmed the plane during the final moment of the flight.
12:11It appears that the left wing lost lift and dipped severely.
12:17That's at least an 80-degree left bank.
12:25It sure looks like a stall to me.
12:32When you see evidence that looks like a stall,
12:35you immediately start questioning what could have led to that,
12:38and you go back to what's going on during that approach.
12:48This is not an easy approach.
12:51They'd have to fly between the runway and the mountain
12:55and make two left turns before lining up with runway 12.
13:00And this is where the plane crashed.
13:02And just before the crash, they were beginning their final left turn.
13:08Did the pilots bank too far during one of the turns and stall?
13:15They would have had to go from zero to an 80-degree bank in a few seconds.
13:20Yeah.
13:23It suggests there was a problem with the plane.
13:26Yeah.
13:29You might want to focus and see if there's any smoking guns in the maintenance records.
13:33If there was anything wrong that somebody knew about,
13:36maybe they tried to fix it and it didn't get fixed.
13:40I've got maintenance records.
13:47Investigators go through the plane's records
13:50in search of any gaps in maintenance or inspections.
13:56Not seeing anything.
13:59Everything checks out.
14:02Maybe the controller knows something.
14:06Yeah.
14:08The air traffic controller may have heard something
14:11in their conversation with the pilots,
14:13picked up something that isn't really evident from the tape.
14:19Did you have visual contact with the aircraft?
14:27Did you see or hear anything suggesting a problem with the plane?
14:31No.
14:32I was flying normally when I had visuals with it.
14:34It was just out of sight right before the crash.
14:39Then I heard it.
14:43Explosion.
15:01Did the pilots say anything suggesting a problem with the plane?
15:05Nope.
15:05No, I'm not sure.
15:08Okay.
15:10Thank you.
15:12So, do you know what happened?
15:19Not yet.
15:27In the early stages, you'd want to look at anything witnesses might have to say,
15:32anybody who might have seen, heard, or otherwise noticed the crash.
15:37The controller offers little insight into why the plane stall.
15:41Then a witness to the accident comes forward.
15:44There?
15:45That's where you saw the plane?
15:49He had the credibility because he was an engineer.
15:53And you said that you saw the propeller spitting just before the crash?
16:01When you see a propeller rotating, it means it moves very slow.
16:05Otherwise, you cannot see it moving.
16:10The slow rotation of the propellers could indicate there was a problem with the engines that drive them.
16:23We need to talk to the French about their engine analysis.
16:31Hola
16:35Napoleón investigadores
16:37now joined the team from France
16:39to examine the wreckage
16:40of Yeti Flight 691
16:43Engines are badly damaged
16:46Can't tell
16:46if they failed in flight
16:51Most of the engines
16:52were consumed by fire
16:53so they couldn't learn definitively
16:56whether they were producing power
17:01Look at that prop
17:05Investigators notice
17:06something telling on a propeller hub
17:12Looks feathered
17:22When propellers are feathered
17:24their edges face forward
17:26and cannot produce thrust
17:29It's like putting your car
17:31in neutral position
17:32You can push on the gas
17:34as much as you want
17:35but nothing is going to happen
17:41It's actually stuck
17:42in a feathered position
17:51This one moves freely
17:53but it could have moved on impact
18:01This one is stuck too
18:04So
18:05two of them
18:06were in the feathered position
18:07when they hit the ground
18:13Normally
18:13propellers are feathered
18:14on the ground
18:15after shutdown
18:16that prevents them
18:17from spinning in the wind
18:19and damaging the engine
18:21There is however
18:22one exception
18:24An automatic feathering unit
18:25will feather that
18:26propeller immediately
18:27as soon as
18:28an engine failure is detected
18:29perhaps faster
18:31than the pilot can do it
18:35Were the props
18:36feathered automatically
18:37in flight
18:38due to engine failure?
18:40Investigators download
18:41the data
18:41from Flight 691's
18:43multifunction computer
18:44to find out
18:45The multifunction computer
18:48stores information
18:49about the automatic feathering unit
18:50in its memory
18:53They're going to be able to learn
18:55whether the auto feather unit
18:57feathered one engine
18:58or both engines
19:09It never activated
19:12If you learn
19:13that the auto feather system
19:15didn't feather
19:16the propellers
19:17that immediately
19:18raises the question
19:19who or what did?
19:23Were the propellers
19:24feathered manually?
19:26Investigators consider
19:27a crucial piece of wreckage
19:29recovered from the scene
19:30the central control pedestal
19:32The central pedestal
19:35is located between
19:36the pilots
19:36and here you have
19:38the power levers
19:39you have the flaps lever
19:41and you have the condition levers
19:42which controls
19:43the propellers
19:46flaps are stuck at 30
19:49that's where they should be
19:50for landing
19:54condition levers
19:54are moving freely
19:55It doesn't tell us much
19:59Look at this
20:09witness mark
20:13You're looking for witness marks
20:15You're looking for witness marks
20:15the marks that one aircraft component
20:17makes against another
20:18at the time of impact
20:19and those marks
20:22will suggest
20:22in the case of the central control pedestal
20:25where the controls
20:26were positioned
20:27at impact
20:30The witness mark
20:31suggests that the pilots
20:32could have put the left lever
20:34in the feathered position
20:37Maybe some other debris
20:38caused the witness mark
20:40There's no witness mark
20:41for the right condition lever
20:47Were the propellers feathered
20:48by the pilots
20:49or did the witness marks
20:51occur on impact?
20:53We're going to need
20:54the flight data recorder
20:55download to settle this
21:01The flight data recorder
21:02doesn't record
21:03the propeller blade angle
21:05but it does record
21:07certain parameters
21:08that let investigators
21:09infer
21:09whether the propellers
21:11were feathered
21:12and if so
21:12when
21:21Wow
21:24The torque and propeller speed
21:25drop at the same moment
21:28but the engine's at idle
21:31They find evidence
21:33that the pilots
21:34feathered the props
21:35one minute before the crash
21:38When the propellers are feathered
21:40the torque drops
21:41and the propeller's RPM
21:42speed drops
21:45That's what the witness
21:46was able to see
21:47when he reported
21:48spotting the individual
21:50propeller blades
21:51How did they make that mistake?
21:59What was going on
22:00in the pilot's mind?
22:03What was going on
22:04in the cockpit?
22:05What's happening?
22:18Pick it up 24 minutes
22:20into the flight
22:20right before
22:22the propellers were feathered
22:25Investigators listen
22:26to the cockpit voice recording
22:28from Yeti Airlines
22:29flight 691
22:30to understand
22:31why the pilots
22:32feathered their propellers
22:33when they did
22:35Okay, from here
22:36you can go manual
22:37Okay, stand by
22:42Disconnect
22:44Okay, flaps 30
22:47Flaps 30
22:50Continue descent
22:51Okay
22:53Stop, Thompson
22:55Where are we at here?
22:57Time is
22:5810, 56, 35
23:04According to the FDR
23:07The flaps did not move
23:09to 30 at this point
23:10But this is
23:11when the props were feathered
23:16The FDR shows
23:18that when the pilot
23:19flying commanded flaps 30
23:21the flaps didn't move
23:23But at the same moment
23:24the prop RPM decreased
23:26and torque went to zero
23:29The pilot
23:30has pretty obviously
23:32feathered the engines
23:33instead of moving the flaps
23:42They must have mixed up
23:43the flap levers
23:44with the condition levers
23:47And Captain Casey
23:48was the pilot monitoring
23:52How could a captain
23:53make that mistake?
23:59In most airline accidents
24:02pilot error is a factor
24:04That can be because
24:06of inadequate training
24:08experience
24:09It can be because
24:11of too little rest
24:13But there can also be
24:15other factors
24:16impairing their decisions
24:18Here you go
24:24The team reviews results
24:26from the pilot's
24:27toxicology tests
24:31Nothing on Captain
24:32Katiwata
24:38Same with Captain Casey
24:43Maybe they weren't
24:44adequately rested
24:48According to the airline's
24:49records
24:49both pilot schedules
24:50were within guidelines
24:52suggesting adequate rest
24:54And their medical
24:55certificates are current
24:58They conclude that
24:59something other
25:00than impaired judgment
25:01caused the pilots
25:03to feather the props
25:04by mistake
25:05At this point
25:06you'd have to wonder
25:07what might have been
25:08going on in the cockpit
25:09that would lead him
25:10to be distracted
25:11into setting
25:12the propellers
25:13to feather
25:14instead of setting
25:15the flaps
25:15for landing
25:18Did the location
25:19of the condition
25:20levers on the pedestal
25:21play a part
25:22in the captain's error?
25:24They examine
25:25an ATR-72 pedestal
25:29I reach over
25:30for the flaps
25:32but I put my hand
25:34on the condition
25:34lever instead
25:40The flap lever
25:41and the condition lever
25:42are very close
25:43together on the pedestal
25:46I want to move
25:47the flaps
25:47to the 30 degree position
25:51but instead
25:54I move the condition lever
25:57to feathered
26:08It's not a stress
26:10It's not a stress
26:10that they could have
26:10mixed up the levers
26:12And don't forget
26:13Captain Casey
26:14was where I'm sitting
26:17Right
26:23Mercer memory
26:24is very important
26:25for a pilot
26:25because you can do
26:26sequences
26:27without being
26:28conscious about it
26:30But when you move
26:31to another seat
26:32on the other side
26:33suddenly that flow
26:35is disturbed
26:36because now
26:36you have to use
26:37the opposite hand
26:41Oh, that feels
26:42a lot less natural
26:46and much easier
26:47to mix up
26:51Okay
26:52flaps 30
26:54Flaps 30
26:57Continue descents
27:01The pilot monitoring
27:02moved the condition levers
27:04instead of the flap lever
27:05That should be impossible
27:07but it has happened
27:09before
27:11I once asked
27:12for flaps
27:13and the pilot monitoring
27:15selected the gear down
27:17and those layers
27:18are far apart
27:22Still, it's hard
27:23to imagine
27:23looking at these levers
27:25that you'd get them
27:26confused
27:27True
27:35Maybe he wasn't
27:36looking at them
27:40Why would an experienced captain
27:43not check
27:44which levers
27:45he was moving?
27:50Okay, visual, visual
27:51Okay, visual
27:54Investigators returned
27:55to the voice recording
27:56of Yeti Airlines
27:57Flight 691
27:59to determine
28:00if the captain's attention
28:01was elsewhere
28:02when he selected
28:03the wrong levers
28:04Okay, make sure
28:04you stay between
28:05the mountains
28:05and the runway
28:08They revisit the moment
28:09just before
28:10the propellers
28:10were feathered
28:12Keep your power nose up
28:14Keep visual with the tower
28:15Don't go too far
28:17Okay, copy that
28:21Okay, stop for a second
28:25He's giving her
28:26a lot of instructions
28:29Maybe that's the distraction
28:32But she's a very experienced pilot
28:34So why is he doing that?
28:38When you're giving instruction
28:39that's an added mental stress
28:41It's an added cognitive load
28:43It's very distracting
28:45Let's start from the top
28:47Poker Tower
28:50Yeti Airlines 691

28:57Yeti 691
28:59Descending through
29:0012,500 feet
29:01Roger
29:03Yeti 691
29:0412,500 feet
29:06Expect to land
29:08on runway 30
29:10Runway 30
29:11Yeti 691
29:15They discover
29:16that flight 691
29:18was initially
29:18cleared to land
29:19on a different runway
29:21runway 30
29:22But eight minutes later
29:24there's a change of plan
29:26If traffic permits
29:27let's land on runway 12
29:29Then you'll be approved
29:31for runway 12
29:32without any instructor
29:33or pilot supervision
29:34Okay
29:35runway 12
29:38Not only is he
29:39monitoring the flight
29:40he's approving her
29:42to land at
29:42Pokhara's new airport
29:46Investigators discover
29:47Captain Casey
29:48was instructing pilots
29:49on how to land
29:50on both runways
29:52at the new airport
29:54I flew with
29:56Captain Kamal Casey
29:57just two days before
29:58for my route qualification
29:59into Pokhara
30:00International Airport
30:03But why runway 12?
30:08You'll be approved
30:09to land in both directions
30:10Copy that?
30:17Okay, stop it
30:18So Captain Katiwada
30:21is cleared for runway 30
30:24And Captain Casey
30:25decides much later
30:27in the game
30:27he's approving her
30:28for runway 12
30:31Captain Katiwada
30:32had landed on runway 30
30:34but never 1-2
30:37Runway 30
30:38is a straight-in approach
30:43In runway 12
30:45you follow a narrow track
30:47next to the mountains
30:48and you turn left twice
30:50to line up with runway
30:52So Captain Casey
30:53put Captain Katiwada
30:55on a more difficult landing
31:02Runway 1-2
31:03was a challenging approach
31:04for a pilot
31:05with just
31:05185 hours
31:07on the 8th year
31:09Did Captain Casey
31:11properly prepare
31:12Captain Katiwada
31:13for the difficult approach
31:14to runway 1-2?
31:18The best way
31:19to prepare a pilot
31:20for such an approach
31:21would be
31:22to do
31:23a proper briefing
31:24Maybe they have
31:25photos, videos
31:27simulator training
31:28if available
31:32Investigators examine
31:33Captain Katiwada's
31:34training records
31:37She spent no time
31:39in the simulator
31:39training on runway 1-2
31:41What about
31:42a formal briefing?
31:44There's no documentation
31:45related to training
31:46on 1-2
31:48I've got Captain Casey's
31:49flight history
31:52Was Captain Casey
31:53even qualified
31:54to train others
31:55for landing
31:56on runway 1-2
31:57Turns out
31:58he had only
31:59landed on 1-2
32:00twice
32:00A bit of experience
32:04but
32:05not enough
32:09Because of his
32:10low experience
32:11and also
32:12Katiwada's
32:13low experience
32:13on the aircraft
32:14I find that
32:16a bit strange
32:18I wonder
32:19if it's even
32:20possible
32:20to do
32:21a stabilized
32:22visual landing
32:23using that
32:24approach
32:32A stabilized
32:34visual approach
32:35is one
32:36that's conducted
32:36with the runway
32:37in sight
32:38at a normal
32:39rate of descent
32:40with landing flaps
32:41and landing gear
32:43down
32:43at the proper
32:44airspeed
32:45and with all
32:46checklists
32:46completed
32:47by a certain
32:48point
32:50There's just
32:51over one mile
32:52between the
32:52completion
32:53of the last
32:54turn
32:54and the runway
32:57That's going
32:58to give you
32:58just over
32:5930 seconds
33:00from lining
33:00up to landing
33:01It's very
33:02tight
33:08A visual
33:09landing
33:09can increase
33:10the workload
33:11because
33:11they have
33:12to make
33:12tiny adjustments
33:13all the way
33:14through the
33:14pattern
33:16Let's see
33:17how they
33:17handle
33:17the workload
33:20Okay
33:21make sure
33:21you stay
33:21between
33:21the mountains
33:22and the runway
33:23To understand
33:25how the pilots

39:35He decided to fly the plane rather than try to diagnose the problem.
39:49One
39:50seeing a glance around the cockpit could have told him that he had feathered the propellers.
40:01The final report of the Napoli Accident Investigation Commission concludes that the most probable cause of the accident
40:08was the inadvertent movement of both condition levers to the feathered position in flight.
40:16What strikes me about this is that it was a very normal situation.
40:21The only thing that went between success and failure was the slip of a hand.
40:30The proximity to terrain and sharp turn required to land on runway one two.
40:37Before landing checklist.
40:38Combined with a high workload and a lack of appropriate training all contributed to the crash.
40:47After the accident, Yeti Airlines tests the approach in the simulator with their pilots.
40:54Most of our pilots were not able to land on runway one two.
40:58Either they were high on approach or they were fast on speed.
41:06Yeti Airlines stops flying into runway one two until they are able to establish a safe visual procedure
41:13and retrain their pilots.
41:16The commission recommends that the civil aviation authority of Nepal ensures that a stabilized flight path is approved
41:23before allowing commercial operations at a new airport.
41:30After the accident, the victims of Yeti Air Flight 691 are mourned by a nation and fellow pilots remember their
41:39colleagues.
41:41For Captain Kamal Casey, I just want to remember him when he was alive and he was there with us.
41:53Captain Khatiboda, I respected her a lot.
41:58Captain Khatiboda, she will be remembered as an elder sister and there is going to be always a void in
42:05the airlines that she is not there anymore.
42:12Captain Khatiboda, she gave her a lot of bamboo turns on.只剩
