"We Need To Land IMMEDIATELY"; Amazon Prime 767 Reduced to Single Electrical Source! [ATC audio]

GET EARLY ACCESS TO VIDEOS ON PATREON: / airtrafficvisualised
May 26, 2022. An Amazon Prime Air Boeing 767-300ER(BCF) is operating an early-morning flight from Los Angeles to Seattle. As the aircraft climbs, the electrical generator connected to the right engine fails. The aircraft’s APU is inoperative, leaving the crew with a single source of electrical power - the left engine’s generator. They declare an emergency and turn around for an immediate landing in Los Angeles. Watch and listen as the pilots and air traffic control coordinate to get the aircraft back on the ground safely.
Flight Number: 8C1917 / ATN1917
Route: Los Angeles International Airport (LAX / KLAX) ❯ Seattle-Tacoma International Airport (SEA / KSEA)

That happened to me several times... but I flew the MD11 for FedEx with 3 generators, and, like Meatloaf, said "two out of three ain't bad."

[@ArtyI]

That's not a problem. I assume the MD11 could also run off of a single source of power, but that creates a single point of failure which you don't want in the sky

the Commuter flight and lay over for me going to Chicago got hit by lightning right beside my window seat. The Black Woman beside me tried to crush my hand. I simply looked at her and said. (If there was a hole in this Airplane? We would have been a deck of cards at 400 MPH and 33 Thousand feet. We are Good.) Warmest hug when on the ground. Moms.

[@alphasiera1757]

Wow you still fly md11, wonder how long it will be in service since it has a high jet gas consumption

[@AlphaGametauri]

@@alphasiera1757 FedEx and UPS doesn't plan to retire their MC-10's or MD-11's anytime soon, their reasoning is it's cheaper to maintain and fuel a more expensive to run jet like them, then it is to buy brand new jets such as the 787 or A350, and have to change up their maintainence departments and such

[@NVRAMboi]

No panic. No nonsense. All parties laser-focused. This level of professionalism is a credit to both ATC and commercial pilots.

[@SKYGUY1]

On the 1983 day of my Private Pilot check-ride in a C-150, I left my check-ride airport as the sun was going over the horizon. I had a 40 minute flight from Rutherford County, NC airport back to my home base in Boone, NC. (at that time) an unlighted grass strip in the Appalachian Mountains. About halfway home I had a complete electrical failure... mind you now, I'm a rookie w/ a dripping wet PP license. I got back and the one street light at the tie-down corner of the airport was my only light. I held my flashlight in my mouth and kept it focused on the airspeed indicator, remembering that my flaps don't work, kept my speed up about 5 kts higher than usual and made an uneventful landing. I taxied back to tiedown, an some of the other plane owners were there and quizzed me about my landing lights and nav lights being out. I got a commendation from them all. 25 years later, it happened again in a Piper Archer (At least I had flaps) that I was ferrying back from maintenance at night. Now, as an Instructor, I "overemphasize" the importance of having a small flashlight at hand (not in a bag), and perhaps a portable navigator of some type if going to far reaching destinations. AND... when things go wrong... JUST FLY THE PLANE!!!

[@dne9394]

I had this exact same thing happen. It’s not an “emergency” in the manner that most may think. Everything on the jet is working normally and there is no significant degradation of capability, unless the weather is very, very bad. If the last generator were to quit, that becomes a very significant problem, and most jets like this one (I drive this same jet) have less than 30 minutes to get on the ground. When it happened to me, I was over Memphis, during the FedEx busy time. There were no issues at all working in with traffic. Again, all a “precautionary landing”. Declaring an emergency does two major things. Alerts ATC there is an issue and special services are being requested. It gives the Captain legal authority to do what he needs to in order to get on the ground. For the crew, that approach and landing were as normal as all the others they have done.

[@someguy4915]

To be fair, does't the captain always have legal authority (and the responsibility) to ensure the safety of the aircraft and those aboard it? If ATC tells a non-emergency aircraft to do a barrel-roll the captain would most likely not attempt it despite not having declared an emergency :P

[@kilianortmann9979]

Im not sure how it is on the 767, maybe you can confirm, but isn't the Ram Air turbine also producing some electricity.

[@TwinShards]

"If the last generator were to quit, that becomes a very significant problem, and most jets like this one (I drive this same jet) have less than 30 minutes to get on the ground." I guess if this were to happen, it would be to completely turn off electrical power and glide as far as possible util the altitude is too low to be "safe" then use those ~30minutes left

I heard normal traffic every day but a few times I'd catch something unusual. I could also pick up ATC of planes talking to Oakland Center. One thing that stuck in my memory was that airline pilots would sometime be told to "Delete the Boulder (speed) restriction" and the pilots often confirmed with "Drop the rock" but it took me a while to understand the slang.

After the Hudson 737 landing, it's amazing to me that they continue allowing planes to fly with a non-working APU. Captain Sully's starting the APU was credited as the #1 technical thing that saved them, as it restored their electrical power even with all engines out. A broken APU should be a non-airworthy state.

[@ArmyofSeaturtles]

Keep in mind that this was at 5am local time - the aircraft you see on the display represents the total traffic into and out of LAX at the time.

[@blusheep2]

Magu was below them 19000 feet. ATC would have had to vector them out quite a ways to give them time to descend, so Magu isn't really a more efficient airport to land at, not to mention its military airfield which isn't set up for commercial airliners and passengers. Generally pilots will opt for the large airport which has longer runways, company support and good fire and rescue. There are time and no-time emergencies. A fire would be a no-time emergency. You get it on the ground as soon as you can. This electrical problem was not a no-time emergency.

[@schubey_t6841]

Likely due to maintenance oversight to keep amazon profits high.

[@OfficialSamuelC]

My concern in these incidents, where I understand ATC still want to get other planes in, but if one of the planes they’re squeezing in before the emergency aircraft has an issue on the runway, that runway is now no longer available to the emergency aircraft and god knows what problems that could cause in certain emergencies. Arguably in some emergencies the pilots could decide that if the aircraft ahead (which had no problems prior to landing) has had an issue at the end of the runway but is still on it, but they haven’t got an option to go around, that the best option is to go against ATC and land on that runway despite there being another aircraft on it at the end. Obviously this wouldn’t work if the other aircraft is well within the normal landing distances. But if you’ve got no engines, a fire or whatever, it’s better to get down and perhaps do a runway excursion to avoid the problem aircraft ahead or have a collision with it, than try go around and fall out of the sky. But again, brings back the Russian roulette of hoping all aircraft you squeeze in perfect their landings and don’t have any issues or delays on landing. Obviously in this case it wasn’t necessarily AS time critical as a fire/no engines (still urgent), and they could’ve gone around and likely found an alternative landing, but still seems risky. I would want to preserve that runway when the emergency aircraft is about to begin their approach. But again, they have to balance the logistics of the airport and getting other aircraft down and not having other emergencies in the way of emergency fuel being declared and so on. I think in the serious outcomes the ATC should just advise the wait is a minimum of x time based on how long it’ll take the emergency aircraft to get from wherever they are and until landing, and that aircraft can decide whether they can hold for that long or divert.

[@ndbiet]

It seem the pilot still have control and has not declare a Mayday and quite calm so it is reasonable why ATC allow this to happen

[@TianarTruegard]

@@ndbiet They did declare an emergency (mayday). Depending on the aircraft, complete electrical failure could leave them unable to control the aircraft and crash at worst, or unable to communicate at best. Granted, they still had 1 generator operational and there are batteries on aircraft as well, but those only last a few minutes if all generators fail. If a pilot declares an emergency ((assuming its legitimate)), ATC is supposed to give them priority, period. It could have gotten rather messy if that runway wasn't clear for the emergency aircraft when they landed.

Seems a bit unusual to me to have the north part of the airport landing EB and the south field departing WB. Nice display, though.

[@AirTrafficVisualised]

This occurred at about 5 am local time, so the airport isn't particularly busy, and the weather was fair. For noise abatement, they depart and arrive over the ocean.

[@NicksStuff]

So, they still had one electrical source, plus the battery, plus the ram air turbine, and both engines, correct?

[@AirTrafficVisualised]

No, the aircraft was dispatched with the APU inop. When the right engine generator failed, they were down to a single source - the left engine's generator. The battery and RAT can supply power to some systems, but losing all other sources of electrical power would constitute a serious emergency.

[@BadMonkeyTouring]

I'm always shocked at how many professional pilots do not use proper terminology when declaring an emergency. The FAA says: EMERGENCY DETERMINATIONS An emergency can be either a Distress or an Urgency condition as defined in the “Pilot/Controller Glossary.” A pilot who encounters a Distress condition should declare an emergency by beginning the initial communication with the word “Mayday,” preferably repeated three times. For an Urgency condition, the word “Pan‐Pan” should be used in the same manner. If the words “Mayday” or “Pan-Pan” are not used but you believe an emergency or an urgent situation exists, handle it as though it were an emergency.

[@dougnixon6464]

if the pilot started by saying Mayday first thing, he wouldn't have had to subtle ask ATC to hurry up for a return heading "ahhhh, so can we expect to come back on 6s or 7s?" LOL

[@AirTrafficVisualised]

It's quite peculiar, American (that is the country, not the airline) crews seem very reticent to use the word "mayday", much preferring the nomenclature "we'd like to declare an emergency". Crews in other parts of the world (including similar Anglophone countries like the UK and Australia) exhibit no such reluctance - if you look at this video in Australia, the crew immediately declare a mayday: kzbin.info/www/bejne/h6KUeJSElJaVY5Y I'd be interested to hear from pilots what they think the difference might be.

[@blusheep2]

"APU" = Auxillary Power Unit, and is primarily used for electrical power on the ground and bleed air for starting the engines. All modern airline jets have them. Sometimes they break and are deferred until they can be fixed, which is what Tom's Travels is talking about. There are other ways to start the engine on the ground.

[@clarabarton8350]

All's well that ends well but if the outcome was different the question would have been why didn't the pilot or ATC suggest landing at Naval Air Station Fort Mugu. ATC should transfer every emergency to a dedicated person trained in CRM.

[@HEDGE1011]

Why? If there’s an onboard fire or some such sure, but why would you go to an unfamiliar field at night that you likely don’t have charts for and is probably not in the aircraft database? Was Mugu open? What was their CFR status? Why not just go back to LAX which has multiple runways, all the CFR, the pilots are familiar with it, and they have support there?

What website for aircraft tracking is that?

[@AirTrafficVisualised]

The radar display runs in custom software.

How does their aircraft not have an APU, is that optional on the 767?

[@AirTrafficVisualised]

Not optional, but in this case the APU was inoperative. Not all parts of a plane must necessarily be operational for it to fly - some are non-essential for short periods. Manufacturers will specify in a document called MMEL (Master Minimum Equipment List) which components can be INOP and how long after a failure the aircraft is allowed to be operated for before the fault must be repaired.

So THAT'S why my package was delayed!

Couldn't they land at the Naval Air Station? They were right there.

[@microdesigns2000]

There's more to prime, a truckload more.

[@hgbugalou]

No worries mate, you still have the RAT. 😂
