LATAM B773 complete electrical failure?
Incident: LATAM B773 near Belo Horizonte on Dec 20th 2018, electrical failures
Surprised this isn't a hot topic - I must not understand the situation correctly. |
CESSNA MODE
Looks like they reverted to basic Night VFR Cessna mode. Put the gear and flaps down, and plopped it onto a suitable runway. Everyone OK and aircraft reusable.
Good Job! |
I’m surprised too. Or not...
;)...maybe a complete electrical failure is something that happen very often on a modern widebody like the 777-300 ER... People are not very excited about it. After all it wasn’t a BA or Qantas 777 ;) Surprised this isn't a hot topic - I must not understand the situation correctly.[/QUOTE] |
ipad arrival anyone? ;)

AV Herald report on B777-300ER diversion
Incident: LATAM B773 near Belo Horizonte on Dec 20th 2018, electrical failures, RAT deployed Read all about it here. |
Looks like the ATC comms got patched by mistake onto the PA and went out in the cabin, hence the pax knew that they were in deep Doodoo. Either way an outstanding bit of airmanship from these guys. If this had happened mid Atlantic then we’d be looking at another MH370, no? |
Azul Linhas Aereas ATR-72-212A registrations PR-AKJ and PR-AKD have been dispatched to take about 7 tons of equipment, including the needed hydraulic jack and replacement tyres, to Belo Horizonte. The MH370 people will, no doubt, be looking at this with deep interest. |
"The MH370 people will, no doubt, be looking at this with deep interest."
Key Operative line is that the captain kept communicating with ATC on the one remaining radio..... |
The other issue is how it was reported here in Brazil, a company spokesman / very senior manager / exec said (I'll find the original quote in Portuguese later, so translating from memory)
"I have spoken to the cabin crew of this flight, one member told me that this was a miracle and without faith and God, we would all certainly be dead" A very interesting stance for the company to take. By interesting... I think I mean "ridiculous". What are people's thoughts on this? |

It certainly will be interesting to know what electrics they had left and what caused this. Aircraft like this have considerable levels of automatic electrical fault isolation and huge redundancy that only multiple failures can cripple. However, as some of us appreciate, when **** happens....
Good to see a safe landing! :) |

This is doing the rounds already in Brazil... Whatever was wrong, was no small thing

A serious glitch indeed, wonder if the preceding faults had any connection to this. |
That pdf link from JumpJumpJump really is worth looking at.

It is indeed worth looking at ...
Looks like a freaking nightmare. Well done guys !!! |
Agreed - this is beyond scary.
But after the recent posts lamenting the loss of traditional pilot skills, this is a wonderful testimony to a very competent crew. |
Like very many of the other comments regarding this incident, my opinion, is that it was a serious situation & was certainly very well handled by the Crew.

Update from AvHerald
Updated description of the electrical failures
On Dec 22nd 2018 The Aviation Herald learned that the electrical problems started with the failure of the right hand backup generator, as result both transfer and both converter circuit breakers popped leaving all electrical busses unpowered although left and right main generators as well as their generator controls, the APU and the left backup generator remained operative (see ELEC page below, the lines to the L MAIN and R MAIN should be green not white and these symbols should be green, too). As result almost all systems except a few connected to the standby busses lost power, only systems remaining powered are: stand by busses (powering one VHF radio) and emergency lighting, the left inboard and outboard and upper center displays as well as the left CDU remain also powered (according to FCOM via the batteries and/or RAT - with the RAT operating also the right hand - first officer's - displays are being powered). |
