I am kind of wondering if this was similar to Transair flight 810, where the crew inadvertently shut down the good engine. Or possibly killed both engines on the go-around, leaving them dead stick or nearly that for the eventual landing.

Another possibility, just throwing it out there, that the cockpit also took a bird strike causing damage to the overhead panel which could have killed power to all kinds of stuff that wouldn't normally have been affected.

My tag line came from a quote about that incident.

Dan Gryder, POA's favorite, thinks the pilots pulled a fire handle. That apparently severs all fuel and electric connections to the engine, including the generator. I don't know how that extrapolates to both engines, unless both fire handles were pulled.

Trips the generator field relay, closes pylon firewall valves for the fuel, hydraulics, and pneumatics. Arms the fire extinguisher bottles to fire to that engine.

The fire handles are normally latched. The latch is removed if a fire is being detected for the associated engine/apu. The latch can be overridden with a release that is difficult to operate with a single hand. Pulling a fire handle is NOT a memory item on the engine fire, severe damage, separation checklist. It is a couple of steps into the checklist after the memory items. Confirmation from both pilots is required prior to pulling the handle.

I'm on the edge of my seat on this one. Can't wait for a definitive answer.

Dont hold your breath and dont be surprised if it’s ruled pilot error

Uh, Dan, if both fire handles were pulled at the instant of ADS-B, CVR, and DFDR failure, how did the aircraft manage four more minutes of flight and a teardrop reversal return to the runway?

superb energy management?

Probably not four minutes unless a plane drops like a rock down a well. Something a little less. Hard to say what switches were pulled or not pulled at this point, but dual fire bottles could explain some but not all. Pilot panic/loss of situational awareness looks like it could explain a bit too. We’ll see…

Really? Sure is for us. Requires confirmation from the other pilot, but still a memory item. Was the same on the 777 when I flew it.

In a very few years I’ve seen that change three times… in the same company.

I’ve also flown the same jet for two different companies where it was and wasn’t.

That sort of inconsistency makes mistakes related to their use even more suspect.
