As always, some good reading in the accident docket.
From the CVR, sounds like the FO maybe pushed the override button to unlatch the right fire handle a couple of times but didn't immediately twist the handle after pulling it. The handle would have been unlatched anyway in this situation since they had a fire warning. The captain caught the error, good crosscheck.
They never got to the first item on the Engine Fire, Severe Damage or Separation checklist but on the ground the fire handles and fuel cutoffs are all that mattered in this case and they are on the evac checklist. Still, I'm sure the feds will gig them for not following the challenge and response cadence of the emergency checklists more closely while on fire.
Over the years the number of memory items on the engine fire and evac checklists has dropped to zero on the Boeing twins. Will some of the memory items come back for a more rapid shutdown and evac perhaps? Would it have made a difference in this case?
The flight attendant interviews seem to repeatedly ask why they didn't bring their flashlight off the aircraft for a daytime fire evac.
A couple of questions involved the service dog, er, I meant to say the emotional support animal that apparently was evacuated successfully.
