I am amazed how quickly the peanut gallery are talking about shutting down the wrong engine. There is NOTHING to suggest that the #1 engine was shut down by the crew IN FLIGHT. The engine #1 is clearly NOT in feather.
The fact that the condition level is in Feather/cut off but the blades are not indicates that it was done after the aircraft was on the ground. I think a pretty smart move if ur avoiding a subsequent fire.
Leave the conclusions to the accident board. They will have the FDR/CVR.
