Hi JammedStab,
The part we're trying to figure out is actually the flap actuator, which is the second image on page 29. It's the part attached to the elevator in the back that lifts it up or retracts it, etc. The image of the actuator underwater doesn't really show it in its entirety. The investigators found the actuator in the flaps retracted position, so somehow I have to figure out how that part would look - on its own - in the retracted position and the takeoff position.
Thanks for any help you might be able to provide!
