All of the above and Stupid Pilot snags.........
As in the description of the fault beggars belief......
you get things like engine U/S (piston)............... I have had that one
turns out it misfired once and had never done it again..
Or another one flaps stuck down............ check plane and they are up. asks and get the reply ohh we had a play on the ground and got them to go up........ they work now,
so whichever microswitch that was sticking and causing the problem is now no longer traceable...
