Sasless,
The guy that tipped me off about walking away a bit for another look was a fixed wing pilot who once completed a full detailed walk around on a cabin size piston twin, all was good, walked to the nose, away ten steps and again looked her over from wingtip to wingtip and noticed that there was a non symmetrical flap condition between the wings. The flaps on one side had locked in place in about the take off postion and the other side were somehow retracted normally. Would have pretty been nasty after take off when he went to reel in the extended flap I would think.
The problem was not obvious from up close but was pretty evident from the front on view. It only takes a few extra seconds.
cheers
Vic
