I'd like to see some expert comment on the nature of the "hum" caused by loose aileron hinge. How dangerous is such a vibration, and what should be done in addition to repairing the hinge.
Thanks

I think it had something to do with air flowing over the flap, cause it would seem to come and go with different flap settings from "in trail" to total reflex of an inch and a quarter or so.. Of course, it could have been the flap vibrating, but the hinge was easy and was done first,end of hum ... Don Skeele A&P
