So flaps stopped working, called my mechanic , and he said to check the rubber roller in the flap motor, it was stuck. Moved it by hand got it un stuck and flaps work fine now. Has anyone have this happened with their Cessna? The fix was to easy and cheap to make me confident. According to my mechanic probable a tall passenger bump the area below the flap lever and hit the switch.(I did have a tall passenger 2 days ago). Is this theory ok? What caused this if it was bumped what happened?
