Subject: Flap and Aileron Hinge Pocket Cover Plates

Recently a Bearhawk 4-place had a flap retraction problem on one flap because the pocket cover plate jammed into the top wing skin, and would not allow the flap to retract. The plane was still flyable, but this problem needs to be addressed.

FLAPS: On the top of the flaps the cover plate should only be deep enough to cover the gap from the flap spar to the back of the wing skin, about 1 inches, with the flap up. AILERONS: On the aileron the cover needs to be much deeper, so that with full down aileron, the front of the cover is still under the wing skin. Robert Barrows 9/1/15
