For any GSP Transall owners, I had something happen today that might be worth checking over. During my second flight, The aircraft started yawing to the right-slightly at first, but got progressively worse as the flight continued. I suspected an engine sagging, but that was not the case. By the time I set up for final approach, I was holding left aileron and rudder to keep it straight. Turns out that the Right servo tray had disconnected itsef from the wing and was hanging out of the plane, held only by one last screw. This plastic "door" should probably have some thin ply laminated to the back of it or be completely replaced. Haven't dug into mine yet, don't know what I'll do. Just thought some others should know of this. Might save a plane.
