Probable cause
The fracture of the aileron hinge strap due to fatigue crack propagation, which resulted in substantial damage to a wing rib aft of the spar at the outboard aileron cutout. Contributing to the accident was inadequate maintenance inspection.

Read the full NTSB narrative
About 5 minutes after taking off, the pilot observed that the left upper aileron had come loose from the inboard hinge. The pilot returned to the departure airport and landed uneventfully. A postaccident examination of the airplane revealed that a wing rib aft of the spar at the outboard aileron cutout was substantially damaged. Examination of the aileron hinge strap fracture surfaces revealed crack arrest marks and thumbnail-shaped patterns on the fracture surfaces, which emanated from both the top and bottom surfaces of the hinge strap. The fracture surfaces were consistent with asymmetric reverse-bending fatigue crack propagation. The fatigue cracking propagated from the top and bottom surfaces through almost the entire cross-section of the hinge strap. The pilot reported that while there were no inspection criteria from the manufacturer relative to the hinge straps, all hinge straps were inspected as part of each annual inspection.
