ConditionsVMC
OperationFAR 121
Probable Cause
The fatigue failure of multiple hinge ribs associated with the right outboard aileron, which resulted in abnormal aileron movement and airframe vibration. Contributing to the failure was the mis-rigged condition of the right outboard aileron, which increased operational loads on the hinge fittings during cruise flight.
