aviation accident: Grumman American AA-5A near SCOTT (1998-10-29)
Probable cause: The disengagement of the crankshaft gear due to the maintenance personnel not installing the gear lockplate at the last engine overhaul, resulting in the loosening of the gear retaining bolt, and the subsequent fracture of the gear alignment dowel. A factor was the pilot's inadvertent stalling of the aircraft during the forced landing.
