Incident Overview
An aircraft executed an emergency landing after experiencing a jammed aileron control. The landing was accompanied by skidding before the aircraft came to rest in marshy terrain. The aircraft was subsequently moved to clear it from tidal water.
Pilot and Owner Accounts
The pilot, occupying the rear seat, and the owner, in the front seat, stated that after performing several steep turns, the aileron control became immovable. The aircraft adopted a left-wing-down attitude and was controlled using throttle, rudder, and elevator inputs. The aircraft skidded left until impact with the marshy terrain.
Post-Accident Inspection
During a later inspection by a mechanic, a wrench was discovered in the fuselage. While the wrench was suspected to have caused the jam, it could not be positively identified as the jamming device because the aircraft had been moved from its original position after the landing.
