Aircraft Accident/Incident Report

Talkeetna, Alaska 99676
Sunday, May 5, 1996 9:30 AKD

NTSB Narrative Summary Released at Completion of Accident

The pilot was in cruise flight on a personal flight when he noted a rise in the rear cylinder head temperature of the number two (rear) cylinder. He adjusted the mixture screw and watched the temperature continue to rise. During a precautionary landing, the engine stopped producing power, and the pilot was forced to land the airplane on a road. Subsequent examination showed that the piston in the rear cylinder would not move. Examination of the mixture screws showed that the mixture screw controlling the rear cylinder was in the lean position. The direction on rotation for leaning or enriching the mixture was not marked on the mixture screws.

NTSB Probable Cause Narrative

The pilot's failure to properly use the mixture control to enrich the fuel mixture, and the seizure of the piston in the cylinder.
