Aircraft Accident/Incident Report

Sheridan, Arkansas 72150
Tuesady, May 19, 1998 19:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane collided with trees following an inadvertent engine start. The pilot stated that the tandem airplane was positioned on a taxiway with the right wheel chocked and his wife seated in the rear seat with her seatbelt fastened. The pilot attempted to start the engine by 'hand propping' several times, but was not successful. He thought that he had 'flooded' the engine and decided to clear the engine by turning the propeller again with the magento OFF, fuel valve CLOSED, and throttle FULL OPEN. The pilot thinks he mistakenly turned the magneto ON, which resulted in the engine starting when he began turning the propeller.

NTSB Probable Cause Narrative

The inadvertent engine start due to the pilot's failure to ensure that the magneto switch was in the OFF position when he was attempting to clear the flooded engine. A factor was the pilot's improper starting procedure, which resulted in flooding the engine.
