Witness Observations and Accident Sequence

Witnesses reported seeing black smoke trailing from the aircraft shortly after it lifted off and reached approximately 50 feet above the runway. Not long after, a loss of engine power occurred. The aircraft then descended and struck the ground in a nose-low attitude. The accident site was to the left of and near the departure end of Runway 14. The runway has a length of 2,700 feet and is surrounded by trees.

Post-Accident Examination

An examination of the aircraft disclosed two issues with the carburetor. A piece of the mounting gasket for the carburetor air filter was found lodged in the venturi section of the carburetor. This gasket was identified as a non-Cessna four-piece part. Additionally, the carburetor float was not buoyant, which resulted in engine fuel flooding. The aircraft was operating on automotive fuel at the time.
