Aircraft Accident/Incident Report

Springfield, Ohio 45501

NTSB Narrative Summary Released at Completion of Accident

The airplane had undergone a 100-hour inspection during which the number 3 cylinder was replaced. During the first flight after maintenance was performed, while en route to the destination airport, the airplane experienced a partial loss of power. The pilot prepared for a precautionary landing at a nearby airport; however, while en route to the airport, the pilot realized he would not be able to make it to the runway, and performed a forced landing on a football field. Examination of the engine by a Federal Aviation Administration (FAA) inspector revealed the number 3 cylinder exhaust rocker arm set screw had backed out and the jam nut was observed lying in the rocker cover. Additionally, the "1102" plug was missing from the intake port of the number three cylinder. A measurement was taken of the tappet clearance (between the rocker foot and the valve stem tip) and noted to be .300 inch. According to published Lycoming Service Instructions, the tappet clearance should have been .006 to .012 inch.

NTSB Probable Cause Narrative

Inadequate installation of the number 3 cylinder.
