Accident Details
The accident occurred when the aircraft was climbing out after its second touch-and-go landing. Witnesses reported hearing popping noises coming from the engine. Subsequently, the aircraft nosed down, descended, and crashed into a wooded area approximately 1,000 feet past the departure end of the runway.
Witness Observations
Multiple witnesses on the ground heard distinct popping sounds emanating from the engine shortly after the aircraft began its climb. They then observed the nose drop and the aircraft descend rapidly before impact with trees.
Investigation Findings
Post-accident examination of the engine revealed a compression test reading of 17/80 for the #2 cylinder. Further inspection showed that the exhaust valve guide and seat were misaligned. Additionally, all intake connector hoses on the engine were found to be dry-rotted. The spark plugs appeared to be gapped too tightly, and one ignition lead was not properly installed.
Maintenance History
The most recent annual inspection had been completed approximately one week before the accident. The aircraft had accumulated about 15 hours of operation since that inspection.
