What happened
The student pilot was conducting a solo cross-country flight when the aircraft's engine ceased to function while the plane was in cruise flight. With no power available, the pilot initiated an emergency landing procedure. The aircraft touched down in a remote and swampy area, which complicated the stopping process. The impact forces caused the nose of the aircraft to overturn upon coming to rest.
The investigation
Following the accident, investigators examined the engine to determine the cause of the sudden power loss. The inspection revealed that the number three connecting rod had failed completely. This mechanical failure was consistent with the reported engine failure during flight. Records indicated that the engine had accumulated a total of 2,455 flight hours and had been 1,752 hours since its last major overhaul.
Findings
The primary factor leading to the accident was the mechanical failure of the connecting rod. This internal engine component failure resulted in an involuntary emergency landing. The remote and swampy nature of the landing site contributed to the severity of the ground damage, specifically the nose-over condition.
