Probable cause
A seized engine exhaust valve. Factors include rough terrain and a collapsed nose gear.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The student pilot of the Cessna 150 elected to make an emergency landing in an open field, when she lost partial power, and experienced severe vibrations. After touchdown on the rough terrain, the nose gear collapsed and the aircraft nosed over. Later investigation revealed that an exhaust valve was seized in its guide, and was stuck in the open position.
