Probable cause
The failure of the intake valve. The soft terrain contributed to this accident.
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
Shortly after departing a privately owned airstrip the airplane experienced a rough running engine followed by a loss of power. The pilot executed a landing in a cultivated open field. The airplane nosed over when the main wheels dug into the soft terrain. Examination of the engine disclosed that an intake valve fractured.
