Probable cause
Failure of the no.7 cylinder head which led to a forced landing and substantial damage to the aircraft when it nosed over after colliding with a ditch.
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 pilot experienced a loss of engine power during an aerial application flight. The aircraft struck a ditch while attempting to land on a road and nosed over onto its back. Examination of engine revealed that the no.7 cylinder had cracked across the top of the cylinder head.
