Probable cause
A loss of engine power due to the failure of the master rod to the number one cylinder resulting from a lack of oil.
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 agricultural aircraft experienced a loss of engine power and collided with the terrain during a spraying operation. An external examination of the engine revealed that the master rod to the number 1 cylinder had failed. Also noted was a lack of oil in the engine oil sump. No other discrepancies were noted.
