Probable cause
The separation of the number 1 cylinder and remedial action by the PIC not possible. A factor contributing to the accident was: rough/uneven terrain.
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
During a spray run the number 1 cylinder head separated and a total power loss followed. No pre existing crack was reported at the point of failure. The pilot set up for a forced landing in hilly, uneven terrain and during the landing roll the aircraft momentarily became airborne after cresting a hill and then pancaked into the ground.
