NTSB narrative
As the airplane was climbing from the airport, the engine lost total power. The pilot performed a forced landing to a wooded area, where the airplane collided with trees, and subsequently descended to the ground. Examination of the engine revealed that the number four cylinder had separated at the mid-point on the barrel. Examination of the cylinder revealed that the barrel failed due to fatigue, which originated from a corrosion pit. The engine was overhauled in September 1994, which included the installation of the number four cylinder. The engine had accumulated about 800 hours of total operation since the overhaul.
Probable cause
The failure of the number four cylinder barrel due to fatigue which originated from a corrosion pit at the base of a cooling fin.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
