NTSB narrative
The pilot stated that after takeoff the flight proceeded to a location called the "Villages" then he made a right turn and elected to return to the departure airport. He reported that he was on the west side of Lake Griffin and approximately 3 miles from the destination airport when the engine began to run rough. He reduced throttle control but the engine continued to run rough. He checked the magnetos and verified the mixture control was full rich which had no effect. He discontinued the approach and began a right descending turn not wanting to fly over the lake. He noted that something inside the engine compartment hit the engine cowling, and he looked for a place to land. He banked to the right and after spotting an opening, he lowered the flaps but overshot the intended landing area. While descending he noted a telephone pole straight ahead and applied left rudder to avoid the pole but the right wing collided with the pole. The head of the No. 4 cylinder separated from the barrel due to fatigue cracking. A review of the maintenance records revealed that the engine was overhauled on November 2, 1993. On June 1, 1999, the No. 4 cylinder was removed, repaired, and installed. The No. 4 cylinder had accumulated 1,076.9 hours since installation after repair.
Probable cause
The fatigue failure of the No. 4 cylinder resulting in a loss of engine power and subsequent forced landing.

- 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.
