NTSB narrative
The airplane collided with trees during an off airport forced landing following a loss of engine power. In cruise flight, the pilot selected 22 inches of manifold pressure and 2,200 revolutions per minute (rpm). As he descended, he reduced the manifold pressure to 16-17 inches, pulled the carburetor heat on, and left the rpm at 2,200. He was about 2 miles from the airport, and making a 45-degree entry to the downwind, which is the local approach to the runway. He had one notch of flaps selected. As he descended through 600 feet, the engine died. He raised the flaps after the engine quit producing power. He selected full down flaps about 20 feet above the trees. After the airplane came to rest, the pilot secured the master switch, magnetos, and fuel. The airplane was in a nose low position, and fuel flowed out of the vent. During a follow-up examination, the engine ran for several minutes during a test run with no discrepancies noted.
Probable cause
A loss of engine power during approach to land for undetermined reasons.

- 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.
