NTSB narrative
The pilot reported that, while performing touch-and-go landings, on final approach with the carburetor heat on, the airplane’s engine suddenly lost total power. After assessing that the airplane had insufficient altitude to glide to the runway, the pilot selected nearby hay flats as a forced landing site. During the forced landing, the right main landing gear collapsed, and the airplane’s right wing impacted terrain, resulting in substantial damage to the fuselage and right wing. A postaccident examination of the engine, including the carburetor heat control, revealed no evidence of any preimpact mechanical malfunction or failure that would have precluded normal operation. Fuel was recovered from both wing fuel tanks and the fuselage sump drains. Although the atmospheric conditions in which the airplane was operating were conducive to the formation of carburetor icing at glide and cruise power settings, the pilot’s reported use of carburetor heat during the approach would have prevented the accumulation of carburetor ice. Based on this information, the reason for the loss of engine power could not be determined.
Probable cause
A total loss of engine power 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: local date, investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2025-02-21.
