NTSB narrative
According to the flight instructor, while on final approach to the runway the engine experienced a loss of power, and he executed a forced landing to a wooded area near the airport perimeter. The airplane impacted trees which resulted in substantial damage to both wings, the fuselage, and the stabilator. Postaccident examination of the airplane’s exhaust system revealed that a steel baffle of the muffler flame tube assembly had failed and blocked at least 95% of the single exhaust outlet port (tailpipe). Deformation damage was noted to the remaining flame tube and the steel baffle which indicated that the failure had been present for an unknown period of time before eventually blocking the exhaust path. There were no other mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
The loss of engine power due to a failed muffler flame tube assembly which resulted in an exhaust blockage.

- 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, cause areas. 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.
