NTSB narrative
The pilot of a powered glider reported that, after the engine had been shut down and the propeller stowed, he encountered more downdrafts?than expected. The glider did not have sufficient altitude to reach the airport or to re-deploy the engine. During the forced landing on rough terrain, a wing impacted vegetation and ground looped, resulting in substantial damage to the fuselage and empennage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the powered glider that would have precluded normal operation.
Probable cause
The glider’s encounter with atmospheric conditions where the lift was not sufficient to maintain?flight.

- 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.
