NTSB narrative
The pilot reported that while in cruise flight, he noticed that his heavy keychain was pulling the key out of the ignition switch. He reached down to push the key back in, but inadvertently moved the key to the off position due to the thick glove on his hand, which resulted in a loss of engine power. When he attempted to reinsert the key and restart the engine, the key broke inside the ignition switch. He was unable to use the broken key to restart the engine. During the forced landing, the airplane sustained substantial damage to the right wing. The pilot reported that there were no other mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot inadvertently moved the ignition key to the off position and broke the key, which resulted in a loss of engine power and subsequent forced landing.

Source notes (4)
- 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.
