NTSB narrative
The airplane's main landing gear collapsed during a precautionary landing following electrical problems. A witness reported that the main landing gear was not fully extended during the approach to the landing runway. The pilot stated that he lowered the landing gear handle and the extension sequence appeared normal except for the fact that at this point the electrical system appeared to be dead and no green 'gear down' light was observed. The alternator circuit breaker was found in the out position. A hand operated hydraulic pump is available in the aircraft for extension of the landing gear in the event of a hydraulic or electrical system failure. Post accident cycling of the landing gear revealed no anomalies.
Probable cause
the unlocked main landing gear and the manual gear extension not performed by the pilot. The electrical system failure was a contributing factor.

- 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. 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.
