NTSB narrative
After extending the landing gear, the pilot confirmed that the green landing gear light was illuminated, which indicated that the landing gear was down and extended. A short time later, a complete electrical failure occurred, and the landing gear collapsed during the landing roll. A postaccident examination of the airplane revealed that the landing gear was partially extended, the main landing gear struts were folded inboard, and the nose landing gear was folded up into the wheel well. All wiring to the landing gear motor, gear indicator and limit switches and control circuits were inspected and exhibited no anomalies. However, during the examination, wiring was found pinched and tangled in the left main landing gear actuating arm. It could not be determined if this wire contributed to the electrical failure or if it caused a possible false activation of the gear limit switches, which then falsely illuminated the landing gear light.
Probable cause
The landing gear collapse 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-07-03.
