Probable cause

The landing gear collapse for undetermined reasons.

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.
