NTSB narrative

The landing gear collapsed during a precautionary landing following a complete electrical system failure. The airplane experienced a complete electrical failure during cruise. The pilot decided to make a precautionary landing and diverted to an alternate airport. He shut down all electrical items when he became aware of the electrical system failure. As he neared the alternate airport, he slowed the airplane down to the normal gear extension speed, lowered the gear with the automatic switch, and felt the landing gear extend. He stated that because there were no landing gear lights illuminated he could not verify that the landing gear was in the locked position. He then conducted the emergency gear extension checklist, and noted that his airspeed and power were consistent with what he associated with the landing gear being in the down position. Touchdown was normal, but on the landing rollout, the nose and left main landing gear collapsed and the left wing struck a taxi light. Prior to exiting the airplane, the pilot shutoff the master switch. During the recovery of the airplane, it was raised on jacks and the landing gear was extended with no discrepancies noted. During repair work on the airplane, a landing gear extension/retraction test was conducted, with no system anomalies noted. The inspection of the airplane was unable to determine the cause of the electrical failure.

Probable cause

The failure of the landing gear for undetermined reasons to go into the locked position after the pilot conducted a manual and emergency gear extension. A factor in the accident was the undetermined failure of the electrical system.

  • 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. Values present in the bulk record are kept.
