Casualties unknown

Landing gear collapse following electrical system failure (N8967P)

Grand Junction, CO, US

On July 8, 1993, a Piper PA-24-260 (registration N8967P) was involved in an aviation accident near Grand Junction, CO. Investigators recorded the probable cause as: Electrical system failure resulting in loss of gear indication, which contributed to the pilot's inability to verify gear position and subsequent collapse of the landing gear during landing roll. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

Electrical system failure during cross-country flight left pilot without gear indication lights, leading to a collapsed landing gear upon touchdown.

What happened

During a cross-country flight, the aircraft experienced a complete failure of its electrical system. This malfunction prevented the cockpit from providing visual confirmation of the landing gear status via standard indicator lights when the pilot lowered the gear. Although the pilot assessed that the manual extension mechanism appeared to be in the correct position for the gear to be down and locked, the lack of positive indication remained unresolved.

During the subsequent landing roll, the pilot struggled significantly with maintaining directional control of the aircraft. The situation deteriorated rapidly as the landing gear collapsed upon impact with the runway surface, causing substantial damage to the airframe.

The investigation

The examination focused on the sequence of events surrounding the electrical failure and the mechanical state of the landing gear. Investigators noted that while the manual system seemed properly engaged, the absence of electrical power eliminated standard verification methods for the crew.

Probable cause

Electrical system failure resulting in loss of gear indication, which contributed to the pilot's inability to verify gear position and subsequent collapse of the landing gear during landing roll.
