Event Overview
A complete electrical failure occurred during the flight, according to a report from the airport manager. The pilot elected to return to the departure airport. The tower issued a landing clearance using light gun signals.
Landing Gear Operation
The pilot moved the landing gear handle to the down position in preparation for landing. The landing gear dropped from their bays but did not extend and lock into place. The pilot did not pump the emergency landing gear extension handle to lock the gear in the down position.
Touchdown and Damage
Upon touchdown on the runway, the main landing gear legs folded back into their retracted position. The left wing and horizontal stabilizer then contacted the runway surface. The aircraft came to a stop in an upright position. Substantial damage was sustained to the left horizontal stabilizer.
Investigation
The reason for the electrical failure was not determined.
