Probable cause
The failure of the nose landing gear to extend and lock due to the failure of the alternator and reduced battery power due to the cold ambient temperature, which prohibited the electrically-driven hydraulic pump from supplying adequate hydraulic pressure to extend the nose landing gear. The cause of the left main landing gear collapse could not be determined, as there were no postaccident anomalies or malfunctions found when the landing gear was actuated following replacement of the alternator and battery.
