Grand Junction, Colorado 81526
Wednesday, November 6, 2002 14:00 MST

NTSB Narrative Summary Released at Completion of Accident

On the return flight, approximately 35 miles from the destination airport, the airplane's alternator failed and all electrical power was lost. Attempts to restore electrical power were unsuccessful. The pilot used his cell phone to call the airport's tower and was given clearance to land. He followed the airplane's emergency checklist to manually extend the landing gear and landed the airplane. During the landing roll, the airplane's left main landing gear collapsed, the airplane veered off the runway and struck a taxiway sign. The airplane sustained substantial damage to its left wing.

NTSB Probable Cause Narrative

the collapse of the left main landing gear during landing roll resulting in loss of control/ground loop/swerve and subsequent impact with a sign. Contributing factors include, the airplane's total loss of electrical power due to an alternator failure and the inoperative landing gear indicating system.
