Aircraft Accident/Incident Report

Fairbanks, Alaska 99709
Thursday, September 18, 2003 9:30 AKD

NTSB Narrative Summary Released at Completion of Accident

The commercial certificated pilot/aviation mechanic was landing on a remote ridge on a positioning flight to pick up a passenger for an air taxi flight. The gravel covered ridge was about 3,973 feet msl, and was covered by about 1 to 2 inches of snow. After a soft field landing touchdown, the nose gear collapsed during the landing roll, and the propeller struck the ground. The pilot indicated that he believed the bolt attaching the nose wheel fork to the nose gear strut failed, allowing the nose wheel to separate from the lower end of the gear strut. A postaccident inspection of the nose gear and its support structure revealed that the nose wheel strut drag link was torn from its aft attach point. The keel bulkhead at the drag link attach point received tearing and shearing of the rivets and deformation.

NTSB Probable Cause Narrative

A failure of an attaching bolt that allowed the nose wheel fork to separate from the nose gear strut, which resulted in the collapse of the nose gear during the landing roll. A factor contributing to the accident was rough/uneven terrain.
