Aircraft Accident/Incident Report

Guymon, Oklahoma 73942
Thursday, February 26, 2009 12:45 CST

NTSB Narrative Summary Released at Completion of Accident

During takeoff, the experimental airplane's left main landing gear shock strut rod separated. During an emergency landing, the separated rod impaled the ground, which caused the airplane to nose over on the left wing and come to rest inverted. The airplane was equipped with 35-inch-wide tundra tires. According to the tire manufacturer, several operators of this make/model airplane are equipped with 31-inch-wide tundra tires and there have been no reported shock strut rod separations. The investigation could not determine why the rod separated.

NTSB Probable Cause Narrative

Failure of the left main landing gear shock/strut during takeoff for undetermined reasons.
