Aircraft Accident/Incident Report

Aurora, Colorado 80137
Sunday, November 22, 1998 13:30 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot landed on runway 32 (4,687 ft. X 38 ft., asphalt) with a right 'gusty' crosswind. After touch down, the tail wheel began to 'shimmy.' The pilot said he pushed the control stick forward to relieve pressure on the tail wheel. He said a gust of wind then caused the airplane and weather vane sharply to the right. The airplane collided with terrain and nosed over.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control. Factors were the gusty crosswind and terrain.
