Aircraft Accident/Incident Report

Dillon, Montana 59725
Monday, July 5, 2010 13:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during approach for runway 22 he observed the winds to be a quartering headwind from the right. After a normal approach the airplane touched down on the main landing gear. As the tail wheel was about to touch down the airplane veered to the right. The pilot used left rudder and brake to compensate for the turn, but the airplane exited the right side of the runway. Through the use of left rudder and brake the pilot was able to stop the right turn, but then the airplane turned to the left and ground looped. The airplane sustained substantial damage to the right wing spar and right elevator.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control during landing.
