Challis Airport
Aircraft Accident/Incident Report

Challis, Idaho 83226
Thursday, July 25, 2013 12:00 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during the takeoff roll to the south he became distracted by a helicopter operation at the south end of the airport. It was about this time that he noticed the airplane yaw, which he over corrected for. The airplane subsequently departed the right side of the runway, then swerved back to the left. The right wing and right elevator impacted the ground and were substantially damaged. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control during the takeoff roll.
