Murtaugh Strip Airport
Aircraft Accident/Incident Report

Murtaugh, Idaho 83344
Thursday, September 2, 2010 9:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during landing he noticed the wind intensity was increasing at the private airstrip. He departed again for his fifth aerial application flight of the day. While on the takeoff, as the tail was lifting off the ground, a gust of wind struck the airplane and it veered towards the right. The airplane exited the runway surface and struck a power pole, substantially damaging the wings, fuselage and empennage. The nearest weather reporting station, located about 13 miles from the accident airstrip, reported wind at 13 knots gusting to 19 knots. The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine.

NTSB Probable Cause Narrative

The pilot’s inadequate compensation for the wind and failure to maintain directional control during the takeoff roll.
