Aircraft Accident/Incident Report

Jerome, Idaho 83338
Friday, September 10, 2010 15:45 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported he was landing his tail wheel-equipped airplane in almost direct crosswinds that were 11 knots, gusting to 18 knots. Soon after touchdown, he lost directional control. The airplane subsequently departed the side of the runway, and entered an area of grass covered soft terrain. As the airplane continued a left turn in the soft terrain, the right main landing gear collapsed inward due to an overload failure. The right wing contacted the surface and was substantially damaged. The pilot further stated the he did not believe there had been any anomalies associated with the airplane's flight control or tail wheel steering systems.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control during the landing roll in gusty crosswinds.
