Aircraft Accident/Incident Report

Aspen, Colorado 81611
Wednesday, August 11, 2010 11:15 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was taking off on runway 33. As the tail started coming off the ground, the plane veered off to the left and "accelerated into a typical ground loop." After the accident, four witnesses approached the pilot and told him that right after he added power, the wind sock swung around into a 90-degree crosswind and that a strong gust moved across the field. The pilot said that age was slowly "having its effect," and was slowing his reaction time.

NTSB Probable Cause Narrative

The pilot's failure to maintain directional control during takeoff in gusting crosswind conditions.
