Primary finding
Probable cause
The pilot’s failure to maintain clearance from an object during takeoff, which resulted in a collision and ground loop. Contributing was the pilot’s selection of an unsuitable takeoff area.
Investigator assessment
Analysis narrative
The pilot reported that, during the takeoff roll while departing from a remote ridgeline in a tailwheel-equipped airplane, the airplane’s left wing struck a small pine tree. The airplane subsequently ground looped to the left, which resulted in substantial damage to the right wing and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
