Event Location
Probable Cause
The pilot's failure to maintain directional control during the landing roll, which resulted in a ground loop.
Full Narrative
The pilot stated that while landing, the airplane started diverting to the right. He corrected with full left rudder, but the airplane did not respond. He then applied full left brake, which caused an over correction. The airplane ground looped to the left, and the right lower wing contacted the runway, damaging the lower right wing spar. The pilot stated that the airplane and engine had no mechanical failures or malfunctions that would have precluded normal operations.
