Amateur-built CULPS SPECL SOPWITH N329CC accident near Pottstown, Pennsylvania

Probable cause

The pilot’s failure to maintain directional control during landing, which resulted in a ground loop.

NTSB analysis

The pilot reported that he recently purchased the experimental, amateur-built, free-castering tailwheel airplane. He had completed nine takeoffs and landings uneventfully on the day of the accident. During the tenth landing, as the tail touched down, the airplane turned left. The pilot tried to correct with full right rudder and right brake application; however, the airplane continued to travel left, and ground looped on the runway, resulting in substantial damage to the left wing. Examination of the wreckage by a mechanic did not reveal any preimpact mechanical malfunctions, nor did the pilot report any.
