The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he returned to the airport after a local flight to practice three-point landings in his tailwheel equipped airplane. Upon touchdown, the aircraft veered to the right and the left wing began to dip. The pilot then applied "too much brake[s]" and the aircraft subsequently nosed over, coming to rest inverted. The pilot reported no mechanical failures or malfunctions with the aircraft prior to the accident.
