The NTSB's narrative final · quoted from the NTSB record
The pilot in the tailwheel equipped airplane reported that, he made a normal approach and landed a little fast about 1/3 of the way down the grass airstrip. As he reached the last 1/3 of the airstrip, he got nervous and applied the brakes hard. The airplane subsequently nosed over and came to rest inverted substantially damaging the vertical stabilizer and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
