The NTSB's narrative final · quoted from the NTSB record

The pilot's landing on runway 19 was normal and the wind was calm. During landing roll, the aircraft departed the runway to the right, traveled down a 10 degree embankment and struck a fence. The pilot said he applied left rudder pressure without effect. According to an FAA inspector who interviewed the pilot following the accident, the pilot told him that he may have inadvertently applied pressure to the rudder pedal rather than to the brake. A functional test of the rudder and brake system was performed and no discrepancies were noted. The pilot had accumulated a total of 7 hours in the PA-18-150, 2 of which were as pilot-in-command. He had received his tailwheel endorsement on the day of the accident.
