On November 23, 2003 at about 8:00 pm local time, a Piper PA-22-135, registered N8982C, was substantially damaged in an accident near Emmett, Idaho (Emmett Municipal airport). It was a personal flight under general aviation rules (Part 91). No one was hurt; 2 people were on board or involved. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

Brake failure as a result of inadequate hydraulic (brake) fluid in the aircraft's closed brake system. Contributing factors were the pilot's overall lack of experience in the aircraft make/model, the cold soaked brake system due to the low temperatures, and the embankment and ditch.

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

The 118 hour pilot had less than 16 hours in the make/model, and the aircraft was equipped with a closed hydraulic brake system which was temperature sensitive. The pilot departed on a local flight, flew two touch and go landings and then climbed out to a higher (cooler) altitude before returning to the airfield for a full stop landing. During the landing roll the pilot was unable to achieve braking and the aircraft rolled off the upwind end of the runway, down an embankment and into a ditch. A significant drop in temperature had taken place over the previous several days to the flight and, according to a pilot/mechanic with 40 years of experience in the make/model, the aircraft's braking system would become ineffective if the system had less than optimal amount of hydraulic fluid and was then subjected to a significant cold soaking. Post-crash examination of the brakes by an FAA inspector revealed no mechanical malfunction, however the examination was conducted in a heated hangar.
