The airplane collided with the terrain and nosed over following a loss of brake pressure while taxiing for takeoff. He reported that the brakes did not work when he applied them to slow the airplane in order to turn around for takeoff after back taxiing on the runway. The airplane traveled off the side of the runway and continued downhill into a ditch where it rolled onto the right wing. The pilot stated that he applied the parking brake when the airplane was being fueled and the brakes worked properly at that time and when he performed the engine run-up. No brake fluid was found on the hangar floor where the airplane was kept, nor was there any found along the taxi route used by the airplane. The master brake cylinder was disassembled and appeared to be in working order with no leaks. The airplane was placarded in accordance with Airworthiness Directive 85-02-05 R1. The placard states, "NO BRAKING WILL OCCUR IF AIRCRAFT BRAKES ARE APPLIED WHILE PARKING BRAKE HANDLE IS PULLED AND HELD."
Probable Cause: The normal brake system was inoperative due to undetermined reasons. A factor associated with the accident was the ditch that the airplane encountered.
