NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

One month prior to the accident the pilot had noted a leak in the right brake line. Upon inspection he found a small hole in the line. The line was replaced and the airplane was taxi, takeoff, and landing tested for brake airworthiness. No further discrepancies were noted. The pilot noted no difficulties with approach, initial touchdown, or the initial landing roll. Approximately midfield, after the airplane had slowed down, he applied brakes. The right brake did not activate properly, and the airplane veered off the left side of the runway, encountered a muddy field and nosed over. Witnesses to the accident stated that it was windy at traffic pattern altitude; however, surface winds were about 5 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The owner/builder's failure to properly bleed the brake system following replacement of the right brake line, which caused the right brake to not function and led to the pilot's inability to maintain directional control.
