NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
According to the pilot, during the landing roll in the experimental tailwheel airplane, the airplane drifted to the right slowly into a grassy area and struck a drainage ditch. The pilot stated that he applied left brake to correct for the drift, but was unsuccessful. After the accident, the airplane was placed on jacks to allow the left main wheel assembly to be rotated. The right brake line was capped off and the brake system was serviced. Once the preparation was complete, the left wheel was rotated by hand. When pressure was applied to the left brake pedal, the left wheel stopped rotating. Additional pressure was applied in an attempt to move the left wheel, with no success. The left brake functioned properly during the test and no other preimpact anomalies were noted. The winds were recorded as calm about the time of the accident.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot’s failure to maintain directional control during landing. Full narrative available
