Incident Overview
An aircraft being prepared for a ferry flight following an engine overhaul experienced a loss of directional control during taxi from a parking area. The pilot reported that the aircraft was located on rough sod and required full power to initiate movement. As the aircraft began moving, the pilot attempted to execute a right turn onto the taxiway. However, the right brake pedal was described as "locked in the no-brake position," and the rudder, which controls nosewheel steering, was not responsive.
Sequence of Events
After the attempt to turn, the aircraft continued across the taxiway and struck two parked aircraft. Witnesses reported that the "breakaway power" remained constant until after the collision. Subsequent examination of the brake system revealed no evidence of mechanical malfunction, although surface rust was present on the brake discs.
Post-Incident Findings
The exact cause of the brake pedal issue and steering unresponsiveness was not determined. The presence of surface rust on the brake discs was noted, but no other anomalies were found during the inspection. The aircraft and the two parked aircraft sustained damage, though the extent was not specified in the investigation report.
