Probable cause

The brittle fracture of the left brake master cylinder tread end causing loss of directional control.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

During the landing roll, the aircrft veered to the right, off the runway. The aircraft struck the airport's tetrahedron, which was located adjacent to the runway. Inspection of the airplane found the left brake master cylinder had broken and lodged between the rudder pedal and the floor. This resulted in the loss of directional control and prevented the pilot from maintaining the aircraft's position on the runway.
