Probable cause
The loss of directional control on the ground caused by the failure of the left brake disc. Contributing to the accident was the pilot-in-command's intentional ground loop of the airplane.
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 landing, the pilot-in-command lost the effectiveness of his left brake. He elected to ground loop the airplane rather than run off into the tundra. Examination of the left brake assembly revealed that the brake disc had separated from the assembly.
