Accident Sequence
The pilot reported that after touchdown on the runway, the left brake failed, resulting in a loss of directional control. The aircraft subsequently veered off the runway and collided with a barbed wire fence.
Post-Accident Examination
An individual holding an FAA airframe and powerplant mechanics certificate, who was present at the airport at the time of the accident and works for an aircraft wreckage retrieval firm, examined the brake system within 10 minutes of the accident at the direction of the Safety Board. He reported that the left brake disk was cold to the touch, while the right disk was hot. The left brake pedal was stiff and would not move when pressure was applied, and the corresponding left brake calipers would not move.
Subsequent Actions
The aircraft owner moved the aircraft and repaired it before the brake system could be examined in detail.
