Heber Valley Airport
Aircraft Accident/Incident Report

Heber City, Utah 84032
Saturday, August 21, 1999 20:20 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said approaching dusk reduced visibility, and he decided not to continue his trip. He landed at Heber Valley Airport. As he applied brakes, the airplane veered to the right. The left wing struck the runway, and the airplane ground looped. A trail of brake fluid was found on the runway. The left brake line had separated from the caliper assembly. The threads were stripped out. There was no loop, or slack, in the brake line. The airplane had brake work done a year before the accident.

NTSB Probable Cause Narrative

The stripped threads and subsequent separation of the left hydraulic brake line leading to fluid loss and the pilot's inability to maintain directional control.
