What happened
The pilot reported that the left brake failed while rolling out on a runway measuring 3,200 feet in length. The landing was performed with a significant crosswind component, specifically a 20-degree right quartering tailwind of 10 knots. Concerned about running off the departure end of the runway and encountering a 50-foot dropoff, the pilot initiated a ground loop to the right to maintain directional control.
The investigation
Following the accident, investigators examined the main gear braking system for mechanical issues. The post-accident examination found no defects in the braking system components, contradicting the pilot's initial report of brake failure.
Findings
The sequence of events was driven by the combination of a short runway and challenging wind conditions. The decision to ground loop was made to prevent a runway excursion into hazardous terrain. The structural failure resulted directly from the forces generated during this maneuver rather than mechanical brake failure.
