Port Alsworth, AK, USA

Aircraft #1

Analysis

The pilot reported that, during the landing roll while applying the brakes, the right brake “went flat.” The airplane veered to the left, impacted a stump, and nosed over, resulting in substantial damage to the fuselage and left wing. A postaccident examination revealed no mechanical anomalies with the brake system that would have precluded normal operation. Based on the available information, the reason for the loss of control during landing could not be determined.
