Probable cause
The malfunction of the right brake for reasons that could not be determined because postaccident examination revealed no anomalies that would have precluded normal operation.
NTSB narrative
The pilot reported that he was landing the tailwheel-equipped airplane in variable wind conditions. During the landing roll, he applied both heel brakes. When the pilot released the brakes, the right brake did not release. The airplane veered right of the landing path on the dirt airstrip, and the left wing struck a power line pole. During postaccident examination, the brakes operated normally with no anomalies noted.
