After landing on a gravel runway, the pilot applied brakes and found the right brake inoperative. The aircraft veered left, colliding with a berm. Examination revealed an improperly flared hydraulic line caused fluid loss.

Accident Sequence

Upon touchdown on a gravel runway, the pilot applied the brakes and discovered that the right brake was inoperative. The aircraft subsequently veered off the left side of the runway and collided with a berm. The pilot later stated that he had not checked the brakes prior to landing.

Post-Accident Examination

A post-accident examination of the aircraft revealed that most of the hydraulic brake fluid had drained out of the right brake system. The fluid loss was attributed to an improperly flared line at the right brake assembly.
