Investigator assessment
Analysis narrative
After touchdown on the gravel runway, the pilot applied brakes and found the right brake inoperative. The airplane veered off the left side of the runway and collided with a berm. The pilot said he did not check the brakes prior to landing. Post accident examination found that most of the hydraulic brake fluid had drained out of the right brake system from an improperly flared line at the right brake assembly.
