Read the full NTSB narrative

The airline transport pilot of the tailwheel-equipped airplane reported that the previous landing, which was flown by the pilot-rated passenger, was uneventful. The pilot then conducted the second landing, during which he reported that the right brake was not operating correctly, which resulted in asymmetrical braking. The airplane ground looped and sustained substantial damage. Postaccident testing of the brake system revealed that the right brake had a small leak from both o-rings only while pressurized. Both o-rings on both calipers were replaced, the brake system was pressurized, and no further leaks were found.
