Event Location
Probable Cause
The pilot's inability to maintain directional control during the landing roll as a result of a piece of concrete from the runway impacting the right main landing gear brake during the landing roll, resulting in a right brake failure and a ground loop.
Full Narrative
During a telephone interview, the pilot of a tailwheel equipped airplane reported that during the landing roll on a private agricultural airstrip, a piece of concrete from the runway chipped off and hit the right brake. The pilot further reported that he applied the brakes to stop on the runway and then ground looped to the left. During the ground loop, the fuselage sustained substantial damage.
The pilot reported there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
A postaccident mechanical inspection revealed that the hydraulic line on the right main landing gear was severed, which would have made the right brake inoperable.
