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.
