Narrative:
The pilot stated that the touchdown and initial landing rollout were normal. As the aircraft slowed to 20 mph the aircraft started an arc to the right. The pilot stated that full left rudder and brake 'made the arc tighten to the right...(and)...I released the left brake and applied a little right brake.' The arc began to lessen, but not enough to prevent the aircraft from leaving the runway and heading for a drainage culvert. The pilot was concerned about the aircraft striking the culvert and nosing over onto its back so he intentionally 'stepped hard on the right rudder and brake to purposely ground loop.' During the ground loop, the aircraft wing struck a concrete barrier above the drainage culvert. The aircraft was examined by an FAA airworthiness inspector who reported that he did not observe any damage or defect of the landing gear or brakes not related to the impact sequence.

Probable Cause: The pilot's failure to maintain directional control of the aircraft during the landing rollout.
