Analysis

The pilot landed long at a private grass airstrip and deliberately ground looped the aircraft to avoid overrunning the airstrip into a three foot ditch. The nose gear collapsed during the ground loop and the wings and main gears were damaged when the aircraft slid sideways across a ditch at the end of the runway. The pilot reported little braking action as the airstrip was wet from recent rains.
