Factual narrative

The pilot of the tailwheel equipped airplane reported that during the landing rollout, after the tail came down, he felt and heard a “bang” as the airplane rolled over a concrete ring, embedded in the turf runway. The airplane continued down the runway and the right main landing gear tire dug into the ground, followed by the collapse of the right main landing gear. The fuselage sustained substantial damage. After exiting the airplane, the pilot noticed that the tailwheel steering link was broken. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.

Probable cause

The pilot’s loss of directional control during landing due to impact with a concrete ring embedded in the grass runway. The National Transportation Safety Board determined the probable cause of this accident.
