Analysis

During the landing roll, the right gear collapsed & the acft veered off the rwy. An exam revealed that the right wheel ass'y had separated from the gear leg. There was evidence that the 2 lower bolts had been stripped prior to the wheel failure, either by being overtorqued or by a series of hard landings. The prior owner had used the acft in a sport parachute operation.
