NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

While exiting the runway after landing, the right main landing gear collapsed, and the right wing struck the runway. The pilot reported that this was the first flight after an annual inspection in which the landing gear had been rigged. In addition, he had the failed components sent to a metallurgical laboratory. The owner submitted these findings to the Safety Board. The inspection report indicated that the right main landing gear had been rigged so that the gear tension terminated prematurely. This prevented the downlock link from reaching its full over center, locked position. This caused the side loads on the landing gear to be transmitted through other landing gear linkage components, instead of through the downlock link. The other components were not designed to carry those loads, and consequently failed in overload, resulting in the collapse of the landing gear while taxiing off the runway.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The landing gear collapsed during taxi as a result of incorrect rigging of the landing gear by other maintenance personnel that prevented the landing gear downlock from functioning as designed.
