Analysis

The airplane veered off of the runway during landing. The pilot reported that during the landing, he heard a loud noise and then the airplane veered off of the runway. Upon inspection, the landing gear scissor assembly was found broken loose from the upper mounting collar on the landing gear strut and the lower strut was rotated about 90 degrees. A request was made that the broken parts be sent to the National Transportation Safety Board investigator for further examination. The parts were not received. No other anomalies were found with the airplane or its systems that could be associated with a pre-impact condition.
