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

During the taxi at the departure airport the pilot reported that the airplane required a significant amount of left rudder to remain on the centerline of the taxiway. The pilot did not believe the issue to be anything material and elected to continue the flight. After performing maneuvers, he made a normal approach to landing. Upon touchdown the airplane veered violently to the right, departed the runway, and struck a sign. The pilot reported that the lower portion of the right main landing gear had separated from the airplane during the accident sequence. Examination of the separated portion of the landing gear revealed no mechanical anomalies. The upper portion of the landing gear was forwarded to the Safety Board Materials Laboratory and found to have failed due to overstress cracking. The 1972-model airplane had 6,645 total hours of flight time at the time of the accident, and had received a 100-hour inspection 62-flight hours prior. The airplane had been used primarily for flight training since 1997.

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

The pilot's improper decision to continue the flight with known deficiencies in equipment. Also causal was the failure of the right main landing gear due to overstress cracking.
