Aircraft Accident/Incident Report
Burlington, Vermont 05403
Tuesady, October 2, 2012 9:00 EDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that he landed the multiengine airplane without incident; however, while taxiing after landing, the left main landing gear collapsed, which resulted in substantial damage to the left wing and left horizontal stabilizer. Subsequent examination of the airplane revealed that the left main landing gear bellcrank pin had separated from its bushing. The pin was not located; however, metallurgical examination of the left main landing gear bellcrank and retraction link revealed significant deformation and fracturing of the bellcrank bushing, which was consistent with a very large force applied along the axis of the link. The deformations on the link suggested that the pin fractured inside the hole and exited the bore as two separate pieces. Although an overstress failure seems probable, other failure modes, such as a significant fatigue crack cannot be ruled out because the fractured pin fragments were not located. The airplane was manufactured about 38 years before the accident. It had been operated for about 3,675 total hours, about 25 hours of which occurred since its most recent annual inspection, which was performed about 2 months earlier.
NTSB Probable Cause Narrative
The collapse of the left main landing gear due to a failure of the left main gear bellcrank pin for reasons that could not be determined because the pieces of the fractured bellcrank pin were not located.
