What happened
Following a normal landing, the pilot of the aircraft reported seeing three green lights on the landing gear indication system. The aircraft taxied for approximately 2,000 feet before the pilot initiated a right turn onto a taxiway. During this turn, the left main landing gear collapsed. An inspection of the accident site determined that the distance from where the propeller first struck the runway to the point where the aircraft came to rest was approximately 120 feet.
The investigation
An examination of the landing gear assembly identified specific mechanical failures. The only visible damage found on the left main landing gear system consisted of a sheared AN25-38A bolt, which connected the rod end of the bellcrank to the lower side brace, and a sheared NAS464P4-26 bolt, which attaches the upper portion of the bellcrank to the upper portion of the upper barrel. While the right main landing gear was found to be operational, the left main landing gear could not be operationally checked during the inspection.
