The acfts left main gear collapsed during the landing roll. Investigation revealed that the bolt on the top portion of the LH bellcrank assembly was sheared off. One of the tangs at the bottom of the bellcrank was also broken. When examined under a 10 power microscope the fractured revealed instantaneous overload characteristics.
