During landing rollout, the left main landing gear collapsed and separated from the aircraft. The airplane ground looped and departed the runway to the left, turning 180 degrees and coming to rest on its left side. Postaccident examination of the aircraft revealed that the left main landing gear u-bolt failed. The bolt fractured through the bend between the horizontal and vertical leg of the bolt. The fractured surface revealed ratchet marks and crack arrest positions typical of fatigue cracking, while the fractured features on the remaining surface were typical of an overstress failure. The fractured surface of the bolt at the failure initiation area was damaged following the separation and the reason for the fatigue initiation was could not be determined.
Probable Cause: A failure of the left main landing gear attachment (u-bolt) due to fatigue.
