Analysis

The pilot reported that the airplane landed in a three-point configuration. Soon after touchdown the airplane veered right, and the left wing pitched up. The pilot depressed the left rudder pedal and reduced power. However, the airplane continued to veer right, departed the runway and impacted a chain link fence, which resulted in substantial damage to the right-wing strut. The pilot reported observing skid marks and a long trench consistent with the right main landing gear position in the accident path. The right main landing gear was found partially separated at the accident site. Postaccident examination of the right main landing gear by the accident pilot and his mechanic revealed that the oleo strut fractured and separated due to a failed weld on the upper attachment end, which resulted in a partial separation of the right main landing gear after landing.
