The certified flight instructor and student pilot had just performed a soft-field landing. During the subsequent rollout, they noted that the airplane was not taxiing as expected. As the airplane exited the runway, it dropped onto its left wing and spun to the left. Examination of the left main landing gear revealed that the upper torque-link attachment lugs had detached from the landing gear strut, causing separation of the wheel assembly and subsequent substantial damage to the left wing. Further metallurgical examination of the strut revealed evidence of preexisting fatigue cracks to the upper torque-link attachment lugs. The airplane manufacturer issued a Service Bulletin about 8 years prior to the accident requiring inspection of the lugs in the area of failure. No evidence was found suggesting that the Service Bulletin had been complied with.
Probable Cause: Fatigue cracking of the upper torque-link attach lugs on the left main landing gear strut, which resulted in separation of the left main landing gear during taxi.
