Event Description
During the landing rollout, the airplane experienced a sharp left deviation and a nose-down pitch, causing the right wing to strike the runway.
Post-Accident Inspection
After the event, an examination of the airframe was conducted. Investigators found a broken component in the nose gear steering system: the right side steering link rod.
Failure Analysis
The right side steering link rod had failed in fatigue. This fatigue failure resulted in the rod separating from the steering assembly. Following the separation, the left side rod end failed due to overload. With both rod ends compromised, all steering control was lost.
Conclusion
The loss of steering control during the landing rollout led to the aircraft's deviation and wing strike. The investigation determined that the initiating failure was a fatigue fracture of the right side steering link rod.
