What happened
The incident occurred during the initial phase of flight on an unimproved grass strip. According to the pilot's account, the aircraft was accelerating down the runway when it began to veer unexpectedly at approximately 50 knots. Despite having no prior indication of mechanical issues or irregularities with the airframe, the pilot was unable to maintain directional control. The aircraft departed the paved surface, struck a fence located along the perimeter of the strip, and subsequently rolled over onto its back.
The investigation
Following the accident, investigators conducted a physical examination of the wreckage to determine the root cause of the loss of control. The inspection focused heavily on the landing gear systems, specifically the nose wheel assembly. Forensic analysis revealed that the right-hand steering linkage had suffered a catastrophic failure. This mechanical break prevented the pilot from effectively steering the aircraft during the critical takeoff roll.
Findings
The investigation concluded that the primary factor leading to the accident was the premature failure of the nose wheel steering linkage. The pilot reported no awareness of any pre-existing defects, suggesting the failure occurred suddenly during operation. The loss of directional control at high speed resulted in the aircraft leaving the runway environment and sustaining significant damage from the impact with the fence.
