What happened
On January 3, 2001, a Cessna 182 RG, registration ZS-LBG, was performing a takeoff from a private grass airstrip located in Hluhluwe. During the initial stages of the takeoff run, specifically after the aircraft had traveled approximately 100 meters along the ground, the nose wheel undercarriage suddenly collapsed. The impact resulted in damage to the propeller and the lower engine cowling. The pilot, who was the sole occupant of the aircraft, was uninjured during the incident.
The investigation
Following the occurrence, the aircraft was recovered by an Approved Maintenance Organization (AMO) and transported to their facility for repairs. Investigators examined the mechanical integrity of the landing gear assembly to identify any underlying failures. The inspection focused on the electro-hydraulic systems and the physical condition of the locking mechanisms. While the investigation noted that the down lock hooks exhibited slight wear, this was not identified as a primary cause for the structural failure. Furthermore, the hydraulic and electrical systems responsible for gear operation were found to be fully serviceable.
Findings
- The investigation could not identify a specific mechanical defect or component failure responsible for the collapse.
- The rough condition of the grass airstrip was noted as a significant factor, as such terrain can place extreme stress on the undercarriage of light retractable-gear aircraft.
- The wear observed on the down lock hooks was deemed insufficient to trigger the collapse.
