What happened
On 19 August 2000, a WEEDHOPPER C, registered as ZS-VRW, was involved in an accident during a local flight near Philadelphia, South Africa. The aircraft was departing from a private airstrip in the Koeberg area for a short-duration flight within the same vicinity. During the takeoff phase, the aircraft suddenly became uncontrollable, forcing the pilot to perform an emergency landing on the N7 National Road, which connects Cape Town to Windhoek.
While there were zero fatalities, the pilot sustained minor injuries during the impact. The aircraft itself suffered substantial damage.
The investigation
Investigators from the SACAA AIID examined the wreckage and the maintenance history of the aircraft. The meteorological conditions at the time of the incident were reported as fine, with no adverse weather contributing to the event. Records indicated that the aircraft had been subject to correct maintenance procedures prior to the flight. The pilot held a valid private license and was appropriately endorsed to operate this specific aircraft type.
Findings
Technical analysis revealed that the loss of control was directly triggered by a mechanical failure within the flight control system. Specifically, a bolt detached from the control rod during the takeoff roll. This failure occurred because the necessary retaining nut had been omitted from the assembly, allowing the bolt to fall out and rendering the aircraft impossible to steer.
