1999 Cessna T210M Accident at Wonderboom Airport (ZS-LWA)

Overview and Flight Details On 25 July 1999, a Cessna T210M with registration ZS-LWA was involved in an accident at Wonderboom Airport. The aircraft was operating a ferry flight from Laingsburg to Wonderboom Airport. The pilot-in-command held a commercial licence and had 1,030 total flying hours, including 83.75 hours on type. The accident occurred at 1420Z. ## Accident Sequence After touchdown, the pilot applied brakes, and the right-hand main landing gear collapsed. The aircraft then veered off the runway to the right. The pilot was the only person on board, and no injuries were reported. The aircraft sustained substantial damage. ## Technical Findings All flight and engine controls were serviceable before the accident. The down-lock micro-switch on the right-hand main landing gear was found stuck in the closed position, which provided a false indication in the cockpit that the landing gear was down and locked. As a result, the right-hand landing gear was not fully deployed during landing. When the aircraft landed, a backpressure was created in the system, causing the left-hand main landing gear actuator to rupture.
