What happened
On 19 February 2011, a private flight operating under Visual Flight Rules (VFR) was en route from Rooikoppies private aerodrome to Ntokoza Lodge. The flight, involving a pilot and one passenger, proceeded normally following a standard pre-flight inspection and departure. After approximately 55 minutes of flight time, the pilot began a descent toward runway 16 at Ntokoza Lodge.
As the Aerotrike Cobra approached the runway surface at an altitude of roughly 4 to 6 feet, the aircraft's wings began to vibrate violently from side to side. The pilot reported a sudden, steep drop in altitude. The aircraft touched down left of the runway centerline, striking the ground with the right wheel first, followed by the left and nose wheels. During the subsequent rollout, the left wheel support tube failed, causing the aircraft to skid off the runway and strike a tree. There were no injuries to the occupants.
The investigation
SACAA AIID examined the wreckage and the circumstances surrounding the landing. The investigation confirmed that the pilot held a valid private pilot license and medical certificate, and the aircraft, registration ZU-CSS, possessed a valid authority to fly. Maintenance records indicated the aircraft had been serviced according to the approved schedule, with the most recent annual inspection completed shortly before the event.
Technical analysis of the engine and airframe revealed no mechanical malfunctions or defects that contributed to the incident. The investigation also noted that the aircraft was equipped with standard navigation instruments, all of which were functional, and the weather conditions at the time were clear with good visibility.
Findings
- The aircraft was properly maintained and the engine was operating normally prior to impact.
- The flight was conducted during daylight hours under VFR.
- The accident was the result of the pilot losing directional control during the landing phase.
