What happened
On 6 December 2003, a Windlass Aquilla microlight, registration ZU-CHR, was conducting a training flight near Ixopo. The flight originated from Amble Inn, a farm located near Port Shepstone, with the intention of returning to the same location. The aircraft was carrying two occupants: the pilot and a student.
During a downhill takeoff into a headwind, the aircraft became airborne but was unable to establish a positive rate of climb. To avoid encountering power lines, the pilot executed a left turn, flying parallel to the lines along the valley. As the aircraft then drifted toward a blue-gum plantation, the pilot attempted an evasive maneuver by turning to the right. During this turn, the aircraft struck the power lines.
The investigation
Investigators examined the circumstances surrounding the flight and the mechanical state of the aircraft. The pilot held a valid microlight license and medical certificate, with the appropriate type rating for the Windlass Aquilla. The aircraft, which had a total of 891 airframe hours, was properly maintained, featuring an engine installed in March 2003 and having completed its last annual inspection recently.
The training school involved held valid CAA accreditation at the time of the occurrence. Both occupants of the aircraft survived the impact with minor injuries, though the aircraft sustained substantial damage.
Findings
- The pilot reported that the engine was producing full power during the incident.
- The aircraft's inability to climb was attributed to wind effects over the terrain, specifically wind blowing over the mountain and down the valley, which likely created a downdraught that prevented the aircraft from gaining altitude.
