What happened
On 21 September 2003, a MAGNI-GYRO M16 gyroplane, registration ZU-CZI, was performing a takeoff roll at a private aerodrome in the Maretsane district. The flight was intended to proceed from Mafikeng Aerodrome to a private landing site nearby. During the initial takeoff phase, while traveling in a westerly direction, the aircraft was struck by a sudden, strong gust of wind originating from the northwest. This unexpected wind caused the pilot to lose directional control, leading the aircraft to veer sharply to the left. The gyroplane subsequently departed the runway, overturned, and eventually came to a stop against the aerodrome's perimeter fence.
The investigation
Investigators examined the wreckage and the environmental conditions present at the time of the incident. Meteorological data indicated fine weather with good visibility and a temperature of 32°C, though a northwesterly wind of 12 knots was noted. The investigation confirmed that the aircraft, which had only 85.9 total airframe hours, possessed a valid Authority To Fly. The physical damage to the aircraft was significant, including damage to the cockpit area, the propeller, and the right main landing gear. Additionally, the main rotor head and the main rotor blades sustained substantial damage during the overturn.
Findings
- The primary cause of the accident was the unanticipated strong gust of wind from the right side of the aircraft during the takeoff roll.
- This wind gust prevented the pilot from maintaining the necessary directional control on the runway.
- There were no injuries reported for the sole occupant of the aircraft.
