What happened
On 18 January 2008, a student pilot operating a Robinson R22, registration ZS-HTP, departed Virginia Aerodrome for a solo training session. The flight's objective was to practice "quick stop" maneuvers within the general flying area.
After successfully completing the maneuvers, the pilot entered a transition phase. During this period, the pilot identified telephone wires in close proximity to the aircraft. In an attempt to maneuver away from the hazard by turning left, the helicopter's tail rotor struck the wires, causing the aircraft to crash. The pilot sustained no injuries, though the aircraft suffered significant damage to the cabin, skids, tail boom, tail rotor gearbox, and drive shaft. The impact also caused damage to the telephone wires.
The investigation
An investigation by the SACAA AIID established that the weather conditions at the time of the accident were favorable, with clear visibility and light winds, ruling out meteorological factors as a cause. The investigation confirmed that the aircraft was properly maintained, with no mechanical anomalies or defects reported prior to the impact. The flight was also conducted under the authority of a valid aviation training organization.
Findings
- The accident was caused by the pilot's failure to maintain a proper lookout for obstacles.
- The tail rotor made direct contact with telephone wires during an avoidance maneuver.
- The student pilot held a valid license and appropriate ratings.
- The aircraft was in a serviceable condition and compliant with regulatory maintenance requirements.
