What happened
On 8 December 2021, a pilot was conducting a scheduled proficiency flight for crop-spraying operations at Broodkraal Farm, located near Piketberg in the Western Cape. The flight, performed under visual flight rules, was intended to be a single-circuit assessment to evaluate the pilot's maneuvers, spraying height, and landing techniques. An assessor accompanied the pilot during this session.
During the takeoff roll from the private airstrip, the RAF 2000 GTX gyrocopter, registration ZU-DUY, experienced an unusual sequence of events. While the initial startup and pre-rotor procedures were normal, the takeoff roll appeared longer than usual. Upon the application of full power, the aircraft rolled to the left and abruptly ascended to a height of approximately 10 to 15 meters with a high nose-up attitude. This was immediately followed by a sudden nose-dive. The aircraft struck the ground on its right side while still at full power, resulting in a post-impact fire. The pilot sustained 1 fatality due to the impact, while the assessor suffered burns to the hands while attempting to rescue the pilot from the burning wreckage.
The investigation
SACAA AIID examined the circumstances surrounding the accident, noting that the pilot was properly qualified with a valid medical certificate and an agricultural rating. At the time of the accident, the aircraft was within its maximum takeoff weight limits, weighing 624.8kg against a limit of 680kg. The investigation also confirmed that the operator held a valid Air Operating Certificate and that the aircraft had undergone its annual inspection recently.
Findings
- The primary cause of the accident was a loss of control during the takeoff roll, which occurred because the pilot attempted to rotate the aircraft before reaching the required rotation speed of 55 mph.
- Environmental conditions were favorable, with a light wind of 8km/h and clear visibility.
- The aircraft was destroyed in the crash.
Safety action
Following the incident, a safety message was issued reminding pilots of the necessity to strictly adhere to manufacturer-defined operational limits to prevent injury and property damage.
