What happened
On 20 October 2001, a Sycomore MK IV gyrocopter, registration ZU-CLF, was involved in an accident during a takeoff attempt at Microland Runway 03. The pilot intended to conduct a local flight within the general flying area. During the initial takeoff roll, the aircraft's forward speed increased rapidly; however, the rotor disk was tilted too far forward, preventing the aircraft from lifting off the ground.
In an attempt to achieve flight, the pilot applied significant rearward cyclic input. While the aircraft did become airborne, this excessive input caused the pilot to lose directional control. The gyrocopter rolled to the right and struck the runway surface. The impact caused substantial damage to the aircraft, though there were no injuries to the two occupants on board.
The investigation
SACAA AIID examined the circumstances surrounding the takeoff roll and the pilot's subsequent maneuvers. The investigation confirmed that the pilot held a valid private pilot license with the appropriate type endorsement. The aircraft's authority to fly was also valid at the time of the occurrence. Meteorological conditions at the time were reported as CAVOK with a temperature of 15°C and winds from 360° at 10 knots.
Findings
- The primary cause of the accident was excessive cyclic input following an improper takeoff configuration.
- The rotor disk was tilted too far forward during the initial takeoff roll, which prevented immediate lift.
- The pilot's reaction to the lack of lift—pulling the cyclic back too far—led to the loss of directional control and the subsequent right-hand roll into the runway.
