AAIB investigation to Agusta A109C, G-HBEK
Loss of control during approach to land, private landing site, Organford, Dorset, 15 July 2021.
Summary:
On approach to a private landing site, the helicopter experienced an uncontrolled yaw to the right. Despite applying full left pedal the pilot was unable to regain control of the aircraft and opted to cut the power, following which the aircraft hit the ground. In the absence of a mechanical defect, it is possible that the loss of control was due to a loss of tail rotor authority resulting from operating close to or at the controllability limits of the helicopter, or that the helicopter was overpitched, or a combination of both. The helicopter was damaged beyond economic repair and the pilot sustained minor injuries.
