This statement provides an update on the AAIB investigation into an accident involving an Enstrom 280FX helicopter, G?OJBB, near Dolgellau, Gwynedd, on 25 August 2021.
The helicopter suffered a loss of thrust from the tail rotor while hovering close to the ground near a mountain top, resulting in a loss of control and hard landing.
The AAIB investigation has focused on the tail rotor gearbox which shows internal damage that is consistent with a lack of lubrication.
