Bell 206B Jet Ranger II, G-WLLY
The pilot of the helicopter and an observer were carrying out a pipeline inspection flight between Cumbernauld Airport and Aberdeen. Approximately 45 minutes after takeoff, the helicopter descended to low level where debris was seen to fall from its aft section. Control of the helicopter was lost and it struck the ground, fatally injuring both occupants. The investigation found that the vertical stabiliser had detached from the tail boom and struck the tail rotor. This subsequently caused the tail rotor and associated gearbox to become detached from the tail boom, resulting in the helicopter’s centre of gravity moving outside controllable limits.
