Destination airport:Brae Alpha platform
Investigating agency: AAIB
Struck by lightning while descending to the Brae A platform in the North Sea. Part of a tail rotor blade was lost. The resulting heavy vibrations resulted in a fatigue failure of the Tail Gear Box mounting. This resulted in loss of tail rotor drive. The TGB however remained held in place by its hydraulic pipes, avoiding a shift in CG and a catastrophic pitch down.

The helicopter successfully ditched in the rough sea (~Sea State 5), all POB (2 crew and 16 passengers) evacuated and were rescued. It sank some time after the after evacuation.
