Narrative:
Destroyed 20/11/1984 when crashed into the North Sea, 50 miles East of the Humber at co-ordinates 53"51' N, 01'13'E on a night approach to the Cecile Provine Oil Rig. Helicopter came down 200 metres north of the Rig. According to the following extract from the official AAIB report into the accident:

"The helicopter departed from its base at North Denes near Great Yarmouth at 17:57 hours local time, to carry out various transport tasks on several rigs in the Southern North Sea. Its final task of the day was to collect 7 passengers from the Cecile Provine Oil Rig and transport them back to Great Yarmouth.

During the night approach to this rig, in reasonable weather conditions, the helicopter crashed into the sea 200 metres north of the rig. Witnesses on the Cecile Provine oil rig watched the helicopter sink, and although floating debris was seen coming to the surface, including a life raft, there was no sign of survivors.

A search and rescue operation was begun at once, in response to a distress call from the Cecile Provine Oil Rig. However by midnight, it became clear that there were no survivors to be found, and the operation was terminated. Most of the wreckage was recovered from the sea bed in two diving operations during the next few weeks".

The AAIB report concludes that control of the helicopter following a decay in rotor rpm whilst the engines were still delivering full power. There was insufficient evidence from the wreckage recovered to determine the cause of the rotor rpm decay."

Damage to airframe: As the AAIB report confirms, the aircraft was "destroyed" (although the wreckage was largely recovered). As a result, the registration G-BJJR was cancelled by the CAA as aircraft "destroyed" just over two years later, on 29/1/1987
