Narrative:
The accident occurred whilst the helicopter was manoeuvring to land on the Shell Brent Spar, a permanently moored semi-submersible offshore storage and tanker loading unit. After the helicopter had approached to a hovering position adjacent to the helideck, several witnesses realised that it was positioned dangerously close to a part of the installation’s crane structure. The tail rotor blade tips contacted a handrail surrounding the anemometer mast which was attached
to the crane ‘A’ frame after which the helicopter crashed onto the helideck and almost immediately fell over the side of the deck and into the sea. Seven survivors were rescued from the sea having made their escape from the sinking helicopter.

Six occupants including the crew died. The AAIB report suggests impact injuries (a number of the non-crashworthy seats collapsed) as a probable cause for 4 passengers being unable to escape. Pax lifejackets were worn in a pouch around the waist.

Ten safety recommendations were raised. The aircraft had originated from Sumburgh, Shetland (LSI/EGPB).
