Confidence Rating: Accident investigation report completed and information captured
Crashed into sea on night time approach approximately 300 metres southwest of the BP's ETAP offshore installation , 125 miles E of Aberdeen.

The crew’s perception of the position and orientation of the helicopter relative to the platform during the final approach was erroneous. Neither crew member was aware that the helicopter was descending towards the surface of the sea. The approach was conducted in reduced visibility. This degraded the visual cues provided by the platform lighting, adding to the strength of the visual illusions during the final approach. The two radio altimeter-based audio-voice height alert warnings did not activate.

The helicopter remained upright in Sea State 5, supported by its emergency flotation system which had inflated automatically. All those onboard were able to egress into liferafts and they were later rescued by air and maritime Search and Rescue (SAR) assets in just under 2 hours.

Wreckage at Cranfield University accident investigation lab.
