News, Accident | The helicopter crash: These are the latest details about the accident

--

This is revealed in a new update from the National Accident Investigation Board.

There were six people on board when the helicopter took off from Flesland to carry out SAR training on the evening of 28 February this year.

West of Sotra, a training buoy with a radio transmitter was released to be searched for. It was during the work on this buoy that the accident occurred, reports the Norwegian Accident Investigation Board.

– The accident happened when the crew was in the process of positioning the helicopter to take up the buoy. It was dark and with few external visual references, they write on their pages.

Few seconds

Analysis of data from the tachograph shows how the helicopter rose and descended just before it went wrong. At one point, the helicopter’s “nose” rose abnormally from the expected 10-12 degrees to close to 30 degrees.

– This happened within a few seconds. When the flight crew became aware of the abnormal position they tried to correct it, but the helicopter hit the sea and sank at a depth of 220 metres.

The Accident Investigation Board is now working to establish the reason why the helicopter’s nose continued to rise beyond the expected 10-12 degrees.

The helicopter was equipped with flotation elements, but these were not automatically released upon impact. When the main rotor blades hit the sea, the power supply required for an automatic release of the floating elements ceased, according to the Accident Investigation Board.

Since then, an amendment to the regulations which, among other things, includes floating elements has been published.

– The S-92 helicopter type will gradually undergo adaptations to satisfy the new regulations. Requirements for implementation are set for August 2025.

One died

Nurse Reidun Hestetun (61) died in the accident that evening. One of the others on board was critically injured, and all were sent to hospital after the crash.

Two different rescue helicopters retrieved the six from the accident helicopter out of the sea and transported them to Haukeland. Hestetun was lifeless in the sea, and without an activated life jacket.

Lifejackets used in helicopters must be released manually, according to the commission. The rescuers prioritized picking up the five survivors first.

– The situation for one of the rescued became critical and the rescue helicopter was consequently unable to take the lifeless person, they write.

The woman was picked up by the second rescue helicopter which arrived somewhat later.
