A team of air accident investigators from the UK are travelling to Norway following a helicopter crash in which 13 people died.

The Air Accidents Investigation Branch (AAIB) team will help Norwegian investigators examine the crash, which took place near the city of Bergen. A Scot is understood to be one of the victims.

Following the crash on Friday afternoon all UK Super Puma helicopters were grounded by the Civil Aviation Authority (CAA) subject to further investigations.

The helicopter was flying from the Gullfaks oil field to the Norwegian city.

On Saturday, Norwegian television reported that wreckage of the helicopter had been recovered from the water.

AAIB chief inspector Keith Conradi said: "We were sad to hear of the loss of a helicopter west of Bergen, Norway.

"The Air Accidents Investigation Branch has offered to assist the Accident Investigation Board Norway with their investigation and is deploying a team of inspectors."

The CAA said in a statement: "Following the accident the UK CAA has issued an instruction to stop any commercial passenger flights by UK operators flying the Airbus EC225LP helicopter. This mirrors action taken by the Norwegian CAA. The restriction does not apply to search and rescue flights.

"The accident involved a Norwegian helicopter and will therefore be investigated by the Norwegian authorities. We will offer any assistance that we can."

A Norwegian Civil Aviation Authority official confirmed to local media that the helicopter involved had maintenance servicing delayed twice in 2015.

Hege Aalstad, a senior legal adviser at the authority, said: "I can confirm that this specific helicopter had seen its maintenance delayed. It is correct that there was an application for a so-called travel-time extension.

"The first one was for a delay of 100 flying hours ... and the other was also for 100 flying hours."
