The UK's Air Accidents Investigation Branch is sending a team to Norway because it has investigated a number of crashes involving helicopters operating to and from offshore oil and gas fields in recent years.
In 2012, EC225 Super Puma helicopters crashed in two incidents in Scotland, one off Aberdeen and another off Shetland. Both crashes were blamed on gearbox problems.
In both cases, all passengers and crew were rescued, though in 2013 a Eurocopter AS332 also crashed in Shetland with the loss of four lives. EC225s in the UK were grounded following the crashes but given the go-ahead to resume flying in 2013.
