A total of 33 people have died in three fatal accidents involving the helicopters since 2009.
They were grounded in the wake of a crash in Norway last year but were later cleared to fly.

MSPs debated the issue at Holyrood on Tuesday while Unite demonstrated outside.

Helicopter operator CHC has already ended its use of Super Pumas, citing a "lack of commercial demand" from customers.
