An emergency airworthiness directive for several Eurocopter types has been issued by the European Aviation Safety Agency after an AS332 Super Puma helicopter suffered brake failure when landing on the helideck of a North Sea offshore oil rig, and "started to roll toward the edge of deck", the agency reported.
There have now been three EASA emergency ADs in the last two months relating to Eurocopter helicopters, but they are unrelated to each other.
