The UK Air Accidents Investigation Branch (AAIB) has issued a special bulletin concerning the April 1 crash of a Eurocopter AS 332L2 Super Puma in the sea near Peterhead, Scotland. The investigation has determined that a failure within the epicyclic reduction gearbox module of the main rotor gearbox caused the rupture of the gearbox case, which allowed the main rotor head to separate from the helicopter.
