‘Metal fatigue’ caused fatal Norway Airbus heli crash

A report by Norway’s Accident Investigation Board (AIBN) has discovered that metal fatigue was to blame for the crash of an Airbus Super Puma Helicopter in Norway two years ago that killed all 13 people onboard.

The crash two years ago occurred when the heli’s main rotor blades seperated from the helicopter itself, Reuters reported.

The helicopter was carrying passengers from an offshore oil platform in Norway.

The flight was being operated by CHC Helicopter, based in Canada, the report also stated.

“The accident was a result of a fatigue fracture in a second stage planet gear in the epicyclic module of the main rotor gearbox,” the investigators said.

The investigators also recommended that Airbus look at the design of the gearbox and potentially make changes.
