'Technical' Errors Caused Fatal Norway Helicopter Crash

The helicopter crash that killed 11 oil workers and two crew on Friday was due to a technical error, the country's Accident Investigation Board said on Tuesday.

"We are as certain as we can be that a technical error caused the accident. We don't think it was due to human misinterpretations," the director of the board's aviation department, Kaare Halvorsen, told reporters.

An Airbus H225 Super Puma helicopter ferrying passengers from a Norwegian oil platform crashed in the North Sea on Friday, killing all 13 people on board.
