Helicopter had returned to base twice before crash

A helicopter that crashed in Norway killing 13 people had to return to base twice in the days before the tragedy after a warning light was triggered.

Helicopter operator CHC confirmed that the Super Puma had to turn back to Flesland Airport in Bergen last Tuesday when the pilot spotted the indication light.

After a part was replaced, a test flight the following day was also aborted and another component changed when the light reappeared.
