A review into offshore helicopter operations in the North Sea will compare UK fleets with those in Norway.
The CAA said its review will be undertaken with the Norwegian CAA and the European Aviation Safety Agency and will pay particular attention to:
- Operators' decision making and internal management
- The protection of passengers and crew
- Pilot training and performance
- Helicopter airworthiness.
The review follows five accidents in the last four years, the last of which in August this year claimed four lives.
