Some of the roll and pitch angles you claim to use are unbelievable. It is scary to see that some pilots have so little respect for operating limitations.

The copilot of a CHC Scotia Super Puma sustained a serious leg injury, and the aircraft was badly damaged, when it rolled over on the helideck of the drillship West Navion. The vessel was operating for BP and located some 6Onm west of Shetland when the incident occurred on 10 November. Tasked with picking up 12 passengers, these waiting to board for transportation back to Aberdeen, the aircraft had been refuelled rotors-running with the copilot supervising and the captain at the controls when the accident occurred. Sources advise that at the time there were some 35 knots of wind and a moderate sea state, plus a reported heave of some 10-12 feet for the bow-located helideck. This was within CAA- and client-approved criteria for operation to this type of vessel, but since the incident both CHC Scotia and Bristow have placed interim restrictions on movement levels. For drillships of this type, the previous pitch and roll of 2.5 degrees has been reduced to 1 degree and heave is down from four metres to two metres, with the UK Air Accidents Investigation Branch, British health & safety agencies, BP and CHC Scotia carrying out investigations. The aircraft was taken to Norway and lifted ashore for detailed investigation at sister company CHC Helikopter Service's Stavanger/Sola engineering facility.
