2002 Bristow Helicopters Sikorsky S-76A crash

G-BJVX, a Norwich-based commercial Sikorsky S-76A helicopter operated by Bristow Helicopters, crashed in the evening of 16 July 2002 in the southern North Sea while it was making a ten-minute flight between the gas production platform Clipper and the drilling rig Global Santa Fe Monarch, after which it was to return to Norwich Airport.

The rig Standby Vessel, Putford Achilles, which was about 1.5 mi (2.4 km) from the location, immediately launched its two fast rescue craft, which recovered four bodies and some floating debris.

Great Yarmouth Coastguard launched rescue helicopters and other vessels arrived on the scene that night, but no survivors or further bodies were recovered from the surface of the sea.

The wreckage, which included the helicopter's flight data recorder, was brought ashore at Great Yarmouth on 21 July, and transferred to an Air Accidents Investigation Branch facility near Aldershot, Hampshire, where it was examined by investigators from the AAIB, the US National Transportation Safety Board and Federal Aviation Administration, the aircraft manufacturer, and the operator.

The non-handling pilot carried out a "rotor track and balance" procedure; the increase in vibration did not cause the crew any immediate concern and the procedure was carried out to enable the Integrated Vehicle Health and Usage Monitoring System (IVHUMS) to log rotor track and balance data for later analysis.
