Crew

The commander of the flight was Cedric Roberts (44). He had been with Bristow Helicopters Ltd since 1974. He was a very experienced pilot with more than 9,600 hours of flying time under his belt. The first officer was Lionel Sole (39). Sole had been with Bristow Helicopters Ltd since 1990. He had more than 3,100 hours of flying time to his credit.[3]

Accident

En route, the helicopter ran into poor weather and was then struck by lightning. This caused severe damage to the tail rotor. Though the helicopter managed to limp for a few more minutes, the tail rotor eventually failed completely and the pilot was forced to perform an emergency autorotation onto the rough seas. Emergency floaters on the helicopter allowed the passengers and crew to be evacuated onto a life raft. Despite the high waves and bad weather, all the people on board the flight were rescued by the ship Grampian Freedom.

The lightning strike was an isolated one in the storm, and may have been induced by the helicopter flying through the cloud. The accident investigation also revealed potential troubles with the carbon fibre composite material with brass strip design of the rotors which made the rotorblades prone to explosion and damage from lightning strikes.

In popular culture

The events of Flight 56C were featured in "Helicopter Down", a Season 3 (2005) episode of the Canadian TV series Mayday[4] (called Air Emergency and Air Disasters in the U.S. and Air Crash Investigation in the UK and elsewhere around the world).
