Turbine Helicopters Accidents list

David Learmount/LONDON

See also Loss of Control

Individual turbine-helicopter accident details have been supplied by Airclaims* from its World Airline Accident Summary (WAAS), which it compiles and publishes on behalf of the UK Civil Aviation Authority. The WAAS also provides analysis by category under aircraft type, event, location and operator, and the publication benefits from Airclaims' exclusive information-exchange agreement with the CIS Interstate Aviation Committee (MAK)Commission for Flight Safety.

Although we make every effort to ensure the listing of complete and accurate data, users should not employ the information for legal purposes or precise statistical analysis. The availability of data is prejudiced by the fact that some remote-area operators involved in high-risk helicopter work, particularly with light or low value helicopters, do not insure their airframes, so accidents are not reported. This list, therefore, should be considered an indicator of accident types and trends, not a complete catalogue.

The criterion for listing an accident/incident is that it involves fatality or serious injury, and/or significant damage to the aircraft.

The pilot made a precautionary landing, saying the aircraft 'wanted to spin'. Finding no problems, he took off and climbed to 6,000ft, but the control difficulty returned so he started an autorotative descent. On applying collective to flare, however, the aircraft rolled and the main rotor hit the ground. The same airframe had been reported 'destroyed' in an accident in Florida, 26 June, 1992. The pilot reported that he bought the aircraft in December 1996 in Florida.
