HC Deb 28 November 1983 vol 49 cc380-1W
Mr. Robert Atkins

asked the Secretary of State for Defence if he will make a statement on the use of Lynx helicopters by the armed forces following the Civil Aviation Authority action on grounding.

Mr. Stanley

Following tests on the tail rotor of the Lynx aircraft which revealed a source of unexpectedly high stress on the control mechanism, the Civil Aviation Authority and Westlands Limited recommended on 18 November that flying by Westland 30 and Lynx aircraft, which have a common power plant and controls, should be restricted to operationally necessary flights only, with hourly inspections of the tail rotor.

As a result of further work Westlands was able to issue guidance on 24 November following which it is hoped to be able to resume shortly non-operational flying, subject to hourly inspections, and operational flying with some limitations, but less frequent inspections. We are awaiting further advice from Westlands, which is urgently seeking a permanent solution to this problem.
