HC Deb 28 October 1986 vol 103 c111W
Mr. Knox

asked the Secretary of State for Transport what is his policy towards the use of marginally unserviceable engines with regard to extended twin-engined aircraft operations.

Mr. Michael Spicer

The Civil Aviation Authority is statutorily responsible for aviation safety. It has informed me that the use of marginally unserviceable engines is not permitted for any purpose, least of all for extended range twin-engined operation.
