HC Deb 08 July 1965 vol 715 cc315-6W
Sir R. Russell

asked the Secretary of State for Defence how many crashes of helicopters through engine failure on non-operational flights have occurred in any recent convenient period of twelve months; and how these accidents compare with the total number and mileage of flights.

Mr. Millan

During the twelve-month period ending 30th June, 1965, three Service helicopters crashed as the result of an engine power failure while undertaking flights of a non-operational nature. There were no fatalities. No records of mileage are kept for this purpose, but in the same period Service helicopters carried out 170,000 non-operational flights.
