HC Deb 16 December 1955 vol 547 cc231-2W
Sir A. Bossom

asked the Minister of Transport and Civil Aviation to what extent all the combustible material used in passenger-carrying aircraft is required under his regulations to be fireproof, as is required for all material used in tall buildings over a certain height.

Mr. Boyd-Carpenter

Materials used in the construction of modern civil aircraft are required to conform to British Civil Airworthiness Requirements which specify that sources of fire (e.g. engine nacelles) shall be isolated from the main structure and the cabin by fire walls; that material used in the construction of fire walls and in the fire zones themselves shall be fire proof to the extent that it is resistant to the application of a hot flame for a prescribed period and that material used in other parts of the aircraft (e.g. cabin furnishings) shall be flame proof to the extent that it is not easily ignited and will not propagate combustion.

In addition, all such materials are required to conform to specifications approved by the Air Registration Board, resistance to fire being one of the properties specified.
