§ Mr. MURCHISONasked the Secretary of State for War whether he can state the 1276W average life in flying hours under peace conditions of two-engined aeroplanes capable of carrying twenty to thirty passengers and single-engined aeroplanes carrying up to four passengers?
Captain GUESTThe period that has elapsed since civil flying under peace conditions commenced has been insufficient to allow such reliable data to be obtained as would enable a useful answer to be given to this question. The necessary data are being collected. It may, however, be observed in this connection that if the proper replacements, both of engine and aeroplane parts, are made during the periodical overhauls, there is no reason why any aeroplane should ever wear out, as after 200 hours flying there will probably be very little of the original machine left.
