§ 44. Mr. BrightTo ask the Chancellor of the Duchy of Lancaster what proportion of the Boeing 747 series of aircraft is manufactured by the British aerospace industry.
183W
§ Mr. ForthA number of United Kingdom aerospace companies participate in the Boeing 747 programme but the United Kingdom share is largely dependent upon the choice of engine. If a Rolls-Royce engine is selected, as is increasingly the case, the United Kingdom share of the initial sale value of the aircraft is 25 per cent., rising to 30 per cent. of its lifetime value once engine spares have been provided.
