§ Mr. Menzies Campbell
To ask the Secretary of State for Defence what is the percentage serviceability target in 1999 for equipment being required to be available within 12 hours for(a) RAF aircraft, (b) army tanks and (c) other battle vehicles. 
§ Mr. Spellar
The Army do not set serviceability targets for equipment being required to be available within 12 hours. The percentage serviceability target in 1999 for90W equipment being required to be available within 24 hours is 90 per cent. for main battle tanks and an average of 80 per cent. across the range of other armoured vehicles.
The information requested on RAF aircraft is not held centrally but is being collated. I will write to the right hon. and learned Member when it is available and a copy of my letter will be placed in the Library of the House.
