The Royal Air Force has operated fleets of a number of different aircraft types over a long period of time. Maintenance arrangements have evolved as aircraft technology has become increasingly more complex and lessons are learned from previous contracts and processes. Current arrangements vary by fleet but range from in-house maintenance carried out by qualified service personnel to availability contracts, specifying airframe numbers and flying hours but inherently including maintenance.
Through this evolution, efficiencies have been made through the Department's close partnership with industry and rationalisation of infrastructure and processes. The Royal Air Force and industry are committed to a strategy of continuous improvement of both the efficiency and the effectiveness of aircraft maintenance.
