The Rolls-Royce RB211 is a large turbo-fan gas turbine engine which powers many of the most advanced airliners in service today. Rapid and effective maintainability is vital to the running of the airline transportation industry, and one of the complex items which is an important part of this industry is the aeroplane powerplant. Maintainability is fundamentally the process of keeping devices in the condition to which they were designed, and in the case of civil aero engines, one of the activities necessary for continued compliance with their Certificate of Airworthiness for public transportation. This paper looks at the evolutionary process which has influenced the maintainability of the RB211 engine series, where history has shown its original revolutionary concepts to be excellent, and experience has dictated needs, and found ways and means of further enhancement. Engine size increases and the advent of the electronic revolution have also had their influence, and are touched on in the paper. It therefore provides a snapshot of the principal maintainability featuers created by killed designers, and improved as a result of feedback from use by customers.
