British Airways has for some time been operating TriStar-1 aircraft over a wide range of sector lengths and is currently planning the introduction of the -500 longer range variant in 1979. Development of the engineering aid maintenance organization to support these wide-body aircraft has progressed in parallel with the increase in the airlines' fleet, and has had to take account of the Reliability and Maintainability concepts formulated in the 1960's. The most stringent operational constraints influencing Reliability and Maintainability affecting the TriStar fleet (as in other types), are: fast turnarounds; high concentration of services over a relatively short period; and a wide range of maintenance facilities at stations. Considerable effort has been expended on preparing for overhaul and maintenance of the RB 211 engines and associated systems, and a large test bed with a 75,000 lb thrust capability was put into operation in 1975. Of great value is the ability to investigate all rotating blades and the combustion chamber of the engine with a borescope which has revealed problems which would otherwise have involved unscheduled engine removals. The value of these inspections may be appreciated by the fact that 62% of British Airways scheduled removals of RB 211 result from this borescope facility. Another process which has proved of great value is that involving magnetic particle detection which is available at several locations in the engine.
