Fly-by-hour agreement
With conventional fly-by-hour services, customers pay a fixed price from day one for every hour flown, and in return they are offered a comprehensive range of services–engine removal, repair and installation, and the supply of a replacement engine to keep the aircraft flying. These flat rates are particularly popular with owners of newly developed aircraft and engines because they cover unscheduled shop visits and the replacement of parts, known as early removals. Fly-by-hour packages are offered by OEMs—Rolls-Royce, GE Aviation or Pratt & Whitney—who have the work carried out in their network shops. Independent MRO providers like MTU Maintenance also offer fly-by-hour agreements.
