136-432: A division between the roles of carrying out repair and maintenance on the one hand, and certifying the vehicle or subsystem or component as flightworthy, on the other. ICAO requires that the certification privilege be a delegated function of the nation's responsible Secretary of State. The Secretary of State may authorize another organization to grant the certification privilege to staff on their behalf. In Europe, licensing

170-435: A fixed sum per flying hour. A complete engine and accessory replacement service was provided, allowing the operator to accurately forecast this cost, and relieving him from purchasing stocks of engines and accessories. In the 1980s, Rolls-Royce plc reinstated the program to provide the operator with a fixed engine maintenance cost over an extended period of time. Operators are assured of an accurate cost projection and avoid

204-543: A maintenance checks or blocks which are packages of maintenance tasks that have to be done on an aircraft after a certain amount of time or usage. Packages are constructed by dividing the maintenance tasks into convenient, bite-size chunks to minimize the time the aircraft is out of service, to keep the maintenance workload level, and to maximize the use of maintenance facilities. An engine failure can significantly impact operations and revenue. A programme of calculated pre-emptive engine changes, sometimes referred to as "power by

238-578: A maintenance organization to grant the certification privilege to staff on their behalf. The ICAO defines the licensed or rated role of aircraft maintenance by a technician, engineer or mechanic), allowing that each contracting state may use whichever of these terms it prefers. Although aircraft maintenance technicians, engineers and mechanics all perform essentially the same role, different countries may use these terms in different ways to define their individual levels of qualification and responsibilities. Most national and international licensing bodies make
