Each Contracting State is expected to use in its own regulations the one it prefers.' Thus, aircraft maintenance technicians, engineers and mechanics all perform essentially the same role. The ICAO defines the licensed role of aircraft maintenance (technician/engineer/mechanic), noting that ' The terms in brackets are given as acceptable additions to the title of the license. Maintenance personnel įield maintenance on a Cessna 172 being conducted from a van used to carry tools and parts

Ī maintenance release can be called a certificate of release to service (CRS). In the case of a certified aircraft this may be an Aircraft Maintenance Engineer or Aircraft Maintenance Technician, while for amateur-built aircraft this may be the owner or builder of the aircraft. Maintenance release Īt the completion of any maintenance task a person authorized by the national airworthiness authority signs a maintenance release stating that maintenance has been performed in accordance with the applicable airworthiness requirements. Bombardier Aerospace offers its Smart Services program, covering parts and maintenance by the hour. GEMCO also offers a similar program for piston engines in general aviation aircraft. Jet Support Services provides hourly cost maintenance programs independently of the manufacturers. Other aircraft engine manufacturers such as General Electric and Pratt & Whitney offer similar programs. It is an option for operators of several Rolls-Royce aircraft engines. Operators are assured of an accurate cost projection and avoid the breakdowns costs the term is trademarked by Rolls-Royce but is the common name in the industry. 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. 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. The term was coined by Bristol Siddeley in 1962 to support Vipers of the British Aerospace 125 business jets for a fixed sum per flying hour. This concept of unscheduled maintenance was initially introduced for aircraft engines to mitigate engine failures. Power-by-the-Hour Ī Power by the Hour program provides budget predictability, avoids installing a loaner during repairs when an aircraft part fails and enrolled aircraft may have a better value and liquidity. 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. Main article: Aircraft maintenance checksĪircraft maintenance in civil aviation generally organized using 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.
