Aircraft maintenance is the performance of tasks required to ensure the continuing airworthiness of an aircraft or aircraft part , including overhaul, inspection, replacement, defect rectification, and the embodiment of modifications, compliance with airworthiness directives and repair. The maintenance of aircraft is highly regulated, in order to ensure safe and correct functioning during flight. In civil aviation national regulations are coordinated under international standards, established by the International Civil Aviation Organization ICAO.

The ICAO standards have to be implemented by local airworthiness authorities to regulate the maintenance tasks, personnel and inspection system. Maintenance staff must be licensed for the tasks they carry out. Aircraft 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.

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. A 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.

This concept of unscheduled maintenance was initially introduced for aircraft engines to mitigate engine failures. In the s, 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 the breakdowns costs; the term is trademarked by Rolls-Royce but is the common name in the industry.

Jet Support Services provides hourly cost maintenance programs independently of the manufacturers. At 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.

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. Each Contracting State is expected to use in its own regulations the one it prefers. However different countries use these terms in different ways to define their individual levels of qualification and responsibilities.

This regulation establishes four levels of authorization:. Its is projected to grow at 4. Shared data-supported predictive maintenance can reduce operational disruptions. Insourced maintenance can be inefficient for small airlines with a fleet below 50—60 aircraft. They have to either outsource it or sell its MRO services to other carriers for better resource utilization. As an aircraft gets older, a greater percentage of its value is represented by its engines.

Over the course of the engine life it is possible to put value back in by repair and overhaul , to sell it for its remaining useful time, or to disassemble it and sell the used parts, to extract its remaining value. Its maintenance value includes the value of life-limited parts LLPs and the time before overhaul.

The core value is the value of its data plate and non-life-limited-parts. After some time the maintenance reserves exceed the aircraft lease. Between and , 5, spare airliner engines will be required with at least half leased. Airbus has indicated that data diagnostics could put an end to aircraft unscheduled grounding for fault repairs around , supported by big data and operational experience.

Predictive maintenance , diagnostics and health monitoring could eliminate unscheduled groundings, by making maintenance schedule intervals more frequent to avoid AOGs and the associated operational interruptions, ultimately eliminating them. Data or monitoring can tell that some parts do not need a scheduled check, but a full transition to this model will need much greater experience.

With more history, examples and regulatory confidence, the maintenance program and associated manuals could become a dynamic documents for each specific aircraft with maintenance schedule based on operational history of the aircraft. All-electric is sometimes selected for sub seats commuters, and more often for smaller seat aircraft like urban air taxis or trainers.

Electric motors will probably require less maintenance than a fuel engine, while batteries and cables may need to be exchanged more often than fuel systems. A Britten-Norman Islander retrofitted with electric propulsion should be demonstrated by by Cranfield Aerospace before commercial service in Automated aircraft inspection systems have the potential to make aircraft maintenance safer and more reliable.

What is MRO and What Does it Stand For? A Brief Guide to Maintenance, Repair, and Operations

Helen Carey. The term MRO is an acronym that stands for maintenance, repair, and operations. In this article, a review of MRO activities will be discussed against the overall operations and supply chain management functions that exist to run a business on a day-to-day basis. If you consider a manufacturing plant or facility as an example, there are a variety of different operations and activities that take place within that facility on a daily basis. Production lines are operating which take materials and parts from suppliers and machine them or assemble them those into finished goods that are the main output of the business. Incoming shipments of materials and outgoing shipments of finished products are being managed.

Он будет стрелять с бедра, направляя дуло вверх, в спину Беккера. Пуля пробьет либо позвоночник, либо легкие, а затем сердце. Если даже он не попадет в сердце, Беккер будет убит: разрыв легкого смертелен. Его, пожалуй, могли бы спасти в стране с высокоразвитой медициной, но в Испании у него нет никаких шансов.

Она кружила по пустому кабинету, все еще не преодолев ужас, который вызвало у нее общение с Хейлом. Надо выбираться из шифровалки. Черт с ней, с Цифровой крепостью. Пришла пора действовать.
