ENGINEERING & MAINTENANCEMaintenance, repair, and operations (MRO) or maintenance, repair, and overhaul involve fixing any sort of mechanical, plumbing or electrical device should it become out of order or broken (known as repair, unscheduled or casualty maintenance). It also includes performing routine actions which keep the device in working order (known as scheduled maintenance) or prevents trouble from arising (preventive maintenance). MRO may be defined as, "All actions which have the objective of retaining or restoring an item in or to a state in which it can perform its required function. The actions include the combination of all technical and corresponding administrative, managerial, and supervision actions."

Engineering

In telecommunication, commercial real estate and engineering in general, the term maintenance has the following meanings:

1. Any activity – such as tests, measurements, replacements, adjustments and repairs — intended to retain or restore a functional unit in or to a specified state in which the unit can perform its required functions.

2. For material — all action taken to retain material in a serviceable condition or to restore it to serviceability. It includes inspection, testing, servicing, and classification as to serviceability, repair, rebuilding, and reclamation.

3. For material — all supply and repair action taken to keep a force in condition to carry out its mission.

4. For material — the routine recurring work required to keep a facility (plant, building, structure, ground facility, utility system, or other real property) in such condition that it may be continuously used, at its original or designed capacity and efficiency for its intended purpose.

Manufacturers and Industrial Supply Companies often refer to MRO as opposed to Original Equipment Manufacturer (OEM). OEM includes any activity related to the direct manufacture of goods, where MRO refers to any maintenance and repair activity to keep a manufacturing plant running.

Industrial supply companies can generally be sorted into two types:

The ones who cater to the MRO market generally carry a broad range of items such as fasteners, conveyors, cleaning goods, plumbing, and tools to keep a plant running.

OEM supply companies generally provide a smaller range of goods in much larger quantities with much lower prices, selling materials that will be regularly consumed in the manufacturing process to create the finished item.

Maintenance types

Generally speaking, there are three types of maintenance in use:

1. Preventive maintenance

Preventive maintenance is maintenance performed in an attempt to avoid failures, unnecessary production loss and safety violations.

The effectiveness of a preventive maintenance schedule depends on the RCM analysis which it was based on, and the ground rules used for cost-effectively.

2. Corrective maintenance

Corrective maintenance is probably the most commonly used approach, but it is easy to see its limitations. When equipment fails, it often leads to downtime in production. In most cases, this is costly business. Also, if the equipment needs to be replaced, the cost of replacing it alone can be substantial. It is also important to consider health, safety and environment (HSE) issues related to malfunctioning equipment.

Corrective maintenance can be defined as the maintenance which is required when an item has failed or worn out, to bring it back to working order. Corrective maintenance is carried out on all items where the consequences of failure or wearing out are not significant and the cost of this maintenance is much greater than preventive maintenance.

3. Reliability centered maintenance

Reliability centered maintenance is an engineering framework that enables the definition of a complete maintenance regime. It regards maintenance as the means to maintain the functions a user may require of machinery in a defined operating context. As a discipline it enables machinery stakeholders to monitor, assess, predict and generally understand the working of their physical assets. This is embodied in the initial part of the RCM process which is to identify the operating context of the machinery, and write a Failure Mode Effects and Criticality Analysis (FMECA). The second part of the analysis is to apply the "RCM logic", which helps determine the appropriate maintenance tasks for the identified failure modes in the FMECA. Once the logic is complete for all elements in the FMECA, the resulting list of maintenance is "packaged", so that the periodicities of the tasks are rationalized to be called up in work packages; it is important not to destroy the applicability of maintenance in this phase. Lastly, RCM is kept live throughout the "in-service" life of machinery, where the effectiveness of the maintenance is kept under constant review and adjusted in light of the experience gained.

Maintenance on airbus

Airbus actively supports the business success of its customers and contributes to the overall competitiveness of their Airbus aircraft fleet by providing them with top class engineering and technical support.

To help them optimize their aircraft maintenance and reliability, operators are provided with recommendations for aircraft reliability improvements, maintenance costs’ analysis and courses, and above all, with the right technical solutions in a timely manner.

For a more cost effective management of technical documentation, efficient ‘zero paper’ digital technical data solutions are offered that enable airlines to achieve significant cost savings.

To minimize Aircraft-On-Ground time for trouble-shooting or repairs, AIRTAC, a state-of-the art centre with dedicated specialist engineers and fitted with the most innovative technology operates 24 hours, 365 days a year. AIRTAC is part of a wider call centres approach that provides all Airbus operators with a global 24/7 assistance for all Aircraft-On-Ground matters.

In the scope of the “Enhanced support”, a process innovated for A380 customers; AIRTAC is providing analysis and recommendations to customers even before they request it, or before the aircraft lands, through satellite and ground communication networks linking the aircraft, the airline, Airbus and suppliers. “Enhanced Support” helps also improve engineering efficiency by quickly identifying recurrent events and minimizing the time to develop and implement the technical fix.

Airbus network of Maintenance, Repair and Overhaul centres (the Airbus MRO network), which comprises 16 members to date, offers competitive, quality maintenance services to Airbus customers worldwide for all Airbus aircraft families (from the A300/A310 Family to the A380) through extended cooperation with experienced MRO providers.

Already the results of the MRO Network’s first operations have been very positive with customer satisfaction reaching very high levels. Two new members joined the MRO (Maintenance Repair and Overhaul) Network, Mexicana MRO Services and Abu Dhabi Aircraft Technologies.

AVIONICS & SIMULATION

Avionics and Simulation develops and builds systems that optimize aircraft performance, such as fly-by-wire equipment.

As an integral part of Airbus, Avionics and Simulation develops and builds systems that optimize aircraft performance, responsible for providing electronic and software expertise that Airbus business requires.

Avionics and Simulation is dedicated to supply its customers with reliable high-tech products. But it is also an organization qualified for ensuring the high quality services required to get the best of its products all around the world.

It is organized around three complementary product lines: Avionics, Simulation, and Simulation Training Support.

Airbus Avionics and Simulation is consistently ranked amongst the top ten suppliers of Airbus by clients in terms of quality of service.

Avionics and Simulation has developed high-level skills in the disciplines of:

Electronics: high density integration, resistant to extreme weather condition and high reliability. Software: on-board, real-time software at high level of safety Integration of the functions in on-board systems, as well as in the engineering or training

simulators.

QUALITY AND SAFETY FIRST

Delivering aircraft on time on cost and on quality – getting it right first time – drives Airbus policy with safety as number one priority in the design, building and performance of its aircraft.

STRIVING FOR THE HIGHEST STANDARDS

Airbus’ customers expect quality in the aircraft they buy. Safety, reliability, comfort and maintenance costs are key areas where quality is crucial in an airline’s judgment of an aircraft.

To achieve the very highest standards in these and other aspects of an aircraft’s facets and performance the question of quality is addressed by Airbus at every stage from design to final assembly and beyond. Repeated checks are made. Tests are applied. Airbus ensures every supplier of parts meets the strictest standards on quality. Defective work, parts and materials are rejected.

Airbus has a network of key employees who identify problems at various stages of design, production and assembly and recommend action to eradicate them, pre-empting possibly costly delays at a later point. These employees also ensure continuous improvement in standards and efficiency by pinpointing ways in which people could work better or where tools and materials could be improved. As it ramps up production of both single-aisle and long-range aircraft, including the A380, to meet demand, Airbus knows setting even higher standards in quality is critical to maintaining its success.

THE CONSTANT FOCUS ON SAFE OPERATIONS

Around 500 million passengers fly in Airbus aircraft each year. They trust the airlines to get them safely to their destinations. In turn the airlines and other operators trust Airbus. The Airbus name means reliability, quality, and performance. But above all it means safety, the first priority for Airbus.At every point in the design, manufacturing and assembly process Airbus ensures its work complies with certification targets laid down by the European Aviation Safety Authority and the US Federal Aviation Administration.Before an aircraft achieves its final type certificate it must undergo around 1,200 hours of test flying.

But Airbus also works continually in the most effective way to improve the safety of its aircraft: by pro-actively identifying areas and events from which knowledge can be gained. Airbus works with air safety organizations around the world to find new ways of improving standards. Safety is not a matter of competition in the aviation industry. Airbus shares its know-how with others to improve safety for everyone.

European Aviation Safety Agency (EASA)

The European Aviation Safety Agency is a European Union (EU) agency with regulatory and executive tasks in the field of civilian aviation safety. Based in Cologne, Germany, the EASA was created on 15 July 2002, and it reached full functionality in 2008, taking over functions of the Joint Aviation Authorities (JAA). European Free Trade Association (EFTA) countries have been granted participation in the agency.

The responsibilities of EASA include conducting analysis and research of safety, authorizing foreign operators, giving advice for the drafting of EU legislation, implementing and monitoring safety rules (including inspections in the member states), giving type-certification of aircraft and components as well as the approval of organisations involved in the design, manufacture and maintenance of aeronautical products.

As part of Single European Sky II the agency have been given additional tasks. These will be implemented before 2013. Amongst other things, EASA will now be able to certify Functional Airspace Blocks if more than three parties are involved.

Certification

On 28 September 2003, the EASA took over responsibility for the airworthiness and environmental certification of all aeronautical products, parts, and appliances designed, manufactured, maintained or used by persons under the regulatory oversight of EU Member States.

The Certification work also includes all post-certification activities, such as the approval of changes to, and repairs of, aeronautical products and their components, as well as the issuing of airworthiness directives to correct any potentially unsafe situation.

All type-certificates are therefore now issued by the EASA and are valid throughout the European Union. It also carries out the same role for foreign organisations involved in the manufacture or maintenance of such products. The EASA relies on national aviation authorities who have historically filled this role and concludes contractual arrangements to this effect.

FUTURE BY AIRBUS

LOOKING AHEAD

Through innovation, and out-of-the-box thinking, Airbus will continue to meet its eco-efficiency goals, and ensure that air travel continues to be one of the safest, and most eco-efficient, means of transportation.

As the air transport sector continues to grow, Airbus believes that the industry as a whole must concentrate on technological advances, while also advancing solutions that will meet passenger and market demands, the growing population and its demographic profile, and respect all aspects of the environment.After celebrating its own four decades of innovation, Airbus now is looking to the next 40-plus years – actively working with other industry stakeholders and experts to anticipate the global needs of a better-connected and more sustainable world.

However, it all begins with one question: “what will air transport look like in the year 2050?” In its report “The Future by Airbus,” Airbus hypothesises how the industry, aircraft and passengers might change by that time while highlighting potential steps to meet the needs of tomorrow.

SMARTER SKIES CONCEPT

The five key features of Airbus’ Smarter Skies campaign include aircraft takeoff in continuous “eco-climb,” free flight and formation along “express skyways”, free-glide approaches and landings, low-emission ground operations and the use of sustainable biofuels and other potential energy sources.

FUTURE SOLUTIONS

Even a few decades from now, the world will be very different from today. Our lives and travel needs will have changed and, because the global population will increase to over 9 billion, looking after the planet will be even more important than ever.

In the past, air travel has mainly focused on getting people to their destination in the safest and fastest way possible. In the future, however, travelling could be an entirely different experience – integrating different stages of the journey or possibly changing how passengers pay, and making the excursion so enjoyable that passengers may want a trip to last even longer.

Airbus Concept Plane Aircraft carriers

The Airbus Concept Plane stretches the imagination of engineers, and illustrates the main technologies being explored in anticipation of the future needs of passengers.

Hundreds of flights already take place on popular long-distance routes like from Europe to the U.S., Asia or Australia and there will be a lot more by 2050.

So, instead of operating dozens of separate flights, perhaps airlines could have giant aircraft carriers. Smaller aircraft could dock on them for most of the journey – perhaps using vertical take-off and landing techniques – then be deployed on more localized shuttle service at either end of the trip.

The size of these new-generation aircraft carriers might even open up new possibilities for the type of energy that could be used to power them.
