Aerospace and Airline in India.

Aerospace-industry companies typically provide maintenance services for corporate, commercial, and military aircraft. Light-plane maintenance is typically done by local fixed-base operators who are not affiliated with the aerospace industry. Although launch vehicles and uncrewed spacecraft are constantly checked and corrected during their pre launch life, they are single-use systems. Crew safety is the most important consideration for crewed spacecraft. Every trip of the space shuttle, for example, is extensively examined by NASA and contractor staff. Specialists in their operating units maintain small military missiles in the field. Ballistic missiles are subjected to routine maintenance at their field sites, however some tasks, such as realignment of structure and sensors, necessitate the missile’s return to the originating plant.

The civil or military operator is usually in charge of routine aircraft maintenance. It involves routine inspections, such as replacing a part or repairing a faulty piece of equipment, and minor maintenance, such as replacing a part or repairing a faulty piece of equipment, after each flight, a set series of flights, or a time interval. Most aeroplane terminals and military bases can handle this type of maintenance. Major maintenance work includes a comprehensive overhaul of an aeroplane or engine that has seen a lot of use. Larger airlines, as well as major military aviation units, have their own extensive technical facilities for major refurbishment. In order to attain a high level of skill and efficiency, these facilities usually specialise in servicing specific models. 

Despite their competitiveness in the air, smaller airlines frequently collaborate on the ground and hire other carriers’ technical services to perform maintenance. Maintenance services are provided by some manufacturers through subsidiaries that specialise in this field. The costs of maintaining aeronautical systems are significant. For example, an operator will spend around two to three times the original acquisition cost on maintenance during the life of a typical jet engine.

The real manufacturer’s role in product maintenance is mostly that of a supplier of parts, paperwork, and guidance. Original equipment manufacturers rely heavily on the sale of spare parts as a source of revenue. Boeing, for example, sends out over 650,000 spare parts to approximately 400 airlines each year. The company’s main spare-parts centre has 410,000 distinct parts—a total of 50,000,000 items—and is open 24 hours a day. The provision of electronic documentation is becoming standard practice.
