Explain the maintenance specialty in detail.

Maintenance personnel are professional technicians in airlines, airports and related maintenance enterprises engaged in the maintenance of aircraft airframe, power plant and aviation electrical system, aviation electromechanical and electronic appliances. Aircraft maintenance refers to the service, inspection, testing, repair, replacement, modification and troubleshooting of aircraft or aircraft components, including pre-flight, stopover, post-flight, A-inspection and C-inspection, as well as the work of eliminating the faults reflected by flight crew and aircraft faults and defects found during flight and security inspection. Aircraft maintenance has a wide working area, strong professionalism and high entry threshold.

Due to the shortage of personnel, maintenance personnel have been welcomed by employers in recent years, and the employment rate is extremely high. Shanghai has also experienced high-priced competition. At present, China Eastern Airlines, Shanghai Airlines, Shanghai Airport Group, Singapore Airlines and other domestic and foreign aircraft engine maintenance enterprises are very eager for talents with professional background in aircraft maintenance, and so are other airlines in China. Since last year, domestic airlines have launched large-scale recruitment, among which maintenance talents are the key recruitment positions. Some foreign companies, such as srilankan airlines and Qatar Airways, are also recruiting maintenance personnel. Aircraft manufacturing and maintenance enterprises such as Hafei Aviation Industry Company, Guangzhou Aircraft Maintenance Engineering Co., Ltd. and Xiamen Swire Aircraft Engineering Co., Ltd. often compete with airlines for maintenance talents. As long as people with relevant technology and industry experience can find their favorite positions, after several years of training and efforts, they can become technical personnel and business backbone in the industry.
