Civil aircraft maintenance application project

The civil aircraft maintenance application project is a complex and multi-layered field, which covers multiple stages from routine inspection to complete dismantling and overhaul to ensure the safe and reliable operation of the aircraft. The following is a detailed summary of civil aircraft maintenance application projects:

1. Maintenance process

Routine inspection

Brief inspection and maintenance of the aircraft's appearance, instrumentation and avionics before and during each takeoff and landing.

Inspection items: including appearance inspection (fuselage, wings, tail and landing gear, etc.), instrument inspection (barometer, temperature gauge, oil pressure gauge, etc.) and avionics inspection (communication equipment, navigation equipment and flight control system, etc.).

Executive: Usually done by both the pilot and ground crew.

Time: It usually takes between 30 minutes and 1 hour.

A test

Cycle: Every 300 to 500 hours of flight time or once a month.

Contents: Includes appearance inspection of fuselage, wings and tail, landing gear and tire inspection, engine inspection, as well as instrumentation and avionics equipment inspection.

Location: Take place in the hangar or maintenance area of the airport.

Time: Usually takes between 4 and 8 hours.

B test

Cycle: every 600 to 800 hours of flight time or every six months.

Content: In addition to the content of the A inspection, it also includes the structural inspection of the wings and fuselage, as well as the inspection of the flight control system.

Location: Also in the hangar or maintenance area of the airport.

Time: Usually takes 2 to 3 days.

C check

Content: Further in-depth examination of the various systems of the aircraft, including the inspection of the hydraulic and fuel systems.

Time: It usually takes 7 to 10 days.

D examination

Cycle: Every 6 to 10 years.

What: A complete dismantling and overhaul of the aircraft, including a complete dismantling and inspection of the fuselage, wings, tail and engines.

Time: Usually takes a few weeks.

2. Maintenance technology

Mechanical maintenance

Contents: Maintenance and overhaul of fuselage, wing, tail, landing gear and other parts, including sheet metal maintenance, welding maintenance, machining and landing gear maintenance.

Electronic maintenance

Content: Maintenance and overhaul of various electronic equipment of the aircraft, such as radar, communication equipment, navigation equipment, autopilot system, etc. Including fault diagnosis, circuit maintenance, equipment calibration and software updates.

Hydraulic maintenance

Content: Maintenance and overhaul of the aircraft's hydraulic system, including oil line maintenance, oil pump maintenance and fuel tank maintenance.

Fuel system maintenance

Maintenance and overhaul of aircraft fuel systems, including the repair and replacement of fuel pumps, fuel filters and fuel nozzles.

3. Special application projects

Application of RFID technology in aircraft maintenance

Management of maintenance tools: The use of RFID technology to achieve visual, real-time and dynamic management of maintenance tools to improve maintenance efficiency.

Component management: Tracking and managing the status of aircraft components through RFID technology to ensure timely replacement and maintenance of components.

New technology application

With the development of science and technology, more and more new technologies are applied to aircraft maintenance, such as UAV appearance inspection, big data analysis to predict faults, etc., in order to improve the accuracy and efficiency of maintenance.
