A Guide to Aircraft Maintenance
Aircrafts should be maintained and inspected regularly so that it will always be in good flying condition. Because aircrafts are complicated vehicles there is a need for professionals to do the maintenance and inspections which is done in many different ways for its many different parts.
Here are the types of maintenance that need to be performed for any aircraft.
The airframe is the basic mechanical structure of the aircraft including the fuselage, its wings, and undercarriage. When we speak of airframe maintenance the main focus are these areas are not the engine or propulsions system. Inspection and replacement of winglets, prevention and control of corrosion, painting, and landing gear replacement are the basic maintenance works performed on an aircraft’s airframe. After travelling a specific number of miles in the air, there is a kind of maintenance which involve detailed inspections which are called ‘letter checks’. The components of this letter checks include cosmetic A and B checks, an intensive C check of all components, and a D check where the aircraft is taken apart and reassembled. The frequently done checks are the cosmetic A and B checks while the C intensive check and the D dismantling and reassembling, involves a lot of time and are only done every few years.
The other types of maintenance that are also extremely important for aircrafts are the engine and APU (Auxiliary power unit) maintenance. Since this is a highly specialized maintenance work, it takes a mechanic that specializes in the specific engine type of the aircraft, to do the task. Engine maintenance involves a lot of tasks including the following: comprehensive engine testing, removal and reinstallation, and troubleshooting. There is also a need to check and regularly maintain the aircraft’s APU. For functions not related to propulsion, it is the APU that provides the aircraft’s power. A specialized mechanic is needed to do this maintenance work; someone who is well versed in fixing the specific make and model of the APU.
There are other aircraft parts that need to be check and repaired, if necessary. These are the activities involved in a complete aircraft components’ check: removing and cleaning components, applying anti-corrosion compounds,lubricating parts, and replacing parts that are damaged. To make sure that all pneumatic and hydraulic systems are running smoothly, the technician will also run tests on them.
Avionics or aircraft electronics are very important factors in an aircraft’s overall performance. The focus of avionics testing and maintenance are all the navigation and communication equipment of the aircraft which includes GPS, radar, radio communications, and computer systems. The technician will rewire and replace components when needed. For this type of maintenance job, the mechanics has to be one with a strong technical knowledge of electrical engineering. We see here that aircraft maintenance is a process which is extensive and multifaceted. These are the stages of maintenance that every aircraft owner should understand so that they will known the condition of the aircraft and its performance capability.
