A Guide to Aircraft Maintenance
Aircraft owners or owners of airline companies should make sure that their aircrafts are subjected to regular maintenance and inspection so that the aircrafts perform well and are safe to use. Aircrafts are vehicles which are complicated, and you need professionals to do the maintenance work in several different ways so that you can be sure that all the parts of the aircraft can operate properly. Here are the different phases of maintenance and inspection that an aircraft undergoes.
The basic mechanical structure of an aircraft is called the airframe. The fuselage, the wings, and the undercarriage make up the airframe. Airframe maintenance does not focus on all the aircraft parts but only the components of the airframe, so the engine or the propulsion system is not included in this work. Tasks such as winglet inspection and replacement, corrosion prevention and control, painting the aircraft, and landing gear replacement are all involved in the maintenance of the airframe. Letter checks is another type of maintenance performed on an aircraft. When an aircraft has flown a specific number of miles, these letter checks which are detailed inspections done on the aircraft, are done to the aircraft. Cosmetic A and B checks, intensive C checks of all components, and D check which is the dismantling and reassemebling of the aircraft, are all procedures in the letter check. A and B checks are frequently done but C and D checks which are time consuming are done only every few years.
One important aspect of aircraft maintenance is the maintenance of its engine. Your aircraft has a specific engine type so you need a mechanic who specializes in this engine type. There are many things involved in engine work. These works include comprehensive testing of the engine, engine removal and reinstallation, and engine troubleshooting. The aircraft’s APU or auxiliary power unit should also be subjected to regular check and maintenance. The APU powers the aircraft so that it can function properly but this is not propulsion. APUs have specific make and model and the mechanic that will do the maintenance work should have been trained with these types of APU.
Aside from these there are other aircraft components that need to be checked and, if necessary, repaired. If these other components are subjected to a full scale component check what will be done are the following: removing and cleaning the components, applying compounds to prevent corrosion, lubrication of parts, and replacement of damaged parts.
The electronic systems or avionics are very important parts that has a great bearing on an aircraft’s performance. Navigation and communication equipment including GPS, radar, radio communicators, and computer systems are included in the testing of the avionics. What is involved in avionic system maintenance are the rewiring and replacement of components, and requires a mechanics with electrical engineering background.
