Owning and operating a jet engine doesn’t begin and end with it keeping the aircraft airborne. Like anything else, they have life-limited parts that require maintenance, repair, and replacement over time.
To extend the life of the engine and ensure its reliability and durability, you need to routinely practice jet engine maintenance.
Jet engines are subject to wear from vibration, friction, high interior temperatures, corrosion, and physical damage from the ingestion of foreign debris. All of this paired with the physical stress of rapidly rotating engine parts can cause metal fatigue—and the ultimate failure of the parts as time passes.
Aircraft engine maintenance is essential to the upkeep of the engine and assessing whether jet engine repairs or part replacements are necessary. Maintenance, repair, and overhaul (MRO) operations in the aerospace industry can extend the life of jet turbine blades, vanes, and other aircraft parts, limiting the need for more extensive repairs or replacements.
For example, one reason for performing regular maintenance on jet engines is to ensure that all the rotating stages in an engine are balanced, keeping vibration levels to a minimum. This assists in improving the comfort of aircraft occupants during flight, increasing the engine’s durability, improving fuel efficiency, and limiting the amount of engine wear that occurs from vibration.
Having operations and processes in place for engine maintenance and repairs will assist in actually protecting jet engine parts in the long run.
