Aircraft maintenance refers to the routine upkeep, repair, and inspection of aircraft to ensure they are in safe and efficient operating condition. This encompasses a range of activities including scheduled maintenance (preventive measures performed at specified intervals), unscheduled maintenance (repairs performed due to malfunction), and modifications or upgrades to systems and components. Aircraft maintenance is critical for ensuring compliance with aviation regulations and safety standards, and it involves careful documentation and adherence to manufacturer’s guidelines. The process is typically carried out by certified maintenance personnel and can include tasks such as checking engines, inspecting airframes, testing avionics systems, and performing structural repairs. Effective aircraft maintenance is essential for prolonging the lifespan of the aircraft, enhancing performance, and ensuring the safety of passengers and crew.
