These major inspections and overhauls take place at predetermined intervals, typically every few years. During these inspections, the aircraft is thoroughly examined, and components are replaced as necessary according to established guidelines.

One critical aspect of these extensive inspections is the examination of the aircraft’s structure. Highly trained inspectors carefully inspect the fuselage, wings, and tail section for any signs of corrosion, stress fractures, or other structural abnormalities. They use advanced non-destructive testing techniques, such as ultrasound and X-rays, to identify hidden defects that may not be visible to the naked eye.

In addition to the structural and system inspections, the check team also focuses on the aircraft’s components. This includes the landing gear, engines, and control surfaces. Landing gear undergoes a thorough examination, with technicians checking for any signs of wear, corrosion, or hydraulic leaks. Engines are inspected for any abnormalities, such as oil leaks or worn-out parts, and necessary repairs or replacements are made to ensure optimal engine performance. At this point, we have evidence that answering the question of how often airplanes get maintenance is not an easy task as it depends on many influencing factors.

Major Inspections and Overhauls

Major inspections and overhauls are pivotal elements in the world of plane maintenance. During these major inspections, every facet of the aircraft is meticulously examined, from its engines and avionics to its structural integrity. Should any issues or indications of wear and tear be detected, extensive repairs or component replacements are undertaken to restore the aircraft to peak performance. These procedures are absolutely essential for aviation safety and are tightly regulated by authorities to uphold rigorous maintenance standards.

Heavy Maintenance Checks

Heavy maintenance checks, often referred to as “C-checks” or “D-checks,” represent a specialized subset of major inspections. These checks are more extensive and time-consuming, requiring the aircraft to be taken out of service for an extended period of time. Heavy maintenance checks are typically scheduled after a specific number of flight cycles and encompass a thorough evaluation of the aircraft’s systems, components, and structures. During these checks, various parts are disassembled, meticulously inspected, and replaced as necessary.
