What does the term “overhaul” mean in aviation maintenance?

The term "overhaul" in aviation maintenance specifically refers to a comprehensive inspection, repair, and upgrade of a component. This process often involves disassembling the component to examine its internal parts, replace worn or damaged elements, and ensure that it meets the relevant safety and operational standards. Overhauls are typically performed on critical components such as engines or landing gear to extend their operational life and enhance their performance.

In the context of aviation maintenance, overhauling is much more involved than routine check-ups or minor repairs. It requires detailed attention and specialized knowledge to completely refurbish a component, which not only restores it to a serviceable condition but often upgrades its capabilities to meet modern specifications.
