How is maintenance defined in the context of aviation?

Maintenance in the context of aviation is a comprehensive approach designed to keep aircraft in a safe and functional state. It encompasses several critical activities such as inspection, overhaul, repairs, preservation, and part replacement. This definition reflects the multifaceted nature of maintenance, ensuring not only that aircraft are routinely examined for safety and functionality but also that any required repairs and updates are adequately performed to maintain airworthiness.

This broad scope is essential because aviation safety is paramount. Regular inspections help catch potential issues before they develop into serious problems, while overhauls and repairs address any defects or wear that could compromise safety. Preservation activities ensure that aircraft components maintain their integrity over time, and part replacement is crucial when components have reached the end of their service life or do not meet the necessary safety standards.

In this context, focusing solely on routine checks and inspections, on non-functional aircraft only, or just preventive measures before flight would not encapsulate the complete definition of maintenance in aviation, which requires a well-rounded strategy to ensure the overall safety and effectiveness of aircraft operations.
