What defines a Phase Inspection?

A Phase Inspection is defined as a series of related inspections that are performed sequentially at specific intervals. This approach is designed to reduce downtime and streamline maintenance processes by breaking down the inspection into manageable parts. Instead of conducting a comprehensive inspection of the entire aircraft at once, Phase Inspections allow for specific systems or components to be checked regularly and systematically. This method not only helps in maintaining aircraft safety and reliability but also ensures that the aircraft remains serviceable and operational between the more extensive inspections.

This differs from the other options, which refer to either singular inspections, comprehensive annual checks, or inspections based solely on the aircraft's age, lacking the structured, interval-based approach characteristic of Phase Inspections.
