How often are phase inspections conducted?

Phase inspections are systematic examinations of an aircraft conducted at specific intervals established by maintenance standards rather than in response to issues or problems that may arise. This proactive approach ensures that aircraft are maintained in a safe and airworthy condition throughout their lifespan.

Phase inspections are designed to catch potential wear, fatigue, or other maintenance concerns before they become significant problems, fostering overall aircraft reliability and safety. By adhering to a regular schedule defined by industry regulations, which take into account factors like flight hours and cycles, maintenance personnel can manage the aircraft's health in a structured and predictable manner. This approach also allows for better planning of resources and minimizes unexpected downtimes.

In contrast, conducting inspections only when issues arise, after every single flight, or daily as needed would lead to reactive maintenance rather than proactive care, potentially compromising operational safety and efficiency in the long term.
