What type of maintenance is referred to as "Phase Inspection"?

A Phase Inspection is a systematic approach to scheduled maintenance and inspection that is designed to ensure the aircraft's airworthiness while minimizing downtime. This type of inspection is typically performed at regular, predefined intervals and covers various aspects of the aircraft's systems and components. Each phase involves checking specific systems and parts, allowing for a comprehensive review of the aircraft’s condition without necessitating the aircraft being grounded for long periods.

This method also helps in identifying potential issues before they lead to significant problems, ensuring safety and operational readiness. It is distinct from inspections that occur only when problems arise or are limited to certain components, as a Phase Inspection encompasses a broader maintenance strategy that aligns with regulatory requirements for aircraft maintenance. By dividing maintenance tasks into phases, it allows for more efficient use of resources and scheduling while keeping the aircraft in optimal condition.
