Where is scheduled maintenance typically explained?

Scheduled maintenance is typically explained in the Maintenance Planning Document (MPD). The MPD serves as a comprehensive guide that outlines the maintenance requirements and procedures for an aircraft over its operational lifespan. It includes details about inspection intervals, scheduled checks, and other essential maintenance actions that must be carried out to ensure the aircraft's airworthiness and safety.

This document is crucial for maintenance personnel as it helps them plan and schedule necessary maintenance activities, aligning them with regulatory requirements and manufacturer specifications. By detailing the timeline and scope of maintenance tasks, the MPD helps ensure efficient aircraft operations and compliance with safety regulations.

While the Aircraft Operations Manual provides information on operating procedures, flight safety protocols, and general aircraft operation, it does not typically delve into specific maintenance requirements. Similarly, the Airline's Safety Protocols focus more on safety measures and emergency procedures rather than routine or scheduled maintenance tasks. The Aircraft's Service History documents the past maintenance activities performed on the aircraft, but it does not provide a structured plan for future maintenance, which is the primary purpose of the Maintenance Planning Document.
