Which level of maintenance provides direct support to both O-Level and I-Level?

The correct answer is Depot Level Maintenance, as this level serves as a comprehensive support structure that encompasses both Organizational Level (O-Level) and Intermediate Level (I-Level) maintenance activities. Depot Level Maintenance is typically conducted at more centralized locations and is responsible for the extensive repair, overhaul, or rebuilding of aircraft, systems, and subsystems.

These facilities are often equipped with specialized tools and equipment necessary to perform complex repairs and maintenance tasks that go beyond the capabilities of O-Level and I-Level maintenance. While O-Level focuses on the day-to-day maintenance and operational readiness of aircraft, and I-Level is responsible for more in-depth inspections and repairs, Depot Level Maintenance steps in to provide critical support through its advanced technical expertise and resources.

This ensures the overall operational capabilities of the fleet are maintained at a higher standard, allowing O-Level and I-Level to focus on their specific roles effectively.
