What maintenance level is performed by designated maintenance activities supporting operating units?

The maintenance level performed by designated maintenance activities supporting operating units is known as Intermediate Level Maintenance, or I-level. This level of maintenance is critical because it serves as a bridge between organizational maintenance, which is performed at the operational level, and the more extensive depot-level maintenance, which involves major overhauls and repairs.

I-level maintenance focuses on tasks that can be performed at the maintenance facility to ensure that equipment and systems are operational and reliable. These tasks often include repair, calibration, and major component replacement, typically addressing issues that cannot be resolved at the operational or O-level.

This categorization of maintenance levels helps streamline maintenance operations for each specific unit, allowing for more efficient and effective support to ensure aircraft readiness and reliability in operational contexts.
