Which levels of maintenance are recognized in the Army aviation structure?

The recognized levels of maintenance in the Army aviation structure are Field and Sustainment Maintenance. This classification is essential for effective maintenance management and is structured to support the operational readiness of aviation units.

Field Maintenance refers to the repairs and maintenance conducted at the unit level, ensuring that aircraft and equipment are operational and capable of performing their missions. This level emphasizes routine checks, minor repairs, and servicing that can be accomplished by unit personnel with appropriate training and equipment.

Sustainment Maintenance, on the other hand, occurs at a higher level, typically involving more complex repairs and overhauls. This level is executed at maintenance depots or facilities where specialized skills and resources are available. Sustainment Maintenance ensures that the equipment remains operational over the long term and can address significant repairs that exceed the capability of Field Maintenance.

By clearly defining these two levels, the Army provides a structured approach to maintenance that enhances the effectiveness and efficiency of aviation operations while supporting overall mission readiness.
