Which division is responsible for I-level maintenance?

The division responsible for I-level maintenance is the 400 Division. I-level maintenance, or intermediate-level maintenance, is focused on ensuring that aircraft and systems are operationally ready and safe for flight. This level of maintenance provides a balance between the more in-depth D-level (depot-level) maintenance and the more routine O-level (organizational-level) maintenance, ensuring that equipment receives necessary repairs and services to sustain its performance.

The 400 Division typically aligns with this I-level maintenance function by overseeing tasks such as troubleshooting, repairs, adjustments, and on-site modifications. This division plays a critical role in maintaining the readiness of aircraft systems, which directly impacts the operational effectiveness of naval aviation.

While other divisions may perform maintenance tasks or support roles, the specific responsibilities around I-level maintenance are distinctly aligned with the 400 Division. Understanding this division's role is crucial for personnel in the aviation community as it emphasizes the need for proper maintenance conditioning and operational readiness.
