What are the two main types of maintenance described in the NAMP?

The two main types of maintenance described in the Naval Aviation Maintenance Program (NAMP) are primarily categorized as rework and upkeep.

Rework refers to that type of maintenance conducted on aircraft and equipment that involves substantial structural or functional repairs, modifications, or alterations. This could involve activities like the major overhauls needed to restore the aircraft to a like-new condition. Rework is typically done outside the regular operational tempo and is essential for maintaining the overall integrity and safety of naval aviation assets.

Upkeep, on the other hand, encompasses the routine maintenance actions necessary to sustain the aircraft or equipment in a serviceable condition during its operational life. This includes preventive maintenance tasks like inspections and servicing that help to minimize wear and catch potential issues before they necessitate rework.

Understanding these two types of maintenance is crucial as they ensure both the immediate and long-term operational readiness of naval aircraft. The distinction between rework and upkeep allows maintenance teams to prioritize tasks effectively and allocate resources properly to maintain fleet capabilities.
