What are the two types of maintenance in the NAMP?

In the context of the Naval Aviation Maintenance Program (NAMP), the correct classification of maintenance into two types is based on the concepts of Rework and Upkeep.

Rework refers to the more extensive maintenance activities that are necessary to create a material condition that meets the required specifications. This type of maintenance typically occurs at the organizational level and can involve significant work such as overhaul and repair to restore an aircraft or equipment to optimal operational status.

On the other hand, Upkeep includes less extensive maintenance tasks that are routine and preventive in nature. These activities are essential for keeping systems operational and ensuring that aircraft maintenance is sustained throughout their lifespan.

Understanding the difference between these two types clarifies how the maintenance process is structured under the NAMP to ensure safety, reliability, and efficiency in naval aviation operations.
