Which of the following is NOT a type of TD?

In the context of the Navy Naval Aviation Maintenance Program (NAMP), Technical Directives (TD) are critical documents that provide instructions for maintenance and operation of aviation equipment. The categories of TD include Bulletins, Interim Changes, and Formal Changes, which serve specific purposes relating to updates, modifications, or additional guidance.

Bulletins typically provide urgent information or immediate instructions related to safety or critical repairs. Interim Changes are temporary revisions made to existing directives until a complete and formal change can be issued. Formal Changes represent a more permanent update or modification to existing directives based on ongoing assessments or changes in standards.

Maintenance Records, on the other hand, are documentation that captures the history of maintenance activities performed on naval aviation equipment. These records validate work accomplished, track maintenance needs, and ensure compliance with regulations and procedures. However, they do not fall under the category of Technical Directives since they do not provide direct instructions or modifications to existing systems or procedures.

Thus, Maintenance Records are not considered a type of Technical Directive, making it the correct choice in this scenario. Understanding the distinction between TD types and maintenance documentation is crucial for effective management and operation within the NAMP framework.
