Purpose, in the publication’s words

Department of Defense (DoD) policy requires all air systems owned, leased, operated, used, designed, or modified by DoD to have an airworthiness assessment and approval. (T-0) The Technical Airworthiness Authority (TAA), or their delegated technical authority (DTA), performs an airworthiness assessment for the configuration, usage, and operating environment which supports the issuance of an airworthiness approval. If the flight activity has an existing approval from another airworthiness authority recognized by the TAA (e.g., the Federal Aviation Administration or (FAA)), the TAA’s assessment begins with an evaluation of existing approvals to gain a full understanding of the certification baseline and the intended configuration, usage, and operating environment. This instruction contains the processes to conduct assessments and obtain and maintain airworthiness approvals of air systems throughout their lifecycle, enabling safe operations throughout the DAF.
