There are currently a number of initiatives aimed at harmonizing the approach to airworthiness regulation between MAAs and for achieving mutual recognition. While MAAs may closely align with aiworthiness of the international civilian airworthiness processes, by necessity, military aviation has a different risk context and will employ military design standards. Normally, these work products will have received an airworthiness approval or other form of authorization from aitworthiness AA.

Furthermore, there is no airwoethiness, internationally recognized organization that sets ajrworthiness or harmonizes the military airworthiness and aviation requirements of MAAs.


Once the regulatory Section Heads have completed their reviews, they provide a summary of their findings to DTAES 2, who collates them into a preliminary report. It may be necessary to develop limitations and conditions associated with the recognition, based upon risk assessment of any gaps in documentation or information. To enable the provisions of these two TAM dic, there is a requirement to identify the other regulatory aireorthiness that are acceptable to the TAA and detail the methodology used to establish acceptability.

Reference should also be made to M. Terms, conditions and sustainment requirements are normally articulated in a recognition certificate and the supporting documentation.
