It remains the responsibility aurworthiness the TAA to account for any differences in standards and processes, and to decide how any identified gaps are to be managed. The process by which the TAA will undertake this recognition could include: Key coordinated efforts have been sponsored by:. This standardized assessment tool airworthoness been tailored for the military context and takes the form of a question set called the Military Authorities Recognition Question set MARQ reference i.

Timely response is required where airworthiness is affected, which means devising and provisioning rectification action, and promulgating the necessary information to restore safety levels.

For each of its aircraft, the approved Airworghiness is required to carry out the following functions. Terms, conditions and sustainment requirements are normally articulated in a recognition certificate and the supporting documentation.

A recognition does not expire. Recognition can be unilateral, bilateral or multilateral.

The process used by the TAA for establishing acceptability of the work and artefacts of another airworthiness regulatory authority is called recognition. Recognition, therefore, does not transfer any legal responsibilities from the TAA to the recognized AA.

The process by which the TAA will undertake this recognition could include:. The four sub-sections are:. The recognition plan can be used to provide the rationale for a direct recognition, without completion of the MARQ or an onsite evaluation. DTAES 2 maintains a record of individual evaluator findings and coordinates with the AA being assessed to build a schedule for the onsite review.


When granting recognition, the TAA will specify any associated terms or condition. TAM Part 1, Chapter 4 — Assignment of Technical Airworthiness Authority describes the rules and standards for determining the acceptability of organizations that have been assigned airworthiness management roles or airworthiness functions by a regulatory authority other than the TAA.

TAM Part 2, Chapter 5 — Type Design Examination TDE describes the rules and standards for the acceptance of work performed, and airworthiness artefacts issued, by other airworthiness authorities in relation to initial type certification or major design change approval.

For the DND TAA and the Technical Airworthiness Program, this relates to airworthiness certification, production oversight and airworthiness inspection continuing airworthiness. In the words of ICAO:. Common to the efforts between these agencies is the use of a standardized assessment tool, based on ICAO documents references g. While the review process includes both a desktop and an onsite review, the output of the desktop review can be sufficiently comprehensive to preclude the requirement for the onsite review.

Information is provided related to:. To enable the provisions of these two TAM chapters, there is a requirement to identify the other regulatory authorities that are acceptable to the TAA and detail the methodology used to establish acceptability.

This also includes acceptance of FAA organizational approvals related to maintenance, design, manufacturing and materiel support services for civil-derived aeronautical products.

Continuing Airworthiness management is the process by which an aircraft is kept in a condition where it remains airworthy throughout its life – or in other wordsi.

Limitations and Constraints 4. There are currently a number of initiatives aimed at harmonizing the approach to airworthiness regulation between MAAs and for achieving mutual recognition.

The generic term for any of the following: Normally, these work products will have received an airworthiness approval or other form of authorization from an AA. 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.

The scope of recognition is limited to those airworthiness functions that fall within the assigned responsibility of the respective AA. For example, for most military organizations, operational effectiveness is paramount and, therefore, aviation safety objectives must be balanced against the need to accept higher levels of risk wherever operational circumstances dictate.

Continuing Airworthiness is therefore not just the maintenance of aircraft and equipment, but also involves monitoring performance of products in service. Safety and airworthiness are sovereign responsibilities. Furthermore, there is no single, internationally recognized organization that sets standards or harmonizes the military airworthiness and aviation requirements of MAAs.

The government statutory authority in each country that oversees the approval and regulation of civil aviation. It may be necessary to develop limitations and conditions associated with the recognition, based upon risk assessment of any gaps in documentation or information.

Cranfield University Publication Authority: Reference should also be made to M. The report provides an overall assessment of acceptability and identifies any areas that require clarification through an onsite review.

While MAAs may closely align with many of the international civilian airworthiness processes, by necessity, dic aviation has a different risk context and will employ military design standards. Aidworthiness on how mznual is structured within the state, the airworthiness authority may be established as a sub-component of the larger Civil Aviation Authority.

Finally, in the military context, recognition can improve flexibility and capacity during joint operations.
