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.

The process used by the TAA for establishing acceptability of the work and artefacts of another airworthiness regulatory authority is called recognition. Finally, in the military context, recognition can improve flexibility and capacity during joint operations.

Safety and airworthiness are sovereign responsibilities. Recognition, therefore, does not transfer any airwotthiness responsibilities from the TAA to the recognized AA.

Furthermore, TAA recognition of another AA neither implies, nor requires, that the authority must make any changes to their airworthiness management systems as a result of the recognition.

It remains the responsibility of the Qirworthiness 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:.

There are currently a number of initiatives aimed at harmonizing the approach to airworthiness regulation between MAAs and for achieving mutual recognition. Key coordinated efforts have been sponsored by:. Common to airwothiness efforts between these agencies is the use of a aireorthiness assessment tool, based on ICAO documents references g. This standardized assessment tool has been tailored for the military context and takes the form of a airwortjiness set called the Military Authorities Recognition Question set MARQ reference i.

Within a military organization, airworthiness and aviation responsibility may be spread across a number of organizations, and enforcement may only be possible through internal regulations, rules and contracts. While MAAs may closely align with many of the international civilian airworthiness processes, by necessity, military aviation has a different risk context mahual will employ military design standards.


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

TAA Advisory – Recognition of Airworthiness Authorities

Military Authorities Recognition Question Airworthineds. The four sub-sections are:. The recognition process follows four basic phases:. 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. When granting recognition, the TAA will specify any associated terms or condition. Sustainment usually relates to the requirement to communicate any manua to the conditions under which the recognition was originally issued.

Terms, conditions and sustainment requirements mannual normally articulated in a recognition certificate and the supporting documentation. The planning phase is used to review the rationale for the AA recognition and establish the recognition plan. The recognition plan can be used airwogthiness provide the rationale for a direct recognition, without completion of the MARQ or an onsite evaluation.

It may be necessary to develop limitations and conditions associated with the recognition, based upon risk assessment of any gaps in documentation or information. 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 report provides an overall assessment of acceptability and identifies any areas that require clarification through an onsite review. DTAES 2 maintains a record of individual evaluator findings and coordinates with the AA being assessed to build a schedule for the aiwrorthiness review.

A recognition does not expire. Information is provided related to:. Manal stated in para 4. Reference j represents a TAA staff instruction that covers how companies providing services under contract to DND are recognized. Recognition of Airworthiness Authorities Effective Date: The generic term for any of the following: The government statutory authority in each country that oversees the approval and regulation of civil aviation.

Depending on how it is structured within the state, the airworthiness authority may be established as a sub-component of the larger Civil Aviation Authority.


The national military airworthiness authority of a state responsible for the airworthiness of the military aircraft of that state. Other military regulators may be organized differently, for example: For the purposes of this advisory, recognition is defined as the process by which an AA assesses and acknowledges another AA as being a competent regulator, empowered with the necessary authority, infrastructure, resources and mechanisms to ensure aviation safety.

The scope of recognition is limited to those airworthiness functions that fall within the assigned responsibility of the respective AA. For the DND TAA and the Technical Airworthiness Program, this relates to airworthiness certification, production oversight and airworthiness inspection continuing airworthiness.

Recognition can be unilateral, bilateral or multilateral. For the purpose of this advisory, an airworthiness artefact is a work product from a military or civil airworthiness authority.

Normally, airwothiness work products will have received an airworthiness approval or other form of authorization from an AA. Examples may include any of the following: 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 dc 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.

Limitations and Constraints 4. Recognition — Civil Aviation Authorities 4. This also includes acceptance of TCCA organizational approvals related to maintenance, design, manufacturing and materiel support services for civil-derived aeronautical products; and U.

This also includes acceptance of FAA organizational approvals related to maintenance, design, manufacturing and materiel support services for civil-derived aeronautical products. The process by which the TAA will undertake this recognition could include:
