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.

Recognition can be unilateral, bilateral or multilateral. The ultimate responsibility for continued airworthiness is assigned in ICAO Annex 8 to the State of Design but the programme to achieve continuing airworthiness is a matter for the State of Registry.

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.

Retrieved from ” https: 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. 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.

Recognition, therefore, does not transfer manuxl legal responsibilities from the TAA to the recognized AA. Although the owner bears the legal responsibility for continuing airworthiness, there is very much a shared responsibility between:.

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


Continuing Airworthiness is therefore not just the maintenance of aircraft and equipment, but also involves monitoring performance of products in service.

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 airowrthiness other than the TAA. Recognition — Civil Aviation Authorities 4.

It may be necessary to develop limitations and conditions associated with the recognition, based upon risk assessment of any gaps in documentation or information. There are currently a number of initiatives aimed at harmonizing the approach to airworthiness regulation between MAAs and for achieving mutual recognition.

TAA Advisory – Recognition of Airworthiness Authorities

A recognition does not expire. Finally, in the military context, recognition airworthijess improve flexibility and capacity during joint operations. Timely response is required where airworthiness is affected, which means devising and provisioning rectification action, and promulgating the necessary information to restore safety levels. 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.

When granting recognition, the TAA will specify any associated terms airwoorthiness condition. The recognition process follows four basic phases:. Examples may include any of the following: This also includes acceptance of TCCA organizational approvals related to maintenance, design, manufacturing and materiel support services for civil-derived aeronautical products; and U.

Reference should also be made to M. This also includes acceptance of FAA organizational approvals related to maintenance, design, manufacturing and materiel support services 7960 civil-derived aeronautical products. The planning phase is used to review the rationale for the AA recognition and establish the recognition plan.


Sustainment usually relates to the requirement to communicate any change to the conditions under which the recognition was originally issued. Recognition of Airworthiness Authorities Effective Date: Common to the efforts between these agencies is the use of a standardized assessment tool, based on Airwortniness documents references g. Once the regulatory Section Heads have completed their reviews, they provide a summary of their findings to DTAES 2, airworthinesss collates them into a preliminary report.

This standardized assessment tool has been tailored for the military context and takes the form of a question set called the Military Authorities Recognition Question set MARQ reference i.

Military Authorities Recognition Question Set. 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.

Reference j represents a TAA staff instruction that covers how companies providing services under contract to DND are recognized. In the words of ICAO:.

Furthermore, TAA recognition of another AA neither implies, nor requires, that the authority must make any changes to their airworthiness management dco as a result of the recognition. Safety and airworthiness are sovereign responsibilities.

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. 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.

This is an approved organisation responsible for implementation of continuing airworthiness management tasks. Other military regulators may be organized differently, for example: As stated in para 4.
