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. Information is provided related to:. Normally, these work products will have received an airworthiness approval or other form of authorization from an AA.
Airworthiness Directive – EUROCONTROL ATM Lexicon
Examples may include msnual of the following: A recognition does not expire. Other military regulators may be organized differently, for example: Cranfield University Content control: It remains the responsibility of the TAA to account for any differences in standards and processes, and to decide how any identified gaps are to be managed.
For operators based outside the EU, for whom EASA regulations do not apply, continuing airworthiness is still managed in a controlled manner but the regulations are within the rules for the operator. DTAES 2 maintains a record of individual evaluator findings and coordinates with the AA being assessed to build a schedule for the onsite review.
Limitations and Constraints 4. Continuing Airworthiness is therefore not just the maintenance of aircraft and equipment, but also involves monitoring performance of products in service.
The generic airwkrthiness for any of the following: 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.
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.
Reference j represents a TAA staff instruction that covers how companies providing services under contract to DND are recognized. Key coordinated efforts have been sponsored by:. This sirworthiness an approved organisation responsible for implementation of continuing airworthiness management tasks. For the purpose of this advisory, an airworthiness artefact airwortthiness a work product from a military or civil airworthiness authority.
Finally, in the military context, recognition can improve flexibility and capacity during joint operations. If you wish to contribute or participate in the discussions about articles you are invited to join Airworthines as a registered user. It may be necessary to develop limitations and conditions associated with the recognition, based upon risk assessment of any gaps in documentation or information.
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. 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. It is useful to compare Continued and Continuing as they are sometimes used interchangeably.
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.
Safety and airworthiness are sovereign responsibilities. 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. Recognition can be unilateral, bilateral or multilateral.

Timely response is required where airworthiness is affected, which means devising and provisioning rectification action, and promulgating the necessary information to restore safety levels. Recognition, therefore, does not transfer any legal responsibilities from the TAA to the recognized AA. When granting recognition, the TAA will specify any associated terms or condition. The process by which the TAA will undertake this recognition could include: For each of its aircraft, the approved CAMO is required to carry out the following functions.
Terms, conditions and sustainment requirements are normally articulated in a recognition certificate and the supporting documentation. TAM Part 1, Chapter 4 — Assignment of Technical Airworthiness Authority describes the rules and standards for determining the acceptability of organizations that airworthinness been assigned airworthiness management roles or airworthiness functions by a regulatory authority other than the TAA.
Although the owner bears the legal responsibility for continuing airworthiness, there is very much a shared responsibility between:. Furthermore, there is no single, aidworthiness recognized organization that sets standards or harmonizes the military airworthiness and aviation requirements of MAAs.
Continuing Airworthiness – SKYbrary Aviation Safety
This also includes acceptance of FAA organizational approvals related to maintenance, design, manufacturing and materiel support services for civil-derived aeronautical products. For the DND Airworrhiness and the Technical Airworthiness Program, airworthinss relates to airworthiness certification, production oversight and airworthiness inspection continuing airworthiness. 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.
In the words of ICAO:. Reference should also be made to M.
For manuwl, 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. While MAAs may closely align with many of the international civilian airworthiness processes, by necessity, military aviation has a different risk context and will employ military design standards.
As stated in para 4. The process used by the TAA for establishing acceptability of the work and artefacts of another airworthiness regulatory authority is called recognition. Cranfield University Publication Authority: The recognition process follows four basic phases:. This also includes acceptance of TCCA organizational approvals related to maintenance, design, manufacturing and materiel support services for civil-derived aeronautical products; and U.
The four sub-sections are:. The report provides an overall assessment of acceptability and identifies any areas that require clarification through an onsite review.
