GM1 21.A.147 Changes to the approved production organisation

CAA ORS9 Decision No. 40

CHANGES IN THE PRODUCTION MANAGEMENT SYSTEM - SIGNIFICANT CHANGES

Changes to be approved by the CAA include:

— significant changes to the production capacity or methods;

— changes in the organisation’s structure, especially those parts of the organisation in charge of the safety management element or the quality management element of the organisation’s production management system;

— a change of the accountable manager or of any other person that is nominated under point 21.A.145(c)(2) and (4);

— changes in the production management system that may have an important impact on the conformity or airworthiness of any product, part, or appliance, including in the reporting lines between the personnel that are nominated in accordance with point 21.A.145(c)(2) and (4) and the accountable manager; and

— changes in the placement or control of significant subcontracted work or supplied parts.

To ensure that changes do not result in non-compliance with Part 21, it is in the interest of both the CAA and the approval holder to establish a relationship and exchange information that will permit the necessary evaluation work to be conducted before the implementation of a change. This relationship should also permit agreement on the need for variation of the terms of approval (refer to point 21.A.143(a)(9)).

Where a change of name or ownership results in the issue of a new approval, the investigation will normally take account of the CAA’s knowledge and information from the preceding approval.

Changes of location are addressed in point 21.A.148, changes of ownership in point 21.A.149, and the change of scope of the approval in point 21.A.153.
