PART 21 - INITIAL AIRWORTHINESS (ANNEX I)

(e) if appropriate, continuation training;
(f) experience;
(g) scope of the authorisation;
(h) date of first issue of the authorisation;
(i) if applicable, the expiry date of the authorisation;
(j) identification (number) of the authorisation;
(j) identification (number) of the authorisation;
(k) documented acceptance of the nomination.
The above information is deemed to be sufficient to provide the CS with evidence of their scope of
authorisation.
The record of this data may be kept in any format. Each CS member should be given reasonable
access on request to his or her own records.
The organisation should keep these records for at least 2 years after the CS member has ceased to
be employed by the organisation, or 2 years after the withdrawal of their authorisation, whichever
occurs first.
21.A.145(d)(3) AMC Approval requirements – Evidence of authorisation
1. The authorisation document must be in a style that makes its scope clear to the certifying
staff and any authorised person who may require to examine the authorisation. Where
codes are used to define scope, an interpretation document should be readily available.
2. Certifying staff are not required to carry the authorisation document at all times but should
be able to make it available within a reasonable time of a request from an authorised
person. Authorised persons include the CAA.
21.A.145(d)(3) AMC1-ELA Approval requirements – Evidence of authorisation
Evidence of the scope of the authorisation may be provided in a reasonably accessible way within the
company, so that a staff member that needs to be aware of the authorisation can verify their status
whenever needed. This can be achieved by the provision of accessible listings of the nominated CS
members, or by other means. The issuing of individual badges or passes is not required.
21.A.147 Changes to the approved production organisation
(a) After the issue of a production organisation approval, each change to the approved
production organisation that is significant to the showing of conformity or to the
airworthiness and environmental characteristics of the product, part or appliance,
particularly changes to the quality system, shall be approved by the CAA. An application
for approval shall be submitted in writing to the CAA and the organisation shall
demonstrate to the CAA, before implementing the change, that it complies with this
Subpart.
(b) The CAA shall establish the conditions under which a production organisation approved
under this Subpart may operate during such changes unless the CAA determines that the
approval should be suspended.
21.A.147 GM1-ELA Changes to the approved production organisation
The company should consider whether to verify the classification of changes with the CAA.
The following changes are considered to be significant and require approval by the CAA prior to the
implementation of the changes:
1. significant changes to the production capacity or methods;
2. changes in the structure of the organisation, especially those parts of the organisation that
are in charge of quality;
3. a change of the accountable manager (AM) or of any other person nominated under point
21.A.145(c)(2);
4. changes in the production or quality systems that may have an important impact on the
conformity/airworthiness of each product, part or appliance;
5. changes in the placement or control of significant subcontracted work or supplied parts;
6. relocation of the major place of activities to a different geographic location, city, airfield or
similar;
7. changes in the scope of approval; and
8. changes in ownership.
21.A.147(a) GM Changes to the approved production organisation – Significant changes
1. Changes to be approved by the CAA include:
- Significant changes to production capacity or methods.
- Changes in the organisation structure especially those parts of the organisation in
charge of quality.
- A change of the accountable manager or of any other person nominated under
21.A.145(c)(2).
- Changes in the production or quality systems that may have an important impact on
the conformity/airworthiness of each product, part or appliance.
- Changes in the placement or control of significant subcontracted work or supplied
parts.
2. To ensure that changes do not result in non-compliance with Part 21 Section A Subpart G
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 (ref 21.A.143(a)(9)).
3. 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
March 2022 128 of 260
