AMC 21.B.120 Evaluation of applications

CAA ORS9 Decision No. 1

1. General

When applying Part 21 Section A Subpart F and Section B Subpart F the CAA must consider that these Subparts are only an alternative way for production to Part 21 Section A Subpart G and Section B Subpart G. To meet the ICAO airworthiness obligations and to issue a Certificate of Airworthiness for an individual aircraft in a practical and efficient way, the CAA must use a system of approval of production organisations (POA) under Part 21 Section A Subpart G and Section B Subpart G, providing to the CAA the necessary confidence in technical standards. The consistent standards of these approvals will also support the standardisation efforts by the CAA. Nevertheless it is recognised that it is not always practical, economical and/or advisable to use the POA.

Considering ICAO airworthiness obligations as well, Part 21 Section A Subpart F and Section B Subpart F is provided for such a case on the basis of the following principles:

a) Subpart F must be considered as an alternative option for particular cases

b) Its adoption must be done on an individual basis, as consequence of an assessment by the CAA (see 21.A.121, 21.A.133(a) and their associated CS and GM).

2. Application

The CAA must receive an  application  for  a  letter  of  agreement  on  a CAA Form 60 (see below) completed by the applicant. The eligibility of the application should be verified in relation to the CAA procedures, based on 21.A.121 and its associated CS and GM. The applicant should be advised accordingly about the acceptance or rejection of the application.

3. Location of the applicant

The location of the applicant seeking acceptance for production under Part 21 Section A Subpart F determines which CAA is responsible for issuing the letter of agreement.
