GM 21.A.133(a) Eligibility – Approval appropriate for showing conformity    

CAA ORS9 Decision No. 1

‘Appropriate’ should be understood as follows:

— The applicant produces or intends to produce aeronautical products, parts and/or appliances intended for airborne use as part of a type-certificated product (this excludes simulators, ground equipment and tools).

— The applicant will be required to show a need for an approval, normally based on one or more of the following criteria:

1. Production of aircraft, engines or propellers (except if the CAA considers a POA inappropriate)

2. Production of UKTSO articles and parts marked UKPA

3. Direct delivery to users such as owners or operators maintenance organisations with the need for exercising the privileges of issuing Authorised Release Certificates – CAA Form 1

4. Participation in an international co-operation program where working under an approval is considered necessary by the CAA

5. Criticality and technology involved in the part or appliance being manufactured. Approval in this case may be found by the CAA as the best tool to exercise its duty in relation to airworthiness control

6. Where an approval is otherwise determined by the CAA as being required  to  satisfy  the  essential  requirements  of  Annex I  to  the  Regulation (EC) No 216/2008.

— It is not the intent of the CAA to issue approvals to manufacturing firms that perform only sub-contract work for main manufacturers of products and are consequently placed under their direct surveillance.

— Where standard parts, materials, processes or services are included in the applicable design data (see guidance on applicable design data in GM 21.A.131) their standards should be controlled by the POA holder in a manner which is satisfactory for the final use of the item on the product, part or appliance. Accordingly, the manufacturer or provider of the following will not at present be considered for production organisation approval:

— consumable materials

— raw materials

— standard parts

— parts identified in the product support documentation as  ‘industry  supply’  or ‘no hazard’

— non-destructive testing or inspection

— processes (heat treatment, surface finishing, shot peening, etc.)
