21.A.133 Eligibility

‘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 competent authority considers a POA inappropriate)

2.Production of ETSO articles and parts marked EPA

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

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

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

6.Where an approval is otherwise determined by the competent authority 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 competent authority 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.)
