FAQ n.123570

As a UK-based production organisation, how do I mark a part/appliance produced in accordance with EASA approved design data?

Answer

As per 21.A.804, the “EPA” marking should be used for parts or appliances produced in accordance with approved design data not belonging to the type-certificate holder of the related product, except for ETSO articles.

Part/appliance manufactured in accordance with EASA design data (approved either through an EASA-issued certificate or through an approval by an EASA DOA, including approval prior to January 01, 2021 from a now UK DOA working under the regime of an EASA DOA at that time) should be marked as “EPA”.

As a UK-based production organisation, such parts should be marked with “EPA” and released with a UK CAA Form-1.
