Is every PMA part has to have an 8130 form?
Or compliance with part 21.303 is all you need?
Thanks in advance.

Does anyone have this information?

All PMA (Part Manafacture Approval) parts that are exported that are for instalation on comercial aircraft have to have this tag.
For domestic if they are going to an OEM they are not needed if the customer does not request them.
Most of the time they are always requested if they are needed or not.
If you are the sub to the holder of a PMA you can not place the 8130-3 on the part as you do not have the actual PMA approval.
Follow Order 8130.21 for proper use.

Are you referring to FAA form 8130-3?

It depends on what you are doing with the PMA part as the 8130-3 tag has multiple uses. If you are exporting the part to a country that we (USA) have a bilateral agreement with and the part is new and your customer is requesting an 8130-3 tag, then the answer is most likely “maybe”. The tag can also be used by a certified repairman for returning a product to service.

The following order explains the usage for the 8130-3 tag.
