If you can't achieve a additional FORM ONE (sometimes the certificates are possible, but only on request), then the FAA 8130-3 needs a dual release. In field 19 (18) the point: "Other Regulation specified in block 13 (12) " must be marked and in field 13 (12) of the Form.
In Field 13 (12) the wording: " “[Name of repair station] certifies that the work specified in Blocks 12 and 13 was performed in accordance with EASA part 145 approval and with respect to that work, the aircraft component is considered ready for release to service under EASA approval number [insert number].”
In both cases need the MRO/MAN also a EASA-Rating.
This also works the other way round, so a FORM ONE-part can be installed on N-Reg. A/C with a dual release and a FAA remark in Field 12(13).
