To be clear, strictly speaking in most cases based on bilateral agreement, FAA certifies US products and EASA validates the FAA certification as having found compliance with EASA CS25 and then EASA issues a Type Certificate. There are variations for aspects which EASA chooses to retain compliance finding, and there can be many meetings between authorities to resolve certification issues. It would not surprise me at all, that all that EASA and the certification authorities of non-EU countries will opt to retain compliance finding for the "fix." Wouldn't surprise me if the authorities meeting on May 23, hosted by FAA, has this very point on the agenda.
