Are the repairs / alterations / changes, that are validated under the FAA PART 26 rule, automatically acceptable under the new EASA AASR rule?

Are the REG's for example on a Boeing model (that meets the FAA ASSR / PART 26 requirements) accepted by EASA? If so, automatically? Do the TCH's individually have to apply for the review and approval of the REG?

Point 26.331: Shall a compliance plan be submitted to EASA by STC holders that do not hold structures in their DOA Scope of Work; and only owns STCs that are cabin related and do not introduce fatigue-critical modified structure (FCMS)?

As STC Holders how can we obtain the list of FCBS?

When not sure if FCBS is affected by an STC, is there any Compliance Plan required?

An EASA approved STC is applied to aircraft which are nowadays operated in the US under FAA regulations. Does the F&DT still need to be performed? Or could we wait until an actual operator contacts us?

Will Appendix 1 Table A.1 be updated to list all aircraft who successfully apply for exceptions per 26.300 via their compliance plans?

There are many structural repairs manual (SRM) repairs to fatigue critical structure (FCS) however the SRM does not define the classification of the repair per 21A91/21.435. How does an operator know the repair classification if it has not been specified per SRM?

26.370(a) (ii): where an operator's fleet consists of a/c certificated after 2009 and therefore has no REG - there will be no "REG" survey compliance threshold for repairs. When does one therefore plan to review the DTI?

Will rework repairs (blend out, trim-outs, etc.) be on a list of repairs that require DTE?

Is it our correct interpretation of 26.370 g(5) that a physical survey for repairs for aircraft certified as per CS 25.571 (Damage Tolerance) is not a must as long as repair records for the aircraft are considered complete by the CAMO and the requirements per TC REG are complied with for any known repair?

Who needs to evaluate a change / repair in case the original design organization for the change / repair no longer exists?

Typically a DTI has a threshold and interval, how should the operator establish that start time (to calculate the 1st due inspection) if an unrecorded Mod/repair was found during the survey, and not knowing the cycles/landing at Incorp of the Mod/repair? Is that covered by the Reg?

Regulation (EU) 2021/699 introduced point 21.A.101(h) that refers, among others, to point 26.320 of Regulation (EU) 2015/640 but this point is not present in the said regulation. Could you please clarify?
