Hi Rick,
To carry out the FAR 91 checks, the requirements are, Part 43 Appendix E, has to be carried out by an FAA Approved Repair Facility, not just an A&P.
Apparently, the FAA has basically washed its hands of carrying out audits of the foreign approved FAA Stations and left it with the State Authority to oversee, which is for us is EASA

, therefore the EASA Approved 145 facility needs to have the aircraft on their scope and also be an FAA Approved Repair Station to certify the Avionic inspections on our US machines. Stupid thing is, if this is being covered by EASA, the FAR91 checks aren't applicable, as this is an FAA requirement not EASA.
Before, all it was, was, Approved FAA Repair Facility on a US registered Machine, So easy, but no, they have to change things around
Keepitup
(I will stand corrected on any of the above, and I hope I am !!!!)
