Hi Flingwing 1
Don't expect a reply back from PACA any time soon, they are notoriously un-communicative, and their website........... doesn't really meet todays expectation of a regulator. PACA regulations follow EU Ops quite closely, and the last issue of manuals was in 20011/12. For Flight ops they issued CAR-OPS and CAR-FCL, for maintenance they have issued CAR-M and CAR 145,..... and thats it.
What is your interest in Oman, I may be able to help as I am currently in country on project.
