For Part-NCO it is only 3 pages, 133-135: AMC/GM for approach and landing conditions and AMC/GM for Minimum Equipment List (MEL).
JFYI.
ORS9 CAA Decision No15 local copy.
I wonder what this has that’s relevant to GA? There is no summary.
Peter, I found only 3 pages (somewhat) relevant, the rest of it is for CAT,NCC and SPO. All three pages just AMC and GM (not hard law) and it is two paragraphs on MEL (that there should be a procedure) and the rest is about the runway condition reports (RCR).
