I think you'll find that getting an AOC is a little more involved than just filling a form in. The way the CAA works is that you tell them you want something like this and you enter a period of discussion and piles of paperwork (submitted from you!) until they're happy. Then a miracle happens - at least I assume that's what it must be because of the time it takes and the money it costs - and then you get your AOC.
PS - this is based on getting approval for an ILS but I think the same principles apply!
