377 # 238 –"The expositions are an overkill in Australia".
When the NZ regs are brought in, many a CP will be a happy chappy (or chapess). You start with your 500 pages, two red pencils and a coffee, then get to it. Within a pleasant sort of days work identify the bits that you want to keep and biff the rest, most satisfactory.
Start with the very practical 70 pages of part 61, pick the bits which affect you, dream up a method which suits your company systems and requirements and off you go. Even with indexing, document control and a bit of fluff on the side, a part 135 "exposition" will only run to a nicely spaced 100 pages; don't want 135 operations OK with careful management your part 125 (QA/SMS/Security manual excluded) will only run you out to perhaps 120 similar pages.
You do need to know your stuff though, the NZ rules are 'tight', devilish cunning, outcome based and delve into realms real operational expertise, rather than the subjective prescriptive. Should be able to adapt a lot of the old stuff directly, and if you're silly enough to want to quote a "rule number" then you need to pay a bit more attention.
Having ploughed through some of the anally retentive, agonised quasi legal mine fields that are laughingly referred to as "Operations Manuals" in Australia, I should imagine the average CP would be glad to spend a happy week or ten days crafting a manual which may be used for more than keeping the door open on a warm day.
