Man your guys shopping list just gets longer every time I log in.
What machine are you looking at?
From what I can remember what you are looking at is the aircraft registaration which is a flight manual requirement which lists the legal owner of the aircraft.(someone who as legal right to the machine for more than 30 days)
The airworthyness cirtificate is another flight manual document that deals with the scedualed maintainance of the aircraft. You will probobly have to get anouther annual inspection done and insure you are current with all airworthy directives before being issued with a new certificate. However your maintainace that is cycle/hours dependant should be still on hold(I think, we are talkin 5 years).
The place you really want to spent some time at is The NZ CAA website(im sure it was designed by the same company that did the tax departments
).
http://www.caa.govt.nz/index.htmlThe Law is in the Civil aviation act 1990 also on the website relevent parts are;
Part 39 Airworthiness Directives
http://www.caa.govt.nz/rules/Part_039_Brief.htmPart 43 General Maintenance Rules
http://www.caa.govt.nz/rules/Part_043_Brief.htmPart 47 Aircraft Registration and Marking
http://www.caa.govt.nz/rules/Part_047_Brief.htmA bit of homework I know but it is all there in black and white. Please do not take what I have said as gospel it was just were I would start off the top of my head. I hope it helps. Feel free to pm me or post if you guys have any questions.
Fly safe
