Dick,
Maybe its about time you got out more often - no disrespect but look
here.
And if you follow your nose you will find the requirements are in the Instructions for Continuing Airworthiness
(read Maintenance Manual, Service Bulletins) as part of the issue of a Type Certificate.
As to why Australia promulgated an AD, who knows maybe it was to cover older aircraft without an adequate maintenance manual?
Maybe it was the only method available at the time.
But then again CASA is hell bent on living in the dark ages by the looks. They still re-issue manufacturers AD's FFS! What a waste of time.
Every other NAA has woken up and uses the AD's issued by the state of manufacture which these days are readily available.
Non specific and General AD's notwithstanding of course.
How's about you just bung a ZK on the tail and life would be so much easier because you can!!
AUS Needs to get over itself and its so-called uniqueness and has been drinking its own Koolaid for far too long.
Its called Globalisation ya know. Lets not get onto the cluster called Part 61!
