Selfish,
We have the MA's mentioned, plus more, and as refered to earlier they generally cost about $A250, but with the current doubling of hourly rates for CASA charges, I expect the MA charges will also increase. The fun bit is when the pilot has to show the LAME how to fit a camera mount, so the LAME can then certify the pilot knows what he's doing....

and write to CASA to say so!!!
BT,
Amazed yours was free, but was your company invoiced for the MA? I always get the bills for MA's for my pilots, regardless of how complicated they are. And the LAME's bill for their contribution
Helibiz,
What you are asking is always sensible, but CASA now have as many lawyers as FOIs, or so it seems. Note that the CAAP allows you to carry out fabric repairs, then you'd get an idea how out of date it is.
My only thought is that dual controls are considered part of the flying controls, which are usually required to have a duplicate inspection when disturbed. Following that line of reasoning, CASA and the Airworthiness section would have to jump through hoops to allow it to be incorporated in a type endorsement without somehow bringing a LAME into the equation. How would they seperate the simple (R22 cyclic) from the complicated (Bell 206 pedals)? An incident with pedals fitted incorrectly by a pilot to a 206 about 20 years ago caused much grief at the time, and is probably not forgotten.
With the move toward all Transport Class B and Class A coming under the same system, the Class A method of approvals issued at company level by the Maintenance Controller may/should/will overcome many of these issues, but only with the oversight of Airworthiness Division. Don't forget, they (Airworthiness) are even a referral agent for the issue of AOC's, and are the ratbags responsible for the farcical division of turbine types, such that the Bell 206 now requires about 8-10 different sub classifications

And you can't have a Class A type unless you have a Maintenance System, but you can't have a Maintenance System unless you have the aircraft in the hangar: according to Airworthiness!!!!
The possibility of changing all this is in our hands: what are you doing to make your ideas known to CASA, because this is the only chance you'll get, through the current CASR committees.
