No problem, the approved list of repair documents has been removed from the CAR's and is now contained in a temporary instrument found here:
http://www.casa.gov.au/wcmswr/_asset...60/casa515.pdf
presumably this will soon be incorporated into the CASR's as is the current CASA process for developing new rules - remove old rules and the bulk of new ones using instruments (or CAAP) to fill any gaps until all can be incorporated into the new suite.
This take stime and can lead to comfusion with rules and regulations spread amongst CAR, CASR, CAAP and Instruments until it all gets consolidated.
The FAA corrosion repair AC can be found here:
AC 43-4A - [Large AC] Corrosion Control for Aircraft - Document Information
As for using AC 43 in lieu of SRM it depends on what the aircraft manual say. Mine states:
Minor repairs such as patching the fabric, welding, wing rib repair, etc. may be made in accordance with regulations set forth in FAA Advisory Circular 43.13-1( ). No major structural repairs are recommended without consulting the manufacturer.
You will find a similar statement in the structures section of the Maintenance manual for most GA aircraft (Beech are the exception I can think of). And although my aircraft states fabric it is actually a 2002 build so this is not just for old aircraft!
