If CASA got out of the business of approving checklists maybe the local industry could follow world's best practice and move in this direction.
Particularly when the "CASA approved" check list is contrary to the aircraft's AFM.
Remember the Jetstar A320 missed approach in Melbourne.
The AFM, with which compliance is legally required. See CASR Part 21 and CAR 138, where "flight manual" means the AFM, part of the aircraft certification package.
I constantly marvel at the CASA ability to not understand the ramifications of their own legislation.
CASA have no power to direct amendment to an AFM, unless it is an Australian type certified aircraft ---- which excludes all but a handful of the aircraft on the Australian Civil Register.
