However, the position has now been placed beyond all doubt. First, the Civil Aviation
Legislation Amendment (Airworthiness and Other Matters-2015 Measures No. 1)
Regulation 2015 amended Schedule 5 of CAR 1988 to omit the previous mention of
maintenance within the limits specified in CAO 108.34 and direct the required
maintenance to be carried out in accordance with the approved maintenance data for the
system.
:- Now if approved data needs to be used and CAsA don't supply "data" in schedule 5 then you need data from another source the fist is the airframe manufacturer (unless modified by a EO) and if they don't supply it then the component manufacturer.
You must follow all this data including inspection limits if applicable or you are not carrying out IAW that approved data.
