In that case, you are correct: There is an automatic obligation to comply with what the CASRs call a ‘foreign State of Design airworthiness directive’ (as well as comply with an ‘Australian airworthiness directive’). That’s because CASR 39.002 imposes an obligation to comply ‘airworthiness directives’, and the definition of ‘airworthiness directive’ in CASR 39.001A covers both ‘Australian airworthiness directives’ and ‘foreign State of Design airworthiness directives’.
I merely reiterate that CASA has the discretion to approve a means of compliance with an AD other than that set out in the AD, and CASA has the discretion to exclude a particular kind of aircraft or aeronautical product from the operation of an AD: see CASRs 39.004(2) and 39.004(3).

The approved maintenance
data for an aircraft and the maintenance
schedule applicable an aircraft are related but different regulatory concepts. Read all about them here:
