Compliance: If a certificate of airworthiness has not been issued for the aircraft - before issue of the certificate of airworthiness.

Background: The FAA ADs listed in Table 1 of this Directive require once-only actions for which the compliance date and/or period has passed. CASA has determined that these ADs may be applicable to Australian registered aircraft. This Directive is issued to ensure all State of Design ADs are complied with. CASA appreciates that, due to date of aircraft manufacture or aircraft configuration and modification status, some of the ADs listed in Table 1 will not be applicable to some aeroplanes.
