If a certificate of airworthiness has been issued for the aircraft - within 60 days after the effective date of this Directive. This Airworthiness Directive becomes effective on 7 July 2010. Background: The Netherlands 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 recently-registered Australian 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.
