If a certificate of airworthiness has been issued for the aircraft - before further flight after 60 days from the effective date of this Directive. This Airworthiness Directive becomes effective on 27 August 2010. Background: The SADs listed in Table 1 of this Airworthiness Directive require once-only actions for which the compliance date has passed. CASA has determined that these SADs may be applicable to some Australian aircraft. This Airworthiness Directive is issued to ensure compliance with all State of Design ADs. CASA appreciates that, due to date of aircraft manufacture or aircraft configuration and modification status, some of the SADs listed in Table 1 will not be applicable to any aircraft presently registered in Australia.
