Note 1: FAA ADs may be accessed via the internet at the following URL:
Compliance:	If a certificate of airworthiness has not been issued for the aircraft - before issue of the certificate of airworthiness. 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 30 July 2010.
Background:	The FAA ADs listed in Table 1 of this Directive require once-only actions for which the compliance date has passed.  CASA has determined that these ADs may be applicable to some Australian aircraft.  This 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 ADs listed in Table 1 will not be applicable to any aircraft presently registered in Australia.
