Note:  EASA and DGAC ADs may be accessed via the internet at the following URLs:
Compliance:	For Requirements 1 and 2 - Within 30 days after the effective date of this Directive or prior to the issue of a Certificate of Airworthiness, whichever occurs first.
This Airworthiness Directive becomes effective on 22 June 2007.
Background:	The DGAC and EASA ADs listed in Table 1 and 2 of this Directive require one time actions for which the compliance date and/or period has passed.  CASA has determined that these ADs may be applicable to recently registered or imported 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, not all the ADs listed in Table 1 and 2 will be applicable to all ATR 42 series aeroplanes.
