Note:   TCA ADs may be accessed via the internet at the following URL:

            

Compliance:

For Requirements 1 and 2 - Remains unchanged from the initial Airworthiness Directive, as within 30 days after the effective date of this Directive or prior to the issue of a Certificate of Airworthiness, whichever occurs later.

This Amendment becomes effective on 14 November 2011.

Background:

The TCA ADs listed in Table 1 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 will be applicable to all Regional Jet series aeroplanes.

Amendment 1 was issued to remove Airworthiness Directive (AD)
CF-2003-23R2 as this AD has been superseded by CF-2003-23R3 which is a State of Design AD.

Amendment 2 has been issued to remove Airworthiness Directive (AD)
CF-2002-41 from the list in table 1 as this AD has been superseded by AD
CF-2011-39 which is a State of Design AD.
