Applicability:

A319, A320 and A321 series aeroplanes manufactured prior to 1 January 2002.

Requirement:

  1. Determine the applicability of the French Directorate General for Civil Aviation (DGAC) and United States of America Federal Aviation Administration (FAA) Airworthiness Directives (AD) listed in Table 1, as in force from time to time.

Note 1: The words “as in force from time to time” require compliance with the most recent version of the referenced document.

2. If it is determined that an AD listed in Table 1 is applicable and has not been previously accomplished, perform the actions required by that AD.

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 - within 30 days after the effective date of this Directive.

Note 2: Previous compliance with the requirements of DGAC AD 1996-293(B)R1 as required by CASA AD/APU/22, AD/A320/199 or AD/A320/199 Amdt 1, constitutes compliance with FAA AD 97-03-06 as required by this amendment.

This Airworthiness Directive commences on 31 March 2021.

Background:

The 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 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.The original issue of this Directive applied only to A319 aeroplanes and became effective on 15 March 2007.

Amendment 1, extended the applicability to include A320 and A321 aeroplanes, amended the title of the AD, restricted applicability to aeroplanes manufactured prior to 1 January 2002, and incorporated an additional eight State of Design ADs.

Amendment 2 of this Directive removes obsolete website information and replaces DGAC AD 1996-293(B)R1 with FAA AD 97-03-06 because the FAA is the State of Design for the applicable equipment, and the FAA AD addresses the same unsafe condition.
