Requirement:

Action in accordance with the requirements of EASA AD 2007-0133.

Note:  Airbus A330 ALS Part 1, Revision 01 approved 30 March 2007, or later EASA approved revision, refers.

Compliance:

From the effective date of this Directive.

This Amendment becomes effective on 5 July 2007.

Background:

Airbus A330 aircraft life limited parts have been transferred from Aircraft Maintenance Manual Chapter 05 to the Life Limits/Monitored Parts Section 9-1 of Airworthiness Limitations Section 9 of the MPD.  Airbus issued A330 MPD sub-sections 9-1-2 and 9-1-3 at Revision 01 to introduce some new life-limited parts and to change the values of some limits (original limit decrease and/or incorporation of flight hour limitations).

Amendment 1 introduced Revision 03 of Airbus A330 MPD subsection 9-1, which was issued to change the values of some limits already listed (original limit decrease and/or incorporation of a Flight Hours limitation).

Amendment 2 introduced Revision 04 of A330 MPD subsection 9-1 to include Models A330-302 and A330-303 aircraft, and to increase life limitations values for “Growth” Landing Gear parts; while the values of some limitations already listed were decreased.

Amendment 3 introduced Revision 05 of Airbus A330 MPD subsection 9-1 which was issued to introduce the A330-202 and A330-302 weight variant 53, and to introduce new part numbers for some items already listed.  However, the values of some limitations already listed were decreased.

Amendment 4 introduced the transfer of the list of Safe Life Airworthiness Limitations Items (SL ALI) into the Airworthiness Limitations Section (ALS), and the limitations applicable to SL ALI are now listed in the ALS Part 1, which is approved by EASA.

Amendment 5 is issued in response to a new EASA AD, which was prompted by Revision 01 of Airbus A330 ALS Part 1 which was issued to introduce the A330-201, -202, -203, -223 weight variant 023; and the A330-201, -202, -203, -223, -243 weight variant 056.  Further, the values of some limitations assigned to items already listed were reduced and the list of the wing structure SL ALI part numbers has been amended.  Furthermore Revision 01 of the A330 Part 1 is addressing the life limit  requirements on the MLG retraction link, mandated earlier by EASA Emergency AD 2006-0324-E (AD/A330/65), which is superseded by this Directive.
