Airworthiness Directive · Amendment 39-17408 · Equipment/furnishings
Airbus Airplanes
This AD applies to Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-111, -211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes; certificated in any category; all manufacturer serial numbers.
We are superseding an existing airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. That AD currently requires installing spacer assemblies at the attachment points of the YZ-latches of the cargo loading system (CLS) in the forward and aft cargo compartments, as applicable. This new AD also requires modifying the attachment points of fixed YZ-latches of the CLS lower deck cargo holds on those airplanes on which one or both lower deck cargo holds have not been modified, which terminates the existing requirements. This AD was prompted by results from tests that have shown that the attachment points of the YZ-latches of the cargo loading system (CLS) fail under maximum loads and reports that installation has been applied only on one of the lower deck cargo holds, instead of on both forward and aft cargo holds, and that some airplanes could have installed the affected YZ-latches through the instructions of the cargo conversion manual. We are issuing this AD to prevent failure of the attachment points of the YZ-latches, which could result in unrestrained cargo causing damage to the fire protection system, hydraulic system, electrical wiring, or other equipment located in the forward and aft cargo compartments. This damage could adversely affect the continued safe flight of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
This paragraph restates the requirements of paragraph (f) of AD 2007-05-13, Amendment 39-14974 (72 FR 10348, March 8, 2007). For Airbus Model A319, A320, and A321 series airplanes identified in paragraphs (g)(1) and (g)(2) of this AD: Within 36 months after April 12, 2007 (the effective date of AD 2007-05-13), install spacer assemblies at the attachment points of the YZ-latches of the CLS in the forward and aft cargo compartments, as applicable, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-25-1294, Revision 02, dated September 5, 2006. Accomplishing the actions in paragraph (h) of this AD terminates the requirements of paragraph (g) of this AD.
(1) Airplanes on which one of the following has been incorporated in production: Airbus Modification 20065, 20040, 24495, 24848, 24496, 21895, 21896, 25905, 25907, 22601, 22602, 27187, 28319, 28322, 28330, 28335, or 31797.
(2) Airplanes on which one of the following has been incorporated in service: Airbus Service Bulletin A320-25-1132, A320-25-1133, A320-25-1145, A320-25-1175, A320-25-1177, A320-25-1276, A320-25-1278, A320-28-1134, or A320-28-1141.
Except for Model A319, A320, and A321 series airplanes on which both Airbus Modifications 32244 and 32245, or both Airbus Modifications 32316 and 32317, have been incorporated in production, and on which no YZ-latch replacements have been made since first flight: Within 20 months after the effective date of this AD, modify the attachment points of fixed YZ-latches of the CLS, having a part number (P/N) listed in paragraphs (h)(1) through (h)(7) of this AD, in both forward and aft lower deck cargo holds by adding spacer assemblies having P/N D2557232700000, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A320-25-1294, Revision 06, dated July 23, 2010. Accomplishing the actions specified in paragraph (h) of this AD terminates the requirements of paragraph (g) of this AD.
(1) P/N D 255 7 2380 000.
(2) P/N D 255 7 2380 002.
(3) P/N D 255 7 2380 006.
(4) P/N D 255 7 2380 008.

(7) P/N D 255 7 2350 006.
As of the effective date of this AD, no person may install, on the CLS of any airplane, a YZ-latch having a part number listed in paragraphs (h)(1) through paragraph (h)(7) of this AD, unless it has been modified in accordance with the requirements of paragraph (h) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
