Airworthiness Directives; Airbus Model A319, A320, and A321 
Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This document proposes the adoption of a new airworthiness 
directive (AD) that is applicable to certain Airbus Model A319, A320, 
and A321 series airplanes. This proposal would require replacing the 
upper guide rod fittings at the rear passenger doors with improved 
fittings. This action is necessary to prevent failure of an upper guide 
rod fitting, which could cause a rear passenger door to jam during 
opening, delaying an emergency evacuation and resulting in injury to 
passengers or crew members. This action is intended to address the 
identified unsafe condition.

DATES: Comments must be received by January 16, 2004.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, ANM-114, 
Attention: Rules Docket No. 2002-NM-18-AD, 1601 Lind Avenue, SW., 
Renton, Washington 98055-4056. Comments may be inspected at this 
location between 9 a.m. and 3 p.m., Monday through Friday, except 
Federal holidays. Comments may be submitted via fax to (425) 227-1232. 
Comments may also be sent via the Internet using the following address:

98055-4056.

Discussion

    The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), 
which is the airworthiness authority for France, notified the FAA that 
an unsafe condition may exist on certain Airbus Model A319, A320, and 
A321 series airplanes. The DGAC advises that there have been several 
reports of cracking and rupture of the upper guide rod fittings for the 
rear passenger doors on in-service airplanes. This condition, if not 
corrected, could cause a rear passenger door to jam during opening, 
delaying an emergency evacuation and resulting in injury to passengers 
or crew members.

Explanation of Relevant Service Information

    Airbus has issued Service Bulletin A320-53-1154, Revision 2, dated 
March 7, 2003. That service bulletin describes procedures for replacing 
the upper guide rod fitting on each rear passenger door with an 
improved fitting. The improved fitting is stronger than the existing 
one due to an increase in thickness and different material.
    Accomplishment of the actions specified in the service bulletin is 
intended to adequately address the identified unsafe condition. The 
DGAC classified a previous revision of this service bulletin as 
mandatory and issued French airworthiness directive 2001-634(B), dated 
December 26, 2001, to ensure the continued airworthiness of these 
airplanes in France.

FAA's Conclusions

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. The FAA has examined the findings of 
the DGAC, reviewed all available information, and determined that AD 
action is necessary for products of this type design that are

[[Page 70214]]

certificated for operation in the United States.

Explanation of Requirements of Proposed Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other airplanes of the same type design registered 
in the United States, the proposed AD would require accomplishment of 
the actions specified in the service bulletin described previously.

Cost Impact

    The FAA estimates that 440 airplanes of U.S. registry would be 
affected by this proposed AD, that it would take approximately 10 work 
hours per airplane to accomplish the proposed actions, and that the 
average labor rate is $65 per work hour. Required parts would cost 
approximately $2,200 per airplane. Based on these figures, the cost 
impact of the proposed AD on U.S. operators is estimated to be 
$1,254,000, or $2,850 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the proposed requirements of 
this AD action, and that no operator would accomplish those actions in 
the future if this AD were not adopted. The cost impact figures 
discussed in AD rulemaking actions represent only the time necessary to 
perform the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions. The manufacturer may cover the cost of 
replacement parts associated with this proposed AD, subject to warranty 
conditions. As a result, the costs attributable to the proposed AD may 
be less than stated above.

Regulatory Impact

    The regulations proposed herein would not have a substantial direct 
effect on the States, on the relationship between the national 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Therefore, it 
is determined that this proposal would not have federalism implications 
under Executive Order 13132.
    For the reasons discussed above, I certify that this proposed 
regulation: (1) Is not a ``significant regulatory action'' under 
Executive Order 12866; (2) is not a ``significant rule'' under the DOT 
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 
and (3) if promulgated, will not have a significant economic impact, 
positive or negative, on a substantial number of small entities under 
the criteria of the Regulatory Flexibility Act. A copy of the draft 
regulatory evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of the Federal Aviation Regulations (14 CFR part 39) as 
follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:

Airbus: Docket 2002-NM-18-AD.

    Applicability: Model A319, A320, and A321 series airplanes; 
certificated in any category; on which Airbus Modification 30821 has 
not been accomplished.
    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent failure of an upper guide rod fitting, which could 
cause a rear passenger door to jam during opening, delaying an 
emergency evacuation and resulting in injury to passengers or crew 
members, accomplish the following:

Replacement

    (a) Within 22 months after the effective date of this AD, 
replace the upper guide rod fitting on each rear passenger door with 
an improved fitting by doing all actions in and per the 
Accomplishment Instructions of Airbus Service Bulletin A320-53-1154, 
Revision 2, dated March 7, 2003.

Replacements Accomplished Previously

    (b) Replacements accomplished before the effective date of this 
AD per the Accomplishment Instructions of Airbus Service Bulletin 
A320-53-1154, dated July 12, 2001; or Revision 1, dated August 28, 
2002; are acceptable for compliance with the corresponding action 
required by this AD.

Alternative Methods of Compliance

    (c) In accordance with 14 CFR 39.19, the Manager, International 
Branch, ANM-116, Transport Airplane Directorate, FAA, is authorized 
to approve alternative methods of compliance for this AD.

    Note 1: The subject of this AD is addressed in French 
airworthiness directive 2001-634(B), dated December 26, 2001.
