Federal Aviation Administration, DOT.
Notice of proposed rulemaking (NPRM).
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.

Availability of NPRMs
Any person may obtain a copy of this NPRM by submitting a request to the FAA, Transport Airplane Directorate, ANM-114, Attention: Rules Docket No. 2002-NM-18-AD, 1601 Lind Avenue, SW., Renton, Washington 98055-4056.
The Direction Générale 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.
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 Start Printed Page 70214certificated 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.
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.
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.Start List of Subjects

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:Start Part
PART 39—AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
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:
(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.
The subject of this AD is addressed in French airworthiness directive 2001-634(B), dated December 26, 2001.
Issued in Renton, Washington, on December 5, 2003.
