Federal Aviation Administration, DOT.
Notice of proposed rulemaking (NPRM).
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Airbus Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes; and Model A310 series airplanes. This proposal would require revising the Airplane Flight Manual (AFM) to provide the flight crew with procedures to maintain controllability of the airplane in the event of an in-flight deployment of the thrust reverser. The action specified in this AD is intended to ensure that the flight crew is advised of the potential hazard associated with an in-flight deployment of the thrust reverser, and the procedures necessary to address it. This action is intended to address the identified unsafe condition.
Comments must be received by September 9, 2002.

Availability of NPRMs
Any person may obtain a copy of this NPRM by submitting a request to the Start Printed Page 51788FAA, Transport Airplane Directorate, ANM-114, Attention: Rules Docket No. 2001-NM-303-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 all Airbus Model A310 series airplanes, and Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes. The DGAC advises that using the existing thrust reverser “ENG REV UNLK” procedures in the Procedures Following Failures section of the Airplane Flight Manual (AFM) could result in reduced controllability of the airplane in the event of an in-flight deployment of the thrust reverser.
Explanation of Relevant French Airworthiness Information
The DGAC issued French airworthiness directive 2001-186(B) dated May 16, 2001, in order to assure the continued airworthiness of these airplanes in France. The French airworthiness directive requires incorporating certain AFM revision pages into the AFM of the subject airplane models.
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 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 designs registered in the United States, the proposed AD would require revising the Limitations and Procedures sections of the AFM. The procedure defines actions to be taken by the flight crew in case of an uncommanded in-flight deployment of the thrust reverser.
Differences Between the French Airworthiness Directive and Proposed Rule
The French airworthiness directive requires revising the AFM in accord with certain AFM revisions. This proposed AD would require that the procedures described in those certain AFM revisions be incorporated into the AFM in accord with this proposed AD.
The FAA estimates that 128 airplanes of U.S. registry would be affected by this proposed AD, that it would take approximately 1 work hour per airplane to accomplish the proposed AFM revision, and that the average labor rate is $60 per work hour. Based on these figures, the cost impact of the proposed AD on U.S. operators is estimated to be $7,680, or $60 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 proposed 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 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 2001-NM-303-AD.
Applicability: All Model A310 series airplanes, and all Model A300 B4-600, A300 B4-600R, and F4-600R (collectively called A300-600) series airplanes; certificated in any category.
Compliance: Required as indicated, unless accomplished previously.
To prevent reduced controllability of the airplane in the event of an in-flight deployment of the thrust reverser, accomplish the following:
Revisions to the Airplane Flight Manual
(a) Within 60 days after the effective date of this AD, revise the Procedures Following Failures section of the Airplane Flight Manual (AFM) to include the “ENG REV UNLK” procedure contained in this paragraph of this AD. This may be accomplished by inserting a copy of this AD into the AFM.

Alternative Methods of Compliance
(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116.
Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Manager, International Branch, ANM-116.
Special Flight Permits
(c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished.
The subject of this AD is addressed in French airworthiness directive 2001-186(B), dated May 16, 2001.
Issued in Renton, Washington, on July 29, 2002.
