Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
One A300-600 aeroplane operator reported that, during a routine inspection, the Right Hand frame 40 forward fitting between stringer 32 and stringer 33 was found cracked. The subject aeroplane had previously been modified in accordance with Airbus SB A300-57-6053 (Airbus Modification 10453).
This condition, if not corrected, could result in a deterioration of the structural integrity of the frame.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
We must receive comments on this proposed AD by December 14, 2009.
You may send comments by any of the following methods:
For service information identified in this proposed AD, contact Airbus SAS—EAW (Airworthiness Office), 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France; telephone +33 5 61 93 36 96; fax +33 5 61 93 44 51; e-mail: account.airworth-eas@airbus.com; Internet http://www.airbus.com. You may review copies of the referenced service information at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington. For information on the availability of this material at the FAA, call 425-227-1221 or 425-227-1152.
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this proposed AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
Dan Rodina, Aerospace Engineer, International Branch, ANM-116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-2125; fax (425) 227-1149.
We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2009-0993; Directorate Identifier 2009-NM-089-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments.
We have lengthened the 30-day comment period for proposed ADs that address MCAI originated by aviation authorities of other countries to provide adequate time for interested parties to submit comments. The comment period for these proposed ADs is now typically 45 days, which is consistent with the comment period for domestic transport ADs.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued Airworthiness Directive 2009-0094, dated April 21, 2009 (Correction: May 29, 2009) (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:
One A300-600 aeroplane operator reported that, during a routine inspection, the Right Hand frame 40 forward fitting between stringer 32 and stringer 33 was found cracked. The subject aeroplane had previously been modified in accordance with Airbus SB A300-57-6053 (Airbus Modification 10453).
This condition, if not corrected, could result in a deterioration of the structural integrity of the frame.
As no fatigue maintenance tasks (Inspection SB or Airworthiness Limitation Item) presently exist to inspect the affected area for aeroplanes having incorporated Airbus Modification 10453 preventively (without preliminary crack finding), Airbus has developed a new inspection [for cracking, and repair if necessary] to ensure structural integrity of the concerned area of frame 40.
You may obtain further information by examining the MCAI in the AD docket.
Airbus has issued the following service information. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.
We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD.
Based on the service information, we estimate that this proposed AD would affect about 153 products of U.S. registry. We also estimate that it would take about 3 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $36,720, or $240 per product.
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. “Subtitle VII: ( printed page 55487) Aviation Programs,” describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in “Subtitle VII, Part A, Subpart III, Section 44701: General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD 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.
For the reasons discussed above, I certify 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. 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.
We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.
Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
1. The authority citation for part 39 continues to read as follows:
2. The FAA amends § 39.13 by adding the following new AD:
Airbus: Docket No. FAA-2009-0993; Directorate Identifier 2009-NM-089-AD.
(a) We must receive comments by December 14, 2009.
(b) None.
(c) This AD applies to Airbus airplanes, certificated in any category, as identified in paragraphs (c)(1) and (c)(2) of this AD.
(1) Model A300 B4-2C, B4-103, and B4-203 airplanes, all serial numbers, modified preventively in service (without preliminary crack findings) in accordance with Airbus Service Bulletin A300-53-0297 (Airbus Modification 10453).
(2) Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R airplanes, all serial numbers, modified preventively in service (without preliminary crack findings) in accordance with Airbus Service Bulletin A300-57-6053 (Airbus Modification 10453).
For airplanes on which Airbus Service Bulletin A300-53-0297 or A300-57-6053 (Airbus Modification 10453), as applicable, have been incorporated as a corrective action (repair following crack finding), no action is required by this AD.
(d) Air Transport Association (ATA) of America Code 53: Fuselage.
(e) The mandatory continuing airworthiness information (MCAI) states:
One A300-600 aeroplane operator reported that, during a routine inspection, the Right Hand frame 40 forward fitting between stringer 32 and stringer 33 was found cracked. The subject aeroplane had previously been modified in accordance with Airbus SB A300-57-6053 (Airbus Modification 10453).
This condition, if not corrected, could result in a deterioration of the structural integrity of the frame.
As no fatigue maintenance tasks (Inspection SB or Airworthiness Limitation Item) presently exist to inspect the affected area for aeroplanes having incorporated Airbus Modification 10453 preventively (without preliminary crack finding), Airbus has developed a new inspection [for cracking, and repair if necessary] to ensure structural integrity of the concerned area of frame 40.
(f) Unless already done, do the following actions.
(1) At the applicable time specified in Table 1 of this AD: Do a one-time detailed visual inspection of the forward fitting at frame 40 on both sides of the airplane, in accordance with Airbus Mandatory Service Bulletin A300-57A6108 (for Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R airplanes) or A300-53A0387 (for Model A300 B4-2C, B4-103, and B4-203 airplanes), both including Appendices 01 and 02, both dated September 12, 2008.
