[Federal Register Volume 81, Number 8 (Wednesday, January 13, 2016)] [Proposed Rules] [Pages 1570-1573] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-33173] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-8428; Directorate Identifier 2014-NM-032-AD] RIN 2120-AA64 Airworthiness Directives; Airbus Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-17- 09 for all Airbus Model A330-200 series airplanes, -200 Freighter series airplanes, and -300 series airplanes, and AD 2012-25-12, for all Airbus Model A330-200 series airplanes and -300 series airplanes. AD 2011-17-09 currently requires revisions to certain operator maintenance documents to include new inspections. AD 2012-25-12 currently requires replacing certain main landing gear (MLG) bogie beams before reaching new reduced life limits. Since we issued AD 2011-17-09 and AD 2012-25- 12, we have determined that more restrictive instructions and/or airworthiness limitations should be incorporated into the maintenance or inspection program, as applicable. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This AD results from revisions to the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to include new or more restrictive life limits and/or replacements. We are proposing this AD to detect and correct fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane. DATES: We must receive comments on this proposed AD by February 29, 2016.

Discussion On August 2, 2011, we issued AD 2011-17-09, Amendment 39-16773 (76 FR 53305, August 26, 2011). AD 2011-17-09 requires actions intended to address an unsafe condition on all Airbus Model A330-200 series airplanes, -200 Freighter series airplanes, and -300 series airplanes. On December 5, 2012, we issued AD 2012-25-12, Amendment 39-17293 (77 FR 75825, December 26, 2012). AD 2012-25-12 requires actions intended to address an unsafe condition for all Airbus Model A330-200 series airplanes and -300 series airplanes. Since we issued AD 2011-17-09, Amendment 39-16773 (76 FR 53305, August 26, 2011), and AD 2012-25-12, Amendment 39-17293 (77 FR 75825, December 26, 2012), we have determined that more restrictive instructions and/or airworthiness limitations should be incorporated into the maintenance or inspection program, as applicable. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive, 2014-0009, dated January 8, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus Model A330-200 series airplanes, -200 Freighter series airplanes, and -300 series airplanes. The MCAI states: The airworthiness limitations for Airbus aeroplanes are currently published in Airworthiness Limitations Section (ALS) documents. The instructions and airworthiness limitations applicable to the Safe Life Airworthiness Limitation Items (SL ALI) are given in Airbus A330 ALS Part 1 and A340 ALS Part 1, which are approved by EASA. The revision 07 of Airbus A330 and A340 ALS Part 1 [dated September 23, 2013] introduces more restrictive instructions and/or airworthiness limitations. Failure to comply with this revision could result in an unsafe condition. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2012-0179 [http://ad.easa.europa.eu/blob/easa_ad_2012_0179_superseded.pdf/AD_2012-0179_1], which is superseded, and requires accomplishment of the actions specified in Airbus A330 or A340 ALS Part 1 revision 07 [dated September 23, 2013]. In addition, this [EASA] AD also supersedes EASA AD 2011-0122-E [http://ad.easa.europa.eu/blob/easa_ad_2011_0122_E_superseded.pdf/EAD_2011-0122-E_1] and EASA AD 2011-0212 [http://ad.easa.europa.eu/blob/easa_ad_2011_0212_superseded.pdf/AD_2011-0212_1], whose requirements have been transferred into Airbus A330 and A340 ALS Part 1 revision 07 [dated September 23, 2013]. The unsafe condition is fatigue cracking, damage, and corrosion in certain principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised structural inspection requirements. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-8428. Related Service Information Under 1 CFR Part 51 Airbus has issued Airbus A330 ALS Part 1, ''Safe Life Airworthiness Limitation Items,'' Revision 07, dated September 23, 2013. The service information describes Safe Life Airworthiness Limitation Items (SL ALI) for the landing gear. Airbus has also issued the following variations, which describe SL ALIs. Airbus A330 Variation to Revision 07 of ALS Part 1, ``Safe Life Airworthiness Limitations Items (SL ALI),'' dated September 24, 2013 (variations reference 0GVLG130005C0S, dated October 29, 2013). Airbus A330, ``Safe Life Airworthiness Limitations Items (SL ALI),'' Variation 7.6, dated February 24, 2015. Airbus A330, ``Safe Life Airworthiness Limitations Items (SL ALI),'' Variation 7.10, dated April 1, 2015. Airbus A330, ``Safe Life Airworthiness Limitations Items (SL ALI),'' Variation 7.19, dated June 8, 2015. Airbus A330, ``Safe Life Airworthiness Limitations Items (SL ALI),'' Variation 7.20, dated August 28, 2015.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM. FAA's Determination and Requirements of This Proposed AD 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. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (m) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure. Differences Between This Proposed AD and the MCAI or Service Information Although the applicability in the MCAI also identifies Airbus Model A340-200, -300, -500, and -600 series airplanes, this AD applies only to Airbus Model A330-200, -200 Freighter series airplanes, and -300 series airplanes. However, we might consider future separate rulemaking to require incorporating Airbus A340 ALS Part 1, ''Safe Life Airworthiness Limitation Items,'' Revision 07, dated September 23, 2013, into the maintenance program or inspection program, as applicable. There are currently no Airbus Model [[Page 1572]] A340 series airplanes on the U.S. Registry. Costs of Compliance We estimate that this proposed AD affects 82 airplanes of U.S. registry. The actions that are required by AD 2011-17-09, Amendment 39-16773 (76 FR 53305, August 26, 2011), and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2011-17-09 is $85 per product. The actions that are required by AD 2012-25-12, Amendment 39-17293 (77 FR 75825, December 26, 2012), and retained in this proposed AD take about 16 work-hours per product (2 MLG bogie beams per airplane), at an average labor rate of $85 per work-hour. Required parts cost about $255,000 per MLG bogie beam. Based on these figures, the estimated cost of the actions that were required by AD 2012-25-12 is up to $256,360 per MLG bogie beam. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $6,970, or $85 per product. Authority for This Rulemaking 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: 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. Regulatory Findings 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); 3. Will not affect intrastate aviation in Alaska; and 4. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
