[Federal Register Volume 81, Number 124 (Tuesday, June 28, 2016)] [Proposed Rules] [Pages 41886-41889] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-14969] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-0831; Directorate Identifier 2014-NM-061-AD] RIN 2120-AA64 Airworthiness Directives; Airbus Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposed airworthiness directive (AD) for all Airbus Model A318 and A319 series airplanes, A320-211, - 212, -214, -231, -232, and -233 airplanes, and A321 series airplanes. The NPRM proposed to require an inspection to identify the part number and serial number of the main landing gear (MLG) sliding tubes installed on the airplane; and inspection of affected chromium plates for damage; an inspection of affected sliding tube axles for damage; and replacement of the sliding tube if necessary. The NPRM was prompted by a report of a rupture of a MLG sliding tube axle. This action revises the NPRM by removing certain service information that does not adequately address the identified unsafe condition and revising the compliance method. We are proposing this supplemental NPRM (SNPRM) to detect and correct cracks in the axle and (partial) detachment of the axle and wheel from the sliding tube, which could result in failure of an MLG. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. DATES: We must receive comments on this SNPRM by August 12, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A318 and A319 series airplanes, A320-211, -212, -214, -231, -232, and -233 airplanes, and A321 series airplanes. The NPRM published in the Federal Register on April 24, 2015 (80 FR 22939) (``the NPRM''). The NPRM was prompted by a report of a rupture of a MLG sliding tube axle. The NPRM proposed to require an inspection to identify the part number and serial number of the MLG sliding tubes installed on the airplane; and an inspection of the axle on certain MLG sliding tubes for damage, and replacement of the sliding tube if necessary. Actions Since Previous NPRM Was Issued Since we issued the NPRM, we have determined that Messier-Bugatti- Dowty Service Bulletin 200-32-313, dated February 25, 2013, including Appendices A, B, and C, dated February 25, 2013; and Service Bulletin 201-32-62, including Appendices A, B, and C, dated February 25, 2013; do not adequately address the identified unsafe condition because this service information does not include all Required for Compliance steps required in Airbus Service Bulletin A320-32-1416, including Appendix 01, dated March 10, 2014. Therefore, this SNPRM proposes revising the service information specified for accomplishing the proposed actions. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0058, dated March 11, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus Model A318 and A319 series airplanes, A320-211, -212, -214, -231, -232, and -233 airplanes, and A321 series airplanes. The MCAI states: A main landing gear (MLG) sliding tube axle rupture occurred in service. Investigation of the affected part showed that [[Page 41887]] this failure was due to an abnormal grinding operation during overhaul by a certain maintenance and repair organization located in Singapore. A population of MLG sliding tubes was subsequently identified whose axles may have been subject to this grinding operation, which may have resulted in areas of residual stress on the axles on the MLG sliding tubes. In addition, the MSN [manufacturer serial number] of the aeroplanes which are known to have had the affected parts installed have been identified. This condition, if not detected and corrected, could lead to cracks in the axle and (partial) detachment of axle and wheel from the sliding tube, possibly resulting in failure of a MLG with consequent damage to the aeroplane and injury to occupants. To address this potential unsafe condition, Messier-Bugatti- Dowty, the MLG gear manufacturer, issued Service Bulletin (SB) 200- 32-313 and SB 201-32-62 [both dated February 25, 2013], providing inspection instructions and criteria for removal from service of the affected MLG sliding tubes. For the reasons described above, this [EASA] AD requires a one- time Special Detailed Inspection (SDI) of the axle on the affected MLG sliding tubes and, depending on findings, replacement of the MLG sliding tube. The SDI includes a detailed visual inspection of the chromium plate for damage, and a Barkhausen noise inspection of the sliding tube axles for damage. 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- 0831. Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletin A320-32-1416, dated March 10, 2014, including Appendix 01, dated March 10, 2014. This service information describes procedures for inspecting MLG axles and brake flanges by doing a detailed visual inspection of the chromium plates for damage, and a Barkhausen noise inspection of the sliding tube axles for damage, and replacement of affected parts if necessary. 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. Comments We gave the public the opportunity to participate in developing this proposed AD. We considered the comments received. Request To Revise Parts Installation Limitation American Airlines requested that we revise paragraphs (l)(1) and (l)(2) of the proposed AD (in the NPRM) to allow installation of serviceable MLG sliding tubes that have passed the inspection required by paragraph (i) of the proposed AD (in the NPRM). American Airlines stated that it believes that this is the intent of the MCAI. We agree with the commenter's request and have revised paragraphs (l)(1) and (l)(2) of this proposed AD accordingly. Additional Changes to This SNPRM We have removed Messier-Bugatti-Dowty Service Bulletin 200-32-313, including Appendices A, B, and C, dated February 25, 2013; and Service Bulletin 201-32-62, including Appendices A, B, and C, dated February 25, 2013; as sources of service information in this SNPRM. We have specified Airbus Service Bulletin A320-32-1416, including Appendix 01, dated March 10, 2014, as the appropriate source of service information for accomplishing the proposed actions. FAA's Determination and Requirements of This SNPRM 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 these same type designs. Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Differences Between This SNPRM and the MCAI or Service Information The effectivity in Airbus Service Bulletin A320-32-1416, including Appendix 01, dated March 10, 2014, does not include Model A318 series airplanes. This SNPRM specifies using the procedures specified for Model A319 series airplanes in Airbus Service Bulletin A320-32-1416, including Appendix 01, dated March 10, 2014, for accomplishing the proposed actions on Model A318 series airplanes. Costs of Compliance We estimate that this SNPRM affects 3 airplanes of U.S. registry. We also estimate that it would take about 18 work-hours per product to comply with the basic requirements of this SNPRM. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this SNPRM on U.S. operators to be $4,590, or $1,530 per product. In addition, we estimate that any necessary on-condition actions would take about 3 work-hours, for a cost of $255 per product. We have received no definitive data that would enable us to provide part cost estimates for the on-condition actions specified in this SNPRM. We have no way of determining the number of aircraft that might need these actions. 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. [[Page 41888]] List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
