[Federal Register Volume 83, Number 215 (Tuesday, November 6, 2018)] [Proposed Rules] [Pages 55498-55502] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-24020] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0907; Product Identifier 2018-NM-118-AD] RIN 2120-AA64 Airworthiness Directives; Airbus SAS Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- [[Page 55499]] SUMMARY: We propose to supersede Airworthiness Directive (AD) 2017-07- 05, which applies to all Airbus SAS Model A300 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 2017-07-05 requires repetitive detailed visual inspections of the main landing gear (MLG) leg components and replacement of the MLG leg if cracked components are found. Since we issued AD 2017-07-05, further investigation revealed that overhaul of the MLG does not alleviate the need for inspecting the MLG hinge arm/ barrel pin for cracking. This proposed AD would retain the requirements of AD 2017-07-05 and remove the credit for doing a MLG overhaul in lieu of the initial inspection of the MLG leg components. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by December 21, 2018. 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.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2018-0907; Product Identifier 2018-NM-118-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 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. Discussion We issued AD 2017-07-05, Amendment 39-18843 (82 FR 16101, April 3, 2017) (``AD 2017-07-05''), for all Airbus SAS Model A300 series airplanes; and Model A300-600 series airplanes. AD 2017-07-05 requires repetitive detailed visual inspections of the MLG leg components and replacement of the MLG leg if cracked components are found. AD 2017-07- 05 resulted from reports of cracks in MLG leg components. We issued AD 2017-07-05 to address cracking of certain components in the MLG leg, which could result in a MLG collapse, and consequent damage to the airplane and injury to the airplane occupants. Actions Since AD 2017-07-05 Was Issued Since we issued AD 2017-07-05, further investigation revealed that overhaul of the MLG does not alleviate the need for inspecting the MLG hinge arm/barrel pin for cracking. This proposed AD would retain the requirements of AD 2017-07-05 and remove the credit for substituting MLG overhaul in lieu of the initial inspection of the MLG leg components. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0170, dated August 6, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus SAS Model A300 series airplanes; and Model A300-600 series airplanes. The MCAI states: Two cases were reported of finding a cracked MLG hinge arm/ barrel pin, one was discovered in service during a maintenance task and the other one was identified during MLG overhaul. This condition, if not detected and corrected, could lead to MLG collapse, possibly resulting in damage to the aeroplane and injury to occupants. To address this potential unsafe condition, Airbus issued [Alert Operators Transmission] AOT A32W008-16 (original issue) to provide instructions for detailed visual inspections (DET) to detect cracks and EASA issued AD 2016-0058 accordingly [which corresponds to FAA AD 2017-07-05], requiring repetitive DET of the affected parts and, depending on findings, replacement of the affected MLG leg. Since that AD was issued, further investigation results highlighted that, the overhaul of the MLG cannot alleviate the inspection need of the hinge arm/barrel pin. For the reasons described above, this [EASA] AD retains the requirement of EASA AD 2016-0058, which is superseded, removing the credit of MLG overhaul for the first inspection of the pin. 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-2018- 0907. Related Service Information Under 1 CFR Part 51 Airbus has issued Alert Operators Transmission (AOT) A32W008-16, Rev 01, dated July 30, 2018, including Appendixes 1 through 4. This service information describes procedures for inspecting the MLG hinge arm/barrel pin for cracking, and replacement of the MLG leg if cracking is detected. 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. FAA's Determination 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 [[Page 55500]] MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of this NPRM This proposed AD would retain all requirements of AD 2017-07-05. This proposed AD would require repetitive detailed visual inspections of the MLG leg components for cracking and replacement of the MLG leg if cracked components are found. This proposed AD also would require reporting the findings of each inspection by sending the inspection results to Airbus SAS. Costs of Compliance We estimate that this proposed AD affects 128 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- Labor cost Parts cost Cost per product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- 1 work-hour x $85 per hour = $85, $0 $85, per inspection cycle... $10,880, per inspection per inspection cycle. cycle. ---------------------------------------------------------------------------------------------------------------- Estimated Costs of On-Condition Actions ------------------------------------------------------------------------ Labor cost Parts cost Cost per product ------------------------------------------------------------------------ 20 work-hours x $85 per hour = $3,400,000 per MLG $3,401,700 per $1,700 per MLG. MLG. ------------------------------------------------------------------------ We estimate that it would take about 1 work-hour per product to comply with the reporting requirement in this proposed AD. The average labor rate is $85 per hour. Based on these figures, we estimate the cost of reporting the inspection results on U.S. operators to be $85 per product. The new requirements of this proposed AD add no additional economic burden. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120- 0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES-200. 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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.
