[Federal Register Volume 83, Number 214 (Monday, November 5, 2018)] [Proposed Rules] [Pages 55299-55303] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-23689] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0903; Product Identifier 2018-NM-113-AD] RIN 2120-AA64 Airworthiness Directives; Airbus SAS Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 2016-19- 14, which applies to certain Airbus SAS Model A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2016-19-14 requires repetitive inspections for cracking of the 10VU rack fitting lugs, and repair of any cracking. Since we issued AD 2016-19-14, we have determined that the unsafe condition may exist on additional airplanes. This proposed AD continues to require repetitive inspections for cracking of the 10VU rack fitting lugs, and repair of any cracking. This proposed AD would also add airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by December 20, 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.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We issued AD 2016-19-14, Amendment 39-18663 (81 FR 71602, October 18, 2016) (``AD 2016-19-14''), for certain Airbus SAS Model A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2016-19-14 requires repetitive inspections for cracking of the 10VU rack fitting lugs, and repair of any cracking. AD 2016-19-14 resulted from a report of cracks found during maintenance inspections on certain 10VU rack fitting lugs. We issued AD 2016-19-14 to address reading difficulties of flight-critical information displayed to the flightcrew during a critical phase of flight, such as an approach or takeoff, which could result in loss of airplane control at an altitude insufficient for recovery. Actions Since AD 2016-19-14 Was Issued AD 2016-19-14 applies to the identified airplane models on which Airbus Modification 35869 has not been embodied in production. Since we issued AD 2016-19-14, we have determined that the unsafe condition may also exist on airplanes in a post-Airbus Modification 35869 configuration. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0131, dated June 19, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus SAS Model A318 and A319 series airplanes; A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The MCAI states: During an unscheduled maintenance operation on an A330 aeroplane, the 10VU rack was removed for access and cracks were discovered on 10VU rack side fittings on lugs 1, 3 and 4. As a similar design is installed on A320 family aeroplanes, a sampling review was done to determine the possible fleet impact. The result showed that several aeroplanes had cracked or broken 10VU rack side fittings. This condition, if not detected and corrected, could lead to a high vibration level on the primary flight and navigation displays during critical flight phases (take-off and landing), possibly creating reading difficulties for the crew. Prompted by these findings, Airbus developed mod 35869 to reinforce the affected rack fitting lugs. For in-service aeroplanes, Airbus published SB [service bulletin] A320-92-1087 to provide detailed inspection (DET) and repair instructions. Consequently, EASA AD 2015-0170 [which corresponds to FAA AD 2016-19-14] was issued to require, for all pre mod 35869 aeroplanes, repetitive DET of the affected 10VU rack fitting lugs and, depending on findings, accomplishment of a repair. Since that [EASA] AD was issued, analysis confirmed the need to extend the inspection to post mod 35869 aeroplanes. Airbus issued SB A320-92-1119 providing instructions for DET and repair of those aeroplanes accordingly. Airbus developed mod 157335 to further reinforce and adjust the affected rack fitting lugs. Analysis is still ongoing to confirm mod 157335 as terminating action for the requirements of this [EASA] AD, and further AD action may follow. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2015-0170, which is superseded, expanding the Applicability to include post mod 35869 aeroplanes, and requiring, for all aeroplanes, repetitive DET of the affected 10VU rack fitting lugs and, depending on findings, accomplishment of a repair [and reporting positive and negative findings to Airbus]. 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- 0903. Model A320-216 Airplanes The Airbus SAS Model A320-216 was type certificated on December 19, 2016. Before that date, any EASA ADs that affected Model A320-216 airplanes were included on the Required Airworthiness Actions List (RAAL). One or more Model A320-216 airplanes have subsequently been placed on the U.S. Register, and will now be included in FAA AD actions. For Model A320-216 airplanes, the requirements that correspond to AD 2014-20-04 were mandated by the MCAI via the RAAL. Although that RAAL requirement is still in effect, for continuity and clarity we have identified Model A320-216 airplanes in paragraph (c) of this AD; the requirements of paragraphs (g) through (i) in this proposed AD would therefore apply to those airplanes. Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletins A320-92-1087, Revision 03, dated July 31, 2017; and A320-92-1119, dated July 28, 2017. This service information describes procedures for repetitive inspections for cracking of the 10VU rack fitting lugs, and repair of any cracking. These documents are distinct since they apply to airplanes in different configurations. 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 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 [[Page 55301]] on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would retain all of the requirements of AD 2016- 19-14 and expand the applicability to include additional airplanes. This proposed AD would require accomplishing the actions specified in the service information described previously except as discussed under ``Differences Between this Proposed AD and the MCAI or Service Information.'' This proposed AD also would require sending the inspection results to Airbus SAS. Differences Between This Proposed AD and the MCAI or Service Information This proposed AD would not permit further flight if cracks are detected in any 10VU rack fitting lug, but the MCAI permits flight for a limited time if cracking is detected in a single 10VU rack fitting lug. We have determined that, because of the safety implications and consequences associated with that cracking, any cracked 10VU rack fitting lug must be repaired before further flight. This difference has been coordinated with the EASA. Costs of Compliance We estimate that this proposed AD affects 461 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 2 work-hours x $85 per hour = $170........................... $0 $170 $78,370 ---------------------------------------------------------------------------------------------------------------- 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. We estimate the following costs to do any necessary repairs that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need these repairs: Estimated Costs of On-Condition Actions ------------------------------------------------------------------------ Cost per Labor cost Parts cost product ------------------------------------------------------------------------ 83 work-hours x $85 per hour = $7,055. $9,140 $16,195 ------------------------------------------------------------------------ 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 and associated appliances 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, [[Page 55302]] the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2016-19-14, Amendment 39-18663 (81 FR 71602, October 18, 2016), and adding the following new AD: Airbus SAS: Docket No. FAA-2018-0903; Product Identifier 2018-NM- 113-AD.
