[Federal Register Volume 83, Number 102 (Friday, May 25, 2018)] [Proposed Rules] [Pages 24244-24248] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-11134] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0417; Product Identifier 2017-NM-132-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) 2016-25- 03, which applies to certain Airbus Model A300 F4-600R series airplanes. AD 2016-25-03 requires repetitive high frequency eddy current (HFEC) inspections of the aft lower deck cargo door (LDCD) frame forks; a one-time check of the LDCD clearances; and a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. Since we issued AD 2016-25-03, we have determined that accomplishing a new frame fork repair or reinforcement would allow an extension of the repetitive inspection intervals as would a frame fork replacement. This proposed AD would retain the actions required by AD 2016-25-03, with revised corrective actions and compliance times. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by July 9, 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 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 2016-25-03, Amendment 39-18729 (81 FR 93801, December 22, 2016) (``AD 2016-25-03''), for certain Airbus Model A300 F4-600R series airplanes. AD 2016-25-03 requires repetitive HFEC inspections of the aft LDCD frame forks; a one-time check of the LDCD clearances; and a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. AD 2016-25-03 resulted from a report of two adjacent frame forks that were found cracked on the aft LDCD of two Model A300-600F4 airplanes during scheduled maintenance. We issued AD 2016-25-03 to detect and correct cracked or ruptured aft LDCD frames, which could allow loads to be transferred to the remaining structural elements. This condition could lead to the rupture of one or more vertical aft LDCD frames, which could result in reduced structural integrity of the aft LDCD. Actions Since AD 2016-25-03 Was Issued Since we issued AD 2016-25-03, we have determined that accomplishing a new frame fork repair or reinforcement would allow an extension of the repetitive inspection intervals as would the existing frame fork replacement. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0152R1, dated May 23, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Airbus Model A300 F4-600R series airplanes. The MCAI states: During scheduled maintenance at frames (FR) 61 and FR61A on the aft lower deck cargo door (LDCD) of two A300-600F4 aeroplanes, two adjacent frame forks were found cracked. Subsequent analysis determined that, in case of cracked or ruptured aft cargo door frame(s), loads will be transferred to the remaining structural elements. However, these secondary load paths will be able to sustain the loads for a limited number of flight cycles only. This condition, if not detected and corrected, could lead to the rupture of one or more vertical aft cargo door frame(s), resulting in reduced structural integrity of the aft cargo door. To address this unsafe condition, Airbus issued Alert Operators Transmission (AOT) A52W011-15 to provide inspection instructions, and, consequently, EASA issued AD 2015-0152 [which corresponds to FAA AD 2016-25-03] to require repetitive inspections of the aft LDCD frame forks and, depending on findings, the accomplishment of applicable corrective action(s). Since that AD was issued, Airbus published Service Bulletin (SB) SB A300-52-6085 which provides frame fork reinforcement instruction and SB A300-52-6086 which provides instruction to inspect the cargo door for cracks as well as frame fork replacement instructions having the inspection interval extended from 600 flight cycles (FC) to 1,200 FC. For the reason described above, this [EASA] AD is revised to introduce frame forks replacement or repair [or reinforcement] as an allowance to extend the inspection interval. Required actions include repetitive HFEC inspections of the aft LDCD frame forks and repair, reinforcement, or replacement if necessary; a one-time check of the LDCD clearances and adjustment if necessary; and a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops for wear, and corrective actions if necessary. Corrective actions include blend-out, adjustment, and replacement of hooks, bushes and x-stops. 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-2018-0417. Related Service Information Under 1 CFR Part 51 Airbus has issued the following service information: Alert Operators Transmission--AOT A52W011-15, Revision 00, dated July 23, 2015, which describes procedures for a check of the aft LDCD clearances ``U'' and ``V'' between the latching hooks and the eccentric bush at frame (FR)60 through FR64A and an adjustment of the latching hook; a detailed inspection to detect signs of wear of the hooks, eccentric bushes, and x-stops and corrective actions; and an HFEC inspection to detect cracking at all frame fork stations of the aft LDCD and a replacement of the frame fork. Service Bulletin A300-52-6085, Revision 00, dated December 22, 2016. This service information describes procedures for reinforcing frame fork fastener holes, which include related investigative and corrective actions. The related investigative actions include a rotating probe inspection for cracking of the fastener holes and a check to determine the hole diameter. Corrective actions include repair and cold working the fastener holes. Service Bulletin A300-52-6086, Revision 00, dated December 25, 2016, which describes procedures for a check of the aft LDCD clearances ``U'' and ``V'' between the latching hooks and the eccentric bush at FR60 through FR64A and an adjustment of the latching hook; and HFEC inspection to detect cracking at all frame fork stations of the aft LDCD and a repair of the frame fork. 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. [[Page 24246]] 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. Costs of Compliance We estimate that this proposed AD affects 58 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs for Required Actions ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 17 work-hours x $85 per hour = $1,445........................ $0 $1,445 $83,810 ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. We have no way of determining the number of aircraft that might need these on-condition actions: Estimated Costs of On-Condition Actions ------------------------------------------------------------------------ Cost per Labor cost Parts cost product ------------------------------------------------------------------------ Up to 65 work-hours x $85 per hour = $10,000 $15,525 $5,525............................... ------------------------------------------------------------------------ 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. 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) 2016-25-03, Amendment 39-18729 (81 FR 93801, December 22, 2016), and adding the following new AD: Airbus: Docket No. FAA-2018-0417; Product Identifier 2017-NM-132-AD.
