 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2018-1063; Product Identifier 2018-NM-160-AD]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Notice of proposed rulemaking (NPRM).
 SUMMARY: We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-223, A330-223F, A330-321, A330-322, and A330-323 airplanes. This proposed AD was prompted by a report of fatigue cracking in the latch beam gussets on a certain thrust reverser (T/R). This proposed AD would require a one-time special detailed inspection of certain latch beam gussets of certain T/Rs for cracks, and modifying the latch beam gussets of the T/Rs, if necessary. We are proposing this AD to address the unsafe condition on these products.
 DATES: We must receive comments on this proposed AD by February 11, 2019.

Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0227, dated October 22, 2018 (“EASA AD 2018-0227”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for all Airbus SAS Model A330-223, A330-223F, A330-321, A330-322, A330-323 airplanes. The MCAI states: A report was received of an in-service occurrence where an operator found a crack in the latch beam gussets of an affected TR [thrust reverser], between the forward (L2) and middle (L3) latches, adjacent to the aft cascade frame attachment bracket in the 6 o'clock beam. Subsequent investigation revealed that the crack surface of the latch beam gusset showed indication of high fatigue cycle, leading to development of a design modification, reinforcing the latch beam gussets. This was introduced through Airbus production mod 48539 (improvement of 6 o'clock latch beam) and Airbus issued the modification SB [Airbus Service Bulletin A330-78-3014, dated May 9, 2001] as a recommendation for in-service aeroplanes. Since these measures were introduced, a new case was reported of finding a crack beyond prediction at the latch beam gusset of an affected TR, on which the recommended modification SB had not been accomplished. This condition, if not detected and corrected, could lead to crack propagation until part failure and potentially departure of TR cascade during TR operation, which could create runway hazards for other aeroplanes [which could result in damage to the airplane and hazards to persons or property on the ground]. To address this potential unsafe condition, Airbus issued the inspection SB [Airbus Service Bulletin A330-78-3024, dated June 28, 2018] to provide instructions for special detailed inspection (SDI) of the latch beam gussets. For the reasons described above, this [EASA] AD requires a one-time SDI of the latch beam gussets between the forward and middle latches of the affected TR [for cracks] and, depending on findings, replacement with improved (reinforced, modified) TR latch beam gussets. Related IBR Material Under 1 CFR Part 51 EASA AD 2018-0227 describes procedures for a one-time special detailed inspection of the latch beam gussets between the forward and middle latches of the affected T/R for cracks and modifying the latch beam gussets. This material 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 and it is publicly available through the EASA website. 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 
                    ( print page 67159)
                    MCAI 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. Explanation of Required Compliance Information In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. As a result, EASA AD 2018-0227 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with the provisions specified in EASA AD 2018-0227, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in EASA AD 2018-0227 that is required for compliance with EASA AD 2018-0227 will be available on the internet at 
                    *http://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2018-1063 after the FAA final rule is published. Costs of Compliance We estimate that this proposed AD affects 9 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

                             product

 According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our cost estimate. 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.
