1 [Federal Register Volume 83, Number 200 (Tuesday, October 16, 2018)] [Rules and Regulations] [Pages ] From the Federal Register Online via the Government Publishing Office [ [FR Doc No: ] DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA ; Product Identifier 2017-NM-182-AD; Amendment ; AD ] RIN 2120-AA64 Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. SUMMARY: We are superseding Airworthiness Directive (AD) , which applied to all ATR-GIE Avions de Transport Régional Model ATR42 airplanes. AD required a onetime inspection to detect discrepancies (e.g., cracking, loose/sheared fasteners, distortion) on the lefthand and right-hand wings, of the outer wing box upper skin and upper rib feet, and repair if necessary. Since we issued AD , after initial findings had suggested the cracking was isolated to a few airplanes, we received reports of cracking in these same areas on other Model ATR42 airplanes. This AD requires repetitive inspections to detect discrepancies on the left-hand and right-hand wings, of the outer wing box upper skin and upper rib feet, and repair if necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective November 20, The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of November 20, ADDRESSES: For service information identified in this final rule, contact ATR-GIE Avions de Transport Régional, 1 Allée Pierre Nadot, Blagnac Cedex, France; telephone +33 (0) ; fax +33 (0) ; internet You may view this referenced service information at the FAA, Transport Standards Branch, 2200 South 216th St., Des Moines, WA.

2 Examining the AD Docket You may examine the AD docket on the internet at by searching for and locating Docket No. FAA ; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, the regulatory evaluation, any comments received, and other information. The address for Docket Operations (phone: ) is U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC FOR FURTHER INFORMATION CONTACT: Shahram Daneshmandi, Aerospace Engineer, International Section, Transport Standards Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; telephone and fax SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD , Amendment (71 FR 18205, April 11, 2006) ( AD ). AD applied to all ATR-GIE Avions de Transport Régional Model ATR42 airplanes. The NPRM published in the Federal Register on June 1, 2018 (83 FR 25419). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD , dated December 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or the MCAI ), to correct an unsafe condition for all ATR-GIE Avions de Transport Régional Model ATR42 airplanes. The MCAI states: Occurrence was reported of detecting cracks on the wing of one in-service ATR 42 aeroplane in The cracks were found on the upper feet of ribs and on the upper skin of the wing outer boxes. This condition, if not detected and corrected, could adversely affect the structural integrity of the aeroplane. To address this potential unsafe condition, ATR issued Service Bulletin (SB) ATR to provide inspection instructions and DGAC [Direction Générale de l'aviation Civile] France issued [French] AD F (EASA approval ) [which corresponds to FAA AD ] to require, for aeroplanes having accumulated more than 4,000 flight cycles (FC), a one-time Detailed Visual Inspection (DVI) of outer wing box upper skin and upper rib feet, on the right hand (RH) and left hand (LH) sides, from rib 24 to rib 29. After that [French] AD was issued, based on inspection results (all aeroplanes inspected, no similar case found), it was determined that these cracks were an isolated case. More recently, three other cases were reported, indicating that this may not be an isolated case and that cracks could occur in this area of the wings on other ATR 42 aeroplanes. Consequently, ATR published SB ATR (hereafter referred as ATR SB' in this [EASA] AD) to provide inspection instructions. 2
3 For the reasons described above, this [EASA] AD supersedes DGAC France AD F and requires repetitive DVI of the same wing areas and, depending on findings, accomplishment of a repair. You may examine the MCAI in the AD docket on the internet at by searching for and locating Docket No. FAA Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA's response. Request To Refer to Latest Service Information Empire Airlines stated that paragraphs (g) and (i) of the proposed AD refer to ATR Service Bulletin ATR , dated October 19, Empire Airlines also stated that service bulletin has been revised. We infer that Empire Airlines requested that the references in paragraphs (g) and (i) of this AD be revised to refer to ATR Service Bulletin ATR , Revision 01, dated January 8, We agree to refer to the latest revision of the service information since the changes introduced in this revision do not affect the AD requirements. We have revised paragraphs (g) and (i) of this AD accordingly. We have also added paragraph (k) to this AD to provide credit for accomplishing ATR Service Bulletin ATR , dated October 19, Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule with the change described previously and minor editorial changes. We have determined that these minor changes: Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 ATR-GIE Avions de Transport Régional has issued ATR Service Bulletin ATR , Revision 01, dated January 8, This service information describes procedures for inspecting the outer wing box upper skin and upper rib feet, on the left-hand and right-hand wings, for discrepancies. 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. Costs of Compliance We estimate that this AD affects 37 airplanes of U.S. registry. We estimate the following costs to comply with this AD: 3
4 Estimated Costs Action Labor cost Parts cost Inspection 6 work-hours $85 per hour = $510 per inspection cycle Reporting 1 work-hour $85 per hour = $85 per inspection cycle Cost per product $0 $510 per inspection cycle 0 $85 per inspection cycle Cost on U.S. operators $18,870 per inspection cycle. $3,145 per inspection cycle. We have received no definitive data that would enable us to provide cost estimates for the oncondition actions specified in this AD. 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 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 AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order C. 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 AD will not have federalism implications under Executive Order This AD will 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 that this AD: 1. Is not a significant regulatory action under Executive Order 12866; 4
5 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.
