[Federal Register Volume 83, Number 182 (Wednesday, September 19, 2018)] [Proposed Rules] [Pages 47318-47321] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-20099] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0167; Product Identifier 2017-NM-131-AD] RIN 2120-AA64 Airworthiness Directives; ATR-GIE Avions de Transport R[eacute]gional Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposal for all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. This action revises the notice of proposed rulemaking (NPRM) by increasing the number of affected parts that must be inspected. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, we are reopening the comment period to allow the public the chance to comment on these changes. DATES: The comment period for the NPRM published in the Federal Register on March 29, 2018 (83 FR 13436), is reopened. We must receive comments on this SNPRM by November 5, 2018.

We will also post a report summarizing each substantive verbal contact we receive about this SNPRM. Discussion We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and [[Page 47319]] Model ATR72 airplanes. The NPRM published in the Federal Register on March 29, 2018 (83 FR 13436). The NPRM was prompted by reports of cracking in main landing gear (MLG) universal joints (U-joints). The NPRM proposed to require repetitive detailed inspections of the affected U-joints for cracks, and replacement if necessary. The NPRM also provided an optional terminating action for the repetitive inspections. Actions Since the NPRM Was Issued Since we issued the NPRM, the number of affected parts that must be inspected has increased. In addition, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, issued EASA Airworthiness Directive 2018-0080, dated April 11, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), which supersedes EASA AD 2017-0172, dated September 7, 2017 (referred to in the NPRM). The MCAI was issued to correct an unsafe condition on all ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. The MCAI states: Occurrences were reported of finding cracks in certain MLG U- joints. Subsequent investigation identified a batch of affected U- joints which have possibly been subjected to non-detected thermal abuse during the grinding process by the U-joint manufacturer in production, or by a maintenance organization during overhaul and/or repair. This condition, if not detected and corrected, could lead to MLG structural failure and subsequent collapse of the MLG, possibly resulting in damage to the aeroplane and injury to the occupants. To address this potential unsafe condition, SLS [Safran Landing Systems] published the applicable SB [service bulletin] to provide inspection instructions. Consequently, EASA issued AD 2017-0172 to require repetitive detailed visual inspection (DVI) of the affected U-joints for cracks, and, depending on findings, replacement. Since that AD was issued, SLS identified that certain s/n [serial numbers] of affected U-joints were inadvertently not included in the list of the original issue of the applicable SB. Consequently, SLS issued Revision 02 of the applicable SB to clarify the s/n tables of P/N [part number] D56805 and P/N D56805-2, and to add those missed s/n of affected U-joints. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2017-0172, which is superseded, and includes reference to Revision 02 of the applicable SB. 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- 0167. Related Service Information Under 1 CFR Part 51 Safran Landing Systems has issued Service Bulletin 631-32-249, Revision 2, dated February 13, 2018; Service Bulletin 631-32-250, Revision 2, dated February 13, 2018; and Service Bulletin 631-32-251, Revision 2, dated February 13, 2018. The service information describes procedures for detailed inspections of the affected U-joints for cracking, and replacement if necessary. These documents are distinct since they apply to different airplane models. 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. Comments We gave the public the opportunity to participate in developing this proposed AD. We considered the comment received. Request To Refer to Revised Service Information Empire Airlines requested that we refer to Service Bulletin 631-32- 249, Revision 2, dated February 13, 2018; Service Bulletin 631-32-250, Revision 2, dated February 13, 2018; and Service Bulletin 631-32-251, Revision 2, dated February 13, 2018, because the number of affected parts increased with these revisions. We agree with the commenter's request. We have revised this proposed AD to refer to the new service bulletins. We have given credit for affected parts listed in Service Bulletin 631-32-249, Revision 1, dated June 26, 2017; Service Bulletin 631-32-250, Revision 1, dated June 26, 2017; and Service Bulletin 631-32-251, Revision 1, dated June 26, 2017. Any affected parts not identified in Revision 1 of the applicable service bulletins must still comply with the requirements of paragraphs (h) and (i) of this proposed AD. FAA's Determination and Requirements of This SNPRM 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 these same type designs. Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Costs of Compliance We estimate that this proposed AD affects 62 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection..................... 1 work-hour x $85 per $0 $85 per inspection $5,270 per hour = $85 per cycle. inspection inspection cycle. cycle. ---------------------------------------------------------------------------------------------------------------- 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: [[Page 47320]] On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replacement............................... 8 work-hours x $85 per hour = $680 $14,083 $14,763 ---------------------------------------------------------------------------------------------------------------- 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 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.
