Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of cracked and corroded barrel nuts found at the mid-spar location of the horizontal-stabilizer-to-vertical-stabilizer attachment joint. This AD requires repetitive detailed [[Page 88624]] inspections of each barrel nut and cradle, a check of the bolt torque of the preload indicating (PLI) washers, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective January 12, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of January 12, 2017.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc. Model DHC-8-400 airplanes. The NPRM published in the Federal Register on March 14, 2016 (81 FR 13298) (``the NPRM''). The NPRM was prompted by reports of cracked and corroded barrel nuts found at the mid-spar location of the horizontal-stabilizer-to-vertical-stabilizer attachment joint. The NPRM proposed to require repetitive detailed inspections of each barrel nut and cradle, a check of the bolt torque of the PLI washers, and corrective action if necessary. We are issuing this AD to detect and correct cracked and corroded barrel nuts, which could compromise the structural integrity of the vertical-stabilizer attachment joints and lead to loss of control of the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, issued Canadian Airworthiness Directive CF-2015- 13, dated June 25, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model DHC-8-400 series airplanes. The MCAI states: There has been one in-service report of a cracked and corroded barrel nut, part number (P/N) DSC228-12, found at the mid-spar location of the horizontal stabilizer to vertical stabilizer attachment joint. There have also been two other reports of corroded barrel nuts found at mid-spar locations. Preliminary investigation determined that the cracking is initiated by corrosion. The corrosion may have been caused by inadequate cadmium plating on the barrel nut. Failure of the barrel nuts could compromise the structural integrity of the joint and could lead to loss of control of the aeroplane. This [Canadian] AD mandates initial and repetitive inspections of the barrel nuts [and cradles for cracks and corrosion] at each horizontal stabilizer to vertical stabilizer attachment joints. Required actions include a bolt preload check of the PLI washers and applicable corrective actions (retorque of the bolts and replacement of the barrel nut), a detailed inspection of cracked or broken barrel nuts for damaged bores of the fittings, replacement of barrel nuts, and repair of damage and corrosion. 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-2016- 4224. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment. Support for the NPRM The Air Line Pilots Association, International, and a commenter, Lara Gabrys, supported the intent of the NPRM. Request To Specify Revised Service Information The source of service information in the NPRM--Bombardier Alert Service Bulletin A84-55-04, Revision A, dated June 2, 2015--has been revised. Horizon Air requested that we revise the NPRM to refer to the latest version of the service information. We agree and have revised this final rule to identify Bombardier Alert Service Bulletin A84-55-04, Revision C, dated May 3, 2016, as the appropriate source of service information. The revised service information clarifies certain conditional actions; the major actions remain essentially unchanged. We have also revised paragraph (m) of this AD to include all earlier revisions as credit for prior accomplishment of the corresponding actions specified in this AD. Request for Terminating Action Commenter Lara Gabrys expressed concern about the unsafe condition and the lack of a permanent solution to address it. We acknowledge the commenter's concern, and point out that this final rule (as also specified in the NPRM) requires that operators submit their inspection findings to Bombardier. Then, based on those findings, Bombardier plans to develop a permanent solution to address the unsafe condition. If terminating action is developed, approved, and available, we might consider additional rulemaking. At this time, however, we are issuing this final rule as proposed. Request To Limit Required Actions Paragraphs (g)(1), (g)(2), (h)(1)(i), (h)(1)(ii), (i), and (k) of the proposed AD specified that certain actions be done in accordance with ``the Accomplishment Instructions'' of the referenced service information. Noting that ``the Accomplishment Instructions'' include paragraphs 3.A., ``Job Set-Up,'' and 3.C., ``Close Out,'' Horizon Air requested that the compliance method instead be limited to paragraph 3.B., ``Procedures''--the only section that corrects the unsafe condition. Horizon Air objected to the inclusion of the specified set- up and close-out procedures, which would restrict the operators' ability to perform other maintenance in conjunction with the incorporation of the service information. [[Page 88625]] We agree with the request, for the reasons provided by the commenter. We have revised paragraphs (g)(1), (g)(2), (h)(1)(i), (h)(1)(ii), (i), and (k) of this AD, as well as paragraph (h)(1) of this AD, to refer to paragraph 3.B., ``Procedures.'' Clarification of Applicability This AD affects Model DHC-8-400, -401, and -402 airplanes. The SUMMARY of the NPRM and paragraph (c) of the proposed AD identified the affected airplanes as ``Model DHC-8-400 airplanes.'' Model DHC-8-400 series airplanes consist of Model DHC-8-400, -401, and -402 airplanes and correspond to the affected airplanes identified in the MCAI. We have therefore revised the SUMMARY to identify the affected airplanes as certain ``Model DHC-8-400 series airplanes.'' We also revised paragraph (c) of this AD to identify the applicability as ``Model DHC- 8-400, -401, and -402 airplanes'' with serial numbers 4001 and subsequent. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes 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 correcting 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 AD. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Alert Service Bulletin A84-55-04, Revision C, dated May 3, 2016. The service information describes procedures for a detailed inspection and repair for cracks and corrosion of the barrel nuts and cradles, a bolt preload check of the PLI washers, applicable corrective actions, a detailed inspection and repair for corrosion and damage of the bores of the fittings, and replacement of the barrel nuts. Bombardier, Inc. has also issued Bombardier Repair Drawing (RD) 8/ 4-55-1143, Issue 1, dated May 21, 2015. The service information describes procedures for repairing corrosion and damage of the fitting bore. 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 76 airplanes of U.S. registry. We also estimate that it will take about 6 work-hours per product to comply with the basic requirements of this AD and 1 work-hour per product for reporting. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $45,220, or $595 per product. In addition, we estimate that any necessary follow-on actions would take about 4 work-hours, and require parts costing $8,881, for a cost of $9,221 per product. We have no way of determining the number of aircraft that might need this action. 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. Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. 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; 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.
