[Federal Register Volume 83, Number 121 (Friday, June 22, 2018)] [Proposed Rules] [Pages 29059-29061] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-13335] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0548; Product Identifier 2017-NM-184-AD] RIN 2120-AA64 Airworthiness Directives; Bombardier, Inc., Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This proposed AD was prompted by a report of broken P-clamps on the pressure relief line and the motive flow line in the left and right fuel tanks, and fouling conditions between the motive flow line and the collector tank partition wall in both fuel tanks. This proposed AD would require, depending on airplane configuration: Increasing the hole size in the collector tank partition wall, inspecting the motive flow line for damage, and replacing the associated grommet and motive flow line; replacing the affected single nut plate brackets and standoffs at the affected stations on the motive flow line and pressure relief line; and inspecting the motive flow line and vent line at certain wing stations, and inspecting the fuel tubes, to verify that an appropriate clearance has been maintained between the fuel tubes and their support brackets, and applicable corrective actions. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by August 6, 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.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF-2017-05R1, dated September 20, 2017 (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: Some operators have reported broken P-clamps on the pressure relief line and the motive flow line in the left and right fuel tanks. Fouling conditions were also reported to exist between the motive flow line and the collector tank partition wall in both fuel tanks. These issues affect the integrity of the electrical bonding paths throughout the fuel lines, which in turn may lead to lightning strike induced fuel tank ignition. The initial issue of this [Canadian] AD mandated design changes that mitigate the risk of lightning strike induced fuel tank ignition. Since the initial issue of this [Canadian] AD, Transport Canada has become aware that Bombardier (BA) Service Bulletin (SB) 84-28-19 Revision A, dated 4 November 2016, and the initial issue of BA SB 84-28-19, dated 16 August 2016, do not instruct operators to support the motive flow line and vent line at wing stations -371.019 and 371.019 in the left-hand and right-hand fuel tanks, respectively, and do not instruct operators to maintain appropriate clearance between the fuel tubes and their support brackets at wing stations - 371.019 and -209.019 in the left-hand fuel tank and wing stations 371.019 and 209.019 in the right-hand fuel tank. Revision 1 of this [Canadian] AD introduces Part III, which requires operators to inspect and correct the fuel tube installation on affected aeroplanes, as required, to maintain fuel tube support and clearance between the fuel tubes and their support brackets. Revision 1 of this [Canadian] AD also updates SB references. Required actions include, depending on airplane configuration, increasing the hole size in the collector tank partition wall, inspecting the motive flow line for damage, and replacing the associated grommet and motive flow line; replacing the affected single nut plate brackets and standoffs at the affected stations on the motive flow line and pressure relief line; and inspecting the motive flow line and vent line at certain wing stations, and inspecting the fuel tubes, to verify that an appropriate clearance has been maintained between the fuel tubes and their support brackets, and applicable corrective actions. Corrective actions include reworking the replaced parts. 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- 0548. [[Page 29060]] Related Service Information Under 1 CFR Part 51 Bombardier has issued Service Bulletin 84-28-18, Revision B, dated April 20, 2017. This service information describes procedures to increase the hole size in the collector tank partition wall, inspect the motive flow line for damage, and replace the associated grommet and motive flow line. Bombardier has also issued Service Bulletin 84-28-19, Revision C, dated September 1, 2017. This service information describes procedures to replace the affected single nut plate brackets and standoffs at the affected stations on the motive flow line and pressure relief line, inspect the motive flow line and vent line at certain wing stations, and inspect the fuel tubes to verify that an appropriate clearance has been maintained between the fuel tubes and their support brackets, and applicable corrective actions. The 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. 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 52 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspections and modifications.... Up to 21 work-hours Up to $6,152....... $7,937 Up to $412,724. x $85 per hour = $1,785. ---------------------------------------------------------------------------------------------------------------- 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.
