[Federal Register Volume 83, Number 43 (Monday, March 5, 2018)] [Rules and Regulations] [Pages 9178-9181] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-03824] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2017-0900; Product Identifier 2017-NM-055-AD; Amendment 39-19208; AD 2018-04-12] RIN 2120-AA64 Airworthiness Directives; The Boeing Company Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, -500 series airplanes. This AD was prompted by a report of wire damage on a fuel boost pump power cable, and a separate report of a fuel tank explosion on a similarly equipped airplane. This AD requires the installation of new shielded wire bundles and convoluted liners within fuel tank conduits, and revision of the maintenance or inspection program, as applicable, to incorporate certain airworthiness limitations (AWLs). We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective April 9, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 9, 2018.

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 all The Boeing Company Model 737-100, -200, -200C, -300, -400, -500 series airplanes. The NPRM published in the Federal Register on September 26, 2017 (82 FR 44744). The NPRM was prompted by a report of wire damage on a fuel boost pump power cable, and a separate report of a fuel tank explosion on a similarly equipped airplane. The NPRM proposed to require the installation of new shielded wire bundles and convoluted liners within fuel tank conduits, and revision of the maintenance or inspection program, as applicable, to incorporate certain AWLs. We are issuing this AD to prevent electrical arcing between the fuel boost pump power cable wiring and the surrounding conduit, which could lead to arc-through of the conduit, consequent fire or explosion of the fuel tank, and subsequent loss of the airplane. This AD is further rulemaking following the interim action of AD 2007-24-02, Amendment 39-15268 (72 FR 65446, November 21, 2007) (``AD 2007-24-02''), which applies to all Boeing Model 737-100, -200, -200C, -300, -400, -500 series airplanes. AD 2007-24-02 was prompted by reports of a fuel tank explosion on a Boeing Model 727-200F airplane and chafed wires and a damaged wiring sleeve on a fuel boost pump power cable in a Boeing Model 737-300 airplane. AD 2007-24-02 requires repetitive detailed inspections for damage of the electrical wire and sleeve that run to the fuel boost pump through a conduit in the fuel tank, to address potential electrical arcing between the wiring and the surrounding conduit that could result in arc-through of the conduit, consequent fire or explosion of the fuel tank, and subsequent loss of the airplane. The preamble to AD 2007-24-02 explains that its requirements are considered ``interim action'' and that we might consider further rulemaking. We now have determined that further rulemaking is necessary, and this AD follows from that determination. Comments We gave the public the opportunity to participate in developing this final rule. 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 (ALPA) and The Boeing Company concurred with the proposed AD. Request To Not Require Replacement or To Extend Compliance Time The commenter, Hannes Merrick, requested that the FAA consider not requiring wire bundle replacement if faults are not found during inspection of the affected wire bundles, or at a minimum to extend the compliance time to allow for more time to accomplish the replacement required by the proposed AD. We infer that the commenter would regard the existing repetitive inspections as adequate for maintaining an acceptable level of safety with the current wire bundle configuration. The commenter did not provide substantiating data for extending the compliance time. We do not agree with the commenter's requests. Our experience has shown that these specific wiring design changes are more effective than repetitive inspections in preventing unsafe conditions. The design change required by this AD adds an extra protective layer that is necessary to prevent wire chafing in specific areas of the airplane that are identified in Boeing Alert Service Bulletin 737-28A1273, Revision 1, dated March 14, 2017. We have also determined that the compliance time specified in this AD is appropriate to address the unsafe condition described in this AD. However, under the provisions of paragraph (l) of this AD, we will consider requests for approval of an extension of the compliance time if sufficient data are submitted to substantiate that the change would provide an acceptable level of safety. We have not changed this AD in this regard. Effects of Winglets on Accomplishment of the Proposed Actions Aviation Partners Boeing stated that the installation of winglets per supplemental type certificate (STC) ST01219SE does not affect the accomplishment of the manufacturer's service instructions. We agree with the commenter that STC ST01219SE does not affect the accomplishment of the manufacturer's service instructions. Therefore, the installation of STC ST01219SE does not affect the ability to accomplish the actions required by this AD. We have not changed this AD in this regard. New Service Information In paragraph (h) of the proposed AD we referred to Boeing 737-100/ 200/200C/300/400/500 Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D6-38278-CMR, dated May 2016, as an appropriate source of service information for incorporating certain airworthiness limitations. After the NPRM was issued, we reviewed Boeing 737-100/200/200C/300/400/500 Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D6-38278-CMR, dated November 2017, which also contains the airworthiness limitations cited in this AD. The November 2017 document includes a change to airworthiness limitation 28-AWL-29, which is not one of the airworthiness limitations cited in this AD. We have revised paragraph (h) of this AD to also refer to Boeing 737-100/200/200C/300/400/500 Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D6-38278-CMR, dated November 2017, as an appropriate source of service information for incorporating the airworthiness limitations cited in this AD. Conclusion We reviewed the relevant data, considered the comments 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: [[Page 9180]]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. Related Service Information Under 1 CFR Part 51 We reviewed the following service information. Boeing Alert Service Bulletin 737-28A1273, Revision 1, dated March 14, 2017. This service information describes procedures for the installation of new shielded wire bundles and convoluted liners within fuel tank conduits. Boeing 737-100/200/200C/300/400/500 Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D6-38278-CMR, dated May 2016 and November 2017. This service information describes new AWLs for inspecting the fuel tank wiring and conduits. These documents are distinct since the November 2017 document includes a change to airworthiness limitation 28-AWL-29 (which is not required by this AD). 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 499 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Installation.......................... 154 work-hours x $85 per $5,561 $18,651 $9,306,849 hour = $13,090. Incorporation of Airworthiness 1 work-hour x $85 per 0 85 42,415 Limitations. hour = $85. ---------------------------------------------------------------------------------------------------------------- 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 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 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 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.
