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 The Boeing Company Model 787-8 and 787-9 airplanes. The NPRM published in the 
                    **Federal Register**
                     on November 17, 2017 (82 FR 54302). The NPRM was prompted by reports of failures of the CAC inlet ice protection system (CIPS) inlet lip heater assemblies due to chafing of the CIPS inlet lip heater wire harness against adjacent structures. The NPRM proposed to require changing the airplane electrical connectors and the routes of certain wire bundles, and installing new or modified left and right CAC inlet duct assemblies. We are issuing this AD to address any damage to the CIPS inlet lip heater wire bundle, which could cause an electrical short and potential loss of functions essential for safe flight of the airplane. 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. Request for Clarification of Affected Spare Parts Oman Air requested clarification regarding whether the proposed AD applies only to the airplane line numbers specified in the service information, or whether the proposed AD would also require modification of spare ducts. Oman Air stated that the applicability in the proposed AD includes those airplanes that are specified in Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 001, dated March 22, 2017. Oman Air also stated that the service information also affects spare CAC inlet duct assemblies with part numbers specified in the service information. Oman Air commented that the service information recommended that the spares be modified in accordance with Boeing Alert Service Bulletin B787-81205-SB300019-00, or any later FAA-approved revision. Oman Air stated that there is no mention of spares in the proposed rule, no compliance time associated with the spares, and no parts installation prohibition paragraph. We agree to clarify. This AD applies only to the airplanes specified in the applicability, which includes Boeing Model 787-8 and 787-9 airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 002, dated April 20, 2018. Modification of spare parts is not required by this AD because operators must maintain affected airplanes in the required configuration. The FAA is not mandating action on spare parts, but an operator that wants to use those parts and not discard them must do the modification using the component service information. In addition, the existing spare parts cannot be installed after the accomplishment of Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 001, dated March 22, 2017, because the electrical connectors are different due to the modifications in the component service information and the airplane service information. We have not changed this AD in this regard. 
 
 Request To Use the Information Notice All Nippon Airways (ANA), Boeing, and United Airlines (UAL) requested that the FAA use Boeing Information Notice B787-A-30-00-0019-02A-931E-D, Issue 001, dated December 15, 2017, as a source when referencing Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 001, dated March 22, 2017. Boeing stated that the information notice informs operators of a wire termination reference error that does not affect system function or airplane safety. ANA stated that the correction in the information notice must be incorporated in conjunction with the incorporation of Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 001, dated March 22, 2017. UAL stated that the use of the information notice would avoid unnecessary requests for alternative methods of compliance (AMOC). We agree with the commenters. We agree that the information notice corrects a wiring termination reference error for certain configurations to make it consistent with the 787 Wiring Diagram Manual and that accomplishing the service information with the wiring error does not affect system function or airplane safety. The manufacturer has revised the service information to correct the wiring termination reference error; therefore, we have revised paragraph (g) of this AD to require accomplishment of the actions in accordance with Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 002, dated April 20, 2018. We have also added paragraph (h) to this AD to give credit for actions completed before the effective date of this AD using Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 001, dated March 22, 2017. In addition, we have given credit for Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 001, dated March 22, 2017, in conjunction with Boeing Information Notice B787-A-30-00-0019-02A-931E-D, Issue 001, dated December 15, 2017. We redesignated subsequent paragraphs accordingly. 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 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 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 We reviewed Boeing Alert Service Bulletin B787-81205-SB300019-00, Issue 002, dated April 20, 2018. This service information describes procedures for changing the airplane electrical connectors and the routes of certain wire bundles, and installing new or modified left and right CAC inlet duct assemblies. 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

 According to the manufacturer, all of the costs of this 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 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 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 and associated appliances 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.
