AD 2014-16-11

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200 series airplanes. This AD was prompted by reports of smoke or flames in the passenger cabin of various transport category airplanes related to the wiring for the passenger cabin in-flight entertainment (IFE) system, cabin lighting, and passenger seats. This AD requires, for certain airplanes, doing an inspection of the electrical power control panel for a certain part number, and corrective action if necessary; and, for certain other airplanes, installing a new electrical power control panel, and making changes to the wiring and certain electrical load management system (ELMS) panels. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE systems and other non- essential electrical systems through one or two switches in the flight deck in the event of smoke or flames. In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew's inability to turn off electrical power to the IFE system and other non- essential electrical systems could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non-normal or emergency situation, and consequent loss of control of the airplane.

Final rule.

Discussion \n\n\n\tWe 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 777-200 series airplanes. The NPRM published in the Federal Register on July 17, 2013 (78 FR 42727). The NPRM was prompted by reports of smoke or flames in the passenger cabin of various transport category airplanes, related to the wiring for the passenger cabin IFE system, cabin lighting, and passenger seats. The NPRM proposed to require, for certain airplanes, doing an inspection of the electrical power control panel for a certain part number, and corrective action if necessary; and, for certain other airplanes, installing a new electrical power control panel, and making changes to the wiring and certain ELMS panels. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to the IFE systems and other non-essential electrical systems through one or two switches inthe flight deck in the event of smoke or flames. In the event of smoke or flames in the airplane flight deck or passenger cabin, the flightcrew's inability to turn off electrical power to the IFE system and other non-essential electrical systems could result in the inability to control smoke or flames in the airplane flight deck or passenger cabin during a non-normal or emergency situation, and consequent loss of control of the airplane. \n\nComments \n\n\n\tWe gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (78 FR 42727, July 17, 2013) and the FAA's response to each comment. \n\nSupport for the NPRM (78 FR 42727, July 17, 2013) \n\n\n\tUnited Airlines (UA) supported the NPRM (78 FR 42727, July 17, 2013). \n\nRequest To Accept Modification Deviations Proposed by Japan Airlines (JAL) \n\n\n\tJapan Airlines (JAL) requested that we accept modification deviations proposed by JAL. JAL stated that there were problems with the repair kits including short electrical wire and missing wires. JAL proposed various deviations from the service bulletin instructions in order to address these problems. \n\tWe disagree with the request to accept modification deviations. The issues that JAL experienced with the Boeing kit may not be applicable to other operators; therefore, we are not changing this final rule in this regard. Operators may, however, request approval of an alternative method of compliance (AMOC) for deviations for the Boeing repair kit in accordance with paragraph (k) of this AD. \n\n((Page 48966)) \n\nRequest To Use Alternative Service Information \n\n\n\tJAL requested that we allow the use of Boeing Service Bulletin 777- 23-0254 to load an alternative version of cabin management system (CMS) software. JAL stated that the NPRM (78 FR 42727, July 17, 2013), would require loading the CMS software in accordance with Boeing Service Bulletin 777-23-0176, Revision 2, dated October 26, 2006, as aconcurrent requirement to Boeing Service Bulletin 777-23-0254. JAL stated that it has loaded this required software, but also loaded another version of the software for a cabin configuration change using Boeing Service Bulletin 777-23-0254. JAL stated that Boeing Service Bulletin 777-23-0254 identifies Boeing Service Bulletin 777-23-0176, Revision 2, dated October 26, 2006, as a concurrent requirement; JAL therefore requested that we include Boeing Service Bulletin 777-23-0254 in the NPRM. \n\tWe disagree with the request to use Boeing Service Bulletin 777-23- 0254 to load an alternative version of CMS software. Although Boeing Service Bulletin 777-23-0254 identifies Boeing Service Bulletin 777-23- 0176, Revision 2, dated October 26, 2006, as a concurrent requirement, we have not evaluated the alternative software to ensure it provides an acceptable level of safety to the AD requirements. Operators may request approval of an AMOC for installation of this alternative CMS software in accordance with paragraph (k) of this AD. \n\nRequest To Add New Optional Action \n\n\n\tBoeing and JAL requested that we revise the Costs of Compliance section and paragraph (i)(2) of the NPRM (78 FR 42727, July 17, 2013) to add Boeing Service Bulletin 777-28A0039, Revision 2, dated September 20, 2010, as an option to Boeing Service Bulletin 777-24-0077, Revision 4, dated October 17, 2012, for installation of additional ELMS software. \n\tThe commenters stated that the new ELMS software is required for compliance to another AD (AD 2011-09-15, Amendment 39-16677 (76 FR 24345, May 2, 2011)). The commenters stated that AD 2011-09-15 requires installing new panels in the main equipment center and installing new ELMS software in accordance with Boeing Service Bulletin 777-28A0037, Revision 2, dated September 20, 2010, in order to prevent potential ignition sources inside fuel tanks. The commenters also stated that AD 2011-09-15 identifies Boeing Service Bulletin 777-28A0039, Revision 2, dated September 20, 2010, as an additional source of guidance for installing ELMS software. \n\tBoeing and JAL stated that requiring ELMS software to be installed according to Boeing Service Bulletin 777-24-0087, Revision 2, dated August 16, 2007, as proposed in the NPRM (78 FR 42727, July 17, 2013), will create a conflict with the requirements of AD 2011-09-15, Amendment 39-16677 (76 FR 24345, May 2, 2011). Boeing stated that it intends to revise Service Bulletin 777-24-0077 to Revision 5 to include Boeing Service Bulletin 777-28A0039, Revision 2, dated September 20, 2010, as concurrent service information. \n\tWe agree to add an option to use Boeing Service Bulletin 777- 28A0039, Revision 2, dated September 20, 2010, for installation of additional ELMS software. We have added this reference to the Costs of Compliance section and to paragraph (i)(2) of this final rule, as requested. \n\nChange to Final Rule \n\n\n\tFor editorial purposes, we have moved the credit service bulletin references fromparagraph (j)(3) of the NPRM (78 FR 42727, July 17, 2013) to new paragraphs (j)(3)(i) through (j)(3)(v) of this final rule. \n\nConclusion \n\n\n\tWe 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: \n\t(Agr)re consistent with the intent that was proposed in the NPRM (78 FR 42727, July 17, 2013) for correcting the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM (78 FR 42727, July 17, 2013). \n\tWe also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. \n\nCosts of Compliance \n\n\n\tWe estimate that this AD affects 49 airplanes of U.S. registry. \n\tWe estimate the following costs to comply with this AD: \n\n\n\tEstimated Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost on U.S. \n\tAction Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection/installation and Up to 28 work- $1,436 Up to $3,816.......... Up to $186,984. \n\tchanges. hours x $85 per \n\thour = $2,380. Concurrent installation (Boeing 2 work-hours x $85 0 $170.................. $8,330. \n\tService Bulletin 777-23-0176, per hour = $170. \n\tRevision 2, dated October 26, \n\t2006). Concurrent installation (Boeing 3 work-hours x $85 0 $255.................. $12,495. \n\tService Bulletin 777-24-0077, per hour = $255. \n\tRevision 4, dated October 17, \n\t2012; Boeing Service Bulletin \n\t777-24-0087, Revision 2, dated \n\tAugust 16, 2007; or Boeing \n\tService Bulletin 777-28A0039, \n\tRevision 2, dated September \n\t20, 2010). ---------------------------------------------------------------------------------------------------------------- \n\n\n\tWe estimate the following costs to do any necessary change that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need this replacement: \n\n((Page 48967)) \n\n\n\n\n\n\n\tOn-Condition Costs ---------------------------------------------------------------------------------------------------------------- \n\tCost per \n\tAction Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Change part number........................... 1 work-hour x $85 per hour = $0 $85 \n\t$85. ---------------------------------------------------------------------------------------------------------------- \n\nAuthority forThis Rulemaking \n\n\n\tTitle 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. \n\tWe 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. \n\nRegulatory Findings \n\n\n\tThis 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, \n\t(2) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), \n\t(3) Will not affect intrastate aviation in Alaska, and \n\t(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. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
