Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule.

SUMMARY:

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.

DATES:

This AD is effective September 23, 2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 23, 2014.

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 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 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.

Comments

We 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.

Support for the NPRM (78 FR 42727, July 17, 2013)

United Airlines (UA) supported the NPRM (78 FR 42727, July 17, 2013).

Request To Accept Modification Deviations Proposed by Japan Airlines (JAL)

Japan 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.

We 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.Start Printed Page 48966

Request To Use Alternative Service Information

JAL 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 a concurrent 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.

We 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.

Request To Add New Optional Action

Boeing 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.

The 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.

Boeing 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.

We 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.

Change to Final Rule

For editorial purposes, we have moved the credit service bulletin references from paragraph (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.

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:

  • Αre consistent with the intent that was proposed in the NPRM (78 FR 42727, July 17, 2013) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 42727, July 17, 2013).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Costs of Compliance

We estimate that this AD affects 49 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

ActionLabor costParts costCost per productCost on U.S. operators
Inspection/installation and changesUp to 28 work-hours × $85 per hour = $2,380$1,436Up to $3,816Up to $186,984.
Concurrent installation (Boeing Service Bulletin 777-23-0176, Revision 2, dated October 26, 2006)2 work-hours × $85 per hour = $1700$170$8,330.
Concurrent installation (Boeing Service Bulletin 777-24-0077, Revision 4, dated October 17, 2012; Boeing Service Bulletin 777-24-0087, Revision 2, dated August 16, 2007; or Boeing Service Bulletin 777-28A0039, Revision 2, dated September 20, 2010)3 work-hours × $85 per hour = $2550$255$12,495.

We 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:Start Printed Page 48967

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

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.
