2014-12650. 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 certain The Boeing Company Model 777-200 and -300 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 installing wiring and making changes to certain electrical load management system (ELMS) panels and other concurrent requirements to ensure 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 July 8, 2014.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of July 8, 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 and -300 series airplanes. 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 published in the Federal Register on May 10, 2013 (78 FR 27310). The NPRM proposed to require installing wiring and making changes to certain ELMS panels and other concurrent requirements. We are issuing this AD to ensure 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 27310, May 10, 2013) and the FAA's response to each comment. United Airlines and Air Line Pilots Association International (ALPA) supported the NPRM.

Request To Include Additional Work-Hours in Costs of Compliance

American Airlines (AA) requested that we add 200 work-hours to the total labor costs specified in the Costs of Compliance section of the NPRM (78 FR 27310, May 10, 2013). AA stated that the costs of compliance specified in the NPRM include the work-hours specified in Boeing Service Bulletin 777-24-0075, Revision 3, dated August 26, 2010, but those work-hours do not take into account the work-hours for making changes to certain ELMS panels specified in the concurrent service bulletins.

We acknowledge that we underestimated the work-hours for completing the installation of wiring and changing the ELMS panel wiring in the NPRM (78 FR 27310, May 10, 2013). We have added 200 work-hours to the Costs of Compliance of this final rule to account for the work-hours for making changes to certain ELMS panels.

Request To Allow Use of Later Revisions of ELMS Service Information

AA requested that we allow use of later revisions of certain ELMS service information instead of Boeing Service Bulletin 777-24-0075, Revision 3, dated August 26, 2010. AA stated that revised ELMS service information has been released since publication of Boeing Service Bulletin 777-24-0075, Revision 3, dated August 26, 2010.

We do not agree. Allowing a reference to “a later revision” of a specific service document violates Office of the Federal Register policies for approving materials incorporated by reference.

However, we have reviewed Boeing Service Bulletin 777-24-0075, Revision 4, dated January 8, 2014, which contains the appropriate service information. Operators may request approval of an alternative method of compliance (AMOC) under the provisions of paragraph (j) of this final rule to use later revisions of the ELMS service information. We have revised paragraph (g) of this AD to refer to Boeing Service Bulletin 777-24-0075, Revision 4, dated January 8, 2014, as the appropriate source of service information. We have given credit for Boeing Service Bulletin 777-24-0075, Revision 3, dated August 26, 2010, in paragraph (i)(2) of this AD.

Request To Use Equivalent Procedure

AA requested that we allow the use of an operator's equivalent procedure to mark the applicable service bulletin number on the panel, rather than using the labels in the General Electric (GE) kits as specified. AA stated that Boeing Service Bulletin 777-24-0075, Revision 3, dated August 26, 2010, specifies installing a label of the service bulletin number on the ELMS power panels. AA stated that the labels that are in the GE kits have a shelf life that expires prior to the compliance time of 60 months.

We agree that an operator's equivalent procedure may safely and effectively be used to indelibly mark the applicable service bulletin number on the panels in place of the labels. We have revised paragraph (g) of this final rule accordingly. We have also added Note 1 to paragraph (g) of this AD to specify that additional guidance on indelibly marking the panel can be found in Boeing Process Specification BAC5307.

Request To Allow Various Modifications to Repair Kits

Japan Air Lines (JAL) requested that we allow certain modifications of the repair kits, which JAL has proposed to Boeing and Smiths Aerospace Actuation Systems to address problems with the Smiths Aerospace Actuation Systems repair kits. JAL stated that problems with the repair kits include a certain electrical wire being too short, omission of certain other wires, inclusion of unshielded wires rather than shielded wires, inability to install a certain relay bracket, and inclusion of an incorrect relay part number.

We disagree with the request to allow modifications of repair kits in this final rule. Boeing Service Bulletin 777-24-0075, Revision 4, dated January 8, 2014, is the latest service information available for compliance with the actions specified in paragraph (g) of this final rule. We do not consider it appropriate to include various provisions in an AD applicable only to individual airplanes or to a single operator's configuration or use of an airplane. However, any person may request approval of an alternative method of compliance (AMOC) under the provisions of paragraph (j) of this final rule. No change has been made to this final rule in this regard.

Requests To Add Alternative ELMS Software

Boeing requested that we add alternative ELMS software to the NPRM (78 FR 27310, May 10, 2013). Boeing and JAL pointed out that new ELMS software is required in order to be compliant with the requirements of AD 2011-09-15, Amendment 39-16677 (76 FR 24345, May 2, 2011). Boeing and JAL stated that AD 2011-09-15 requires, among other actions, installing new ELMS software. Note 2 of AD 2011-09-15 specifies that Boeing Service Bulletin 777-28A0039, Revision 2, dated September 20, 2010, is an additional source of guidance for installing the new ELMS software. Boeing and JAL stated that, if ELMS software is required to be installed in accordance with Boeing Service Bulletin 777-24-0087, Revision 2, dated August 16, 2007, as proposed in the NPRM, a conflict with the requirements of AD 2011-09-15 will be created.

We agree to allow the option of installing ELMS software using Boeing Service Bulletin 777-28A0039, dated June 13, 2008; Revision 1, dated January 8, 2009; or Revision 2, dated September 20, 2010. We have revised paragraph (h)(5) of this final rule to add a reference to Boeing Service Bulletin 777-28A0039, Revision 2, dated September 20, 2010. We have also revised paragraph (i)(5) of this final rule to provide credit for ELMS software installations done before the effective date of this AD using Boeing Service Bulletin 777-28A0039, dated June 13, 2008; or Revision 1, dated January 8, 2009.

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:

• Are consistent with the intent that was proposed in the NPRM (78 FR 27310, May 10, 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 27310, May 10, 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 59 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Wiring changes	236 work-hours × $85 per hour = $20,060	$2,503	$22,563	$1,331,217
Concurrent ELMS software installation (Boeing Service Bulletin 777-24-0087, Revision 2, dated August 16, 2007; or 777-28A0039, Revision 2, dated September 20, 2010)	3 work-hours × $85 per hour = $255	0	255	15,045
Concurrent operational program software change (Boeing Service Bulletin 777-23-0175, Revision 2, dated October 12, 2006)	4 work-hours × $85 per hour = $340	0	340	20,060
Concurrent power isolation switch installation (Boeing Service Bulletin 777-24-0074, Revision 4, dated September 13, 2012)	5 work-hours × $85 per hour = $425	751	1,176	69,384
Concurrent cabin services system hardware and software change (No affected U.S. operators; Boeing Service Bulletin 777-23-0142, dated November 25, 2003)	10 work-hours × $85 per hour = $850	119,959	120,809	0

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.
