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

[[Page 31853]]

(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:

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.

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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Installation
