Airworthiness Directives; the Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain the Boeing Company Model 777-200 series airplanes. This 
proposed 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 proposed AD would 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 electrical 
load management system (ELMS) panels. We are proposing 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 a switch 
in the flight compartment 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: We must receive comments on this proposed AD by September 3, 
2013.

Discussion

    We have received reports of smoke or flames in the passenger cabin 
of various transport category airplanes (the Boeing Company Model MD-11 
and DC-9 airplanes and Lockheed Martin Corporation/Lockheed Martin 
Aeronautics Company Model L-1011 series airplanes), related to the 
wiring for the passenger cabin IFE system, cabin lighting, and 
passenger seats. In response to these reports of smoke or flames in the 
passenger cabin of various models of transport category airplanes, we 
conducted a comprehensive IFE systems review.
    The systems review determined that, in order to minimize the risk 
of smoke or flames in the passenger cabin, a switch is needed in the 
flight compartment to enable the flightcrew to turn off electrical 
power to the IFE system and other non-essential electrical systems. In 
the event of smoke or flames in the airplane flight deck or passenger 
cabin, the flightcrew's inability to turn off 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.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.
    The phrase ``related investigative actions'' might be used in this 
proposed AD. ``Related investigative actions'' are follow-on actions 
that (1) are related to the primary action, and (2) are actions that 
further investigate the nature of any condition found. Related 
investigative actions in an AD could include, for example, inspections.
    In addition, the phrase ``corrective actions'' might be used in 
this proposed AD. ``Corrective actions'' are actions that correct or 
address any condition found. Corrective actions in an AD could include, 
for example, repairs.

Costs of Compliance

    We estimate that this proposed AD affects 49 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.
