Airworthiness Directives; The Boeing Company Model 777-200 and -
300 Series 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 Model 777-200 and -300 series airplanes. This proposed AD would
require removing the electrical system control panel, changing the
wiring, installing a new electrical power control panel, and installing
new operational software for the electrical load management system and
configuration database. This proposed AD results from an in-flight
entertainment (IFE) systems review. We are proposing this AD to ensure
that the flightcrew is able to turn off electrical power to the IFE
system 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.
DATES: We must receive comments on this proposed AD by April 22, 2011.
ADDRESSES: You may send comments by any of the following methods:

Discussion
In response to numerous reports of smoke or flames in the passenger
cabin of various models of transport category airplanes, we conducted a
comprehensive in-flight entertainment (IFE) systems review. Earlier
investigation of the reports had revealed that the source of the smoke
and flames was from cabin IFE system components, including electronic
seat boxes mounted under passenger seats, IFE wirings, IFE monitors,
cabin lighting, wall outlets, and other non-essential cabin electrical
systems.
The systems review disclosed 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, if not corrected, 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.
Relevant Service Information
We have reviewed Boeing Service Bulletin 777-24-0074, Revision 1,
dated October 5, 2006. This service bulletin describes procedures for
removing the electrical power control panel, changing the wiring, and
installing a new electrical power control panel having the two new
cabin power control switches.
Boeing Service Bulletin 777-24-0074, Revision 1, dated October 5,
2006, also specifies prior or concurrent accomplishment of Boeing
Service Bulletin 777-24-0070, dated April 4, 2002, which describes
procedures for installing new operational software (OPS) for the
electrical load management system and new configuration database
software.
Boeing Service Bulletin 777-24-0074, Revision 1, dated October 5,
2006, refers to Boeing Component Service Bulletin 233W3202-24-04,
Revision 1, dated September 25, 2003, as an additional source of
guidance for installing the passenger compartment electrical power
isolation switches.
FAA's Determination and Requirements of This Proposed AD
We are proposing this AD because we evaluated all relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same
[[Page 12618]]
type designs. This proposed AD would require accomplishing the actions
specified in the service information described previously.
Costs of Compliance
We estimate that this proposed AD would affect 42 airplanes of U.S.
registry. The following table provides the estimated costs for U.S.
operators 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), and
3. 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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

systems review. We are issuing this AD to ensure that the flightcrew
is able to turn off electrical power to the IFE system 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

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.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Modification
(g) Within 60 months after the effective date of this AD, remove
the electrical power control panel, change the wiring, and install a
new electrical power control panel, in accordance with Boeing
Service Bulletin 777-24-0074, Revision 1, dated October 5, 2006.
Note 1: Boeing Service Bulletin 777-24-0074, Revision 1, dated
October 5, 2006, refers to Boeing Component Service Bulletin
233W3202-24-04, Revision 1, dated September 25, 2003, as an
additional source of guidance for installing the passenger
compartment electrical power isolation switches.
Concurrent Requirements
(h) Prior to or concurrently with accomplishing the requirements
of paragraph (g) of this AD, install the electrical load management
system operational software and configuration database software, in
accordance with the Accomplishment Instructions of Boeing Service
Bulletin 777-24-0070, dated April 4, 2002.
