Unsafe Condition
(e) This AD results from fuel system
reviews conducted by the manufacturer. The
Federal Aviation Administration is issuing
this AD to prevent lightning-induced
transients to the fuel quantity indication
system, which could cause voltage levels to
go beyond original design levels between fuel
tank probes and structure and become a
potential ignition source at the fuel tank,
which, in combination with flammable fuel
vapors, could result in a fuel tank explosion
and consequent loss of the airplane.
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.

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 installing new operational
software in the cabin management
system, and loading new software into
the mass memory card. 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 nonessential 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 August 23, 2010.
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
E:\FR\FM\07JYP1.SGM
07JYP1
38946
Federal Register / Vol. 75, No. 129 / Wednesday, July 7, 2010 / Proposed Rules
was from cabin IFE system components,
including electronic seat boxes mounted
under passenger seats, IFR 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 nonessential 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 777–23–0175, Revision 2, dated
October 12, 2006. The service bulletin
describes procedures for installing new
operational software in the cabin
management system as follows:
• At the cabin system control panel
(CSCP), remove the installed mass
memory card (MMC) 285W0925–1 or
285W0925–2.
• Install the new MMC 285W0925–3.
• Install a new cabin system
management unit (CSMU) software part
number 2313–BCE–01T–03.
• Install a new cabin area control
panel (CACP) software part number
2313–BCE–01U–02.
• Install a new zone management unit
(ZMU) software part number 2374–
BCE–021–02.
• Install a new overhead electronics
unit (OEU) operational software (OPS)
(12 port) part number 2310–BCE–01V–
02, if the airplane configuration has
OEU hardware 285W0029–5 installed.
• Install a new configuration database
(CDB).
• Install the new CDB to the cabin
service system.
Boeing Service Bulletin 777–23–0175,
Revision 2, dated October 12, 2006,
specifies prior or concurrent
accomplishment of Boeing Component
Service Bulletin 285W0925–23–02,
dated July 11, 2002, which describes
procedures for loading the new cabin
services system central storage device
software and CSCP OPS into the MMC.
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
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 59 airplanes of U.S.
registry. The following table provides
the estimated costs for U.S. operators to
comply with this proposed AD.

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.
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This

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.

ACTION: Notice of proposed rulemaking

SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as: Investigation conducted by
Thales on probes revealed oil residue
between the stator and the rotor parts of
the AoA [angle of attack] vane position
resolvers. This oil residue was due to
incorrect cleaning of the machining oil
during the manufacturing process of the
AoA resolvers. At low temperatures,
this oil residue becomes viscous
(typically in cruise) causing lag of AoA
vane movement. Such condition could
lead to discrepant AoA measurement. If
not corrected, and if two or three AoA
probes were simultaneously affected
and provided wrong indications of the
AoA to a similar extent, it could lead to
a late activation of the angle of attack
protection, which in combination with
light at high angle of attack would
constitute an unsafe condition. The
proposed AD would require actions that
are intended to address the unsafe
condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by August 23, 2010.

part number 2313-BCE-01U-02.
Install a new zone management unit (ZMU) software part
number 2374-BCE-021-02.
Install a new overhead electronics unit (OEU) operational
software (OPS) (12 port) part number 2310-BCE-01V-02, if the airplane
configuration has OEU hardware 285W0029-5 installed.
Install a new configuration database (CDB).
Install the new CDB to the cabin service system.
Boeing Service Bulletin 777-23-0175, Revision 2, dated October 12,
2006, specifies prior or concurrent accomplishment of Boeing Component
Service Bulletin 285W0925-23-02, dated July 11, 2002, which describes
procedures for loading the new cabin services system central storage
device software and CSCP OPS into the MMC.
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 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 59 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:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
The Boeing Company: Docket No. FAA-2010-0678; Directorate Identifier
2010-NM-020-AD.
Comments Due Date
(a) We must receive comments by August 23, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to The Boeing Company Model 777-200 and -300
series airplanes, certificated in any category; as
[[Page 38947]]
identified in Boeing Service Bulletin 777-23-0175, Revision 2, dated
October 12, 2006.
Subject
(d) Air Transport Association (ATA) of America Code 23:
Communications.
Unsafe Condition
(e) This AD results from an in-flight entertainment (IFE)
systems review. We are proposing this AD to minimize the risk of
smoke or flames in the passenger cabin by installing a switch 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 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.
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:
Replace the mass memory card (MMC) with a new MMC; install new cabin
system management unit (CSMU) software, cabin area control panel
(CACP) software, and new zone management unit (ZMU) software;
install new overhead electronics unit (OEU) operational program
software, if applicable; install a new configuration database (CDB);
and install the new CDB to the cabin service system; in accordance
with the Accomplishment Instructions of Boeing Service Bulletin 777-
23-0175, Revision 2, dated October 12, 2006.
Concurrent Requirement
(h) Prior to or concurrently with accomplishing the requirements
of paragraph (g) of this AD, load the new cabin services system
central storage device software and cabin system control panel
operational software into the MMC, in accordance with Boeing
Component Service Bulletin 285W0925-23-02, dated July 11, 2002.
