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.

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.

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 List of Subjects in 14 CFR Part 39 15:17 Jul 06, 2010 Jkt 220001 Fleet cost 4 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.

ACTION: Notice of proposed rulemaking (NPRM). 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.

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 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 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 August 23, 2010.

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

[[Page 38946]]

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 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 777-23-0175, 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.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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.

Alternative Methods of Compliance (AMOCs)

    (i)(1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. Send information to 
ATTN: Joe Salameh, Aerospace Engineer, Systems and Equipment Branch, 
ANM-130S, FAA, Seattle Aircraft Certification Office, 1601 Lind 
Avenue, SW., Renton, Washington 98057-3356; telephone (425) 917-
6454; fax (425) 917-6590. Information may be e-mailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) To request a different method of compliance or a different 
compliance time for this AD, follow the procedures in 14 CFR 39.19. 
Before using any approved AMOC on any airplane to which the AMOC 
applies, notify your principal maintenance inspector (PMI) or 
principal avionics inspector (PAI), as appropriate, or lacking a 
principal inspector, your local Flight Standards District Office. 
The AMOC approval letter must specifically reference this AD.

    Issued in Renton, Washington, on June 29, 2010.
Ali Bahrami,
Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
