[FR Doc. 2011–1937 Filed 1–31–11; 8:45 am] BILLING CODE 3510–24–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2011–0033; Directorate Identifier 2010–NM–019–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Model 777–200 Series Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Model 777–200 series airplanes. This proposed AD would require installing a new circuit breaker, relays, and wiring to allow the flightcrew to turn off electrical power to the in-flight entertainment (IFE) systems and other non-essential electrical systems through a switch in the flight compartment, and doing other specified actions. The actions include replacing the cabin area control panels; changing the wiring; modifying the purser station or the mstockstill on DSKH9S0YB1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 18:23 Jan 31, 2011 Jkt 223001 A–4 galley, as applicable; installing new cabin system management unit, cabin area control panel, overhead electronics unit, and zone management units operational software, as applicable; and making a change to the cabin services system (CSS) configuration database and installing the new database in the CSS components. This proposed AD would also require changing the wiring at the cabin management system in the purser station. This proposed AD results from an 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. The flightcrew’s inability to turn off electrical power to the IFE system and other non-essential electrical systems in the event of smoke or flames 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 was from cabin IFE system components, including electronic seat boxes mounted under passenger seats, IFE wiring, 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. The flightcrew’s inability to turn off power E:\FR\FM\01FEP1.SGM 01FEP1 5504 Federal Register / Vol. 76, No. 21 / Tuesday, February 1, 2011 / Proposed Rules 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 777–23–0142, dated November 25, 2003. This service bulletin describes procedures for the following actions: • Removing the cabin area control panels. • Changing the wiring. • Installing new cabin control panels. • Modifying the purser station and the A–4 galley, as applicable. • Installing cabin system management unit operational program software. • Installing cabin area control panel operational program software. • Installing zone management unit operational program software. • Installing overhead electronics unit operational program software, if necessary. • Making changes to the new configuration database. • Installing the new configuration database to the cabin services system. Boeing Service Bulletin 777–23–0142, dated November 25, 2003 refers to Jamco Service Letter SL–K0789, dated June 10, 1997, as an additional source of service information for modifying the cabin system control panel compartment for airplanes in Group 4 (as identified in Boeing Service Bulletin 777–23–0142, dated November 25, 2003). Boeing Service Bulletin 777–23–0142, dated November 25, 2003, specifies prior or concurrent accomplishment of Boeing Service Bulletin 777–23–0057, dated April 9, 1998, which describes procedures for changing the wiring in the purser station for airplanes in Group 4 (as identified in Boeing Service Bulletin 777–23–0142, dated November 25, 2003). Difference Between Service Information and AD Boeing Service Bulletin 777–23–0142, dated November 25, 2003, does not contain a compliance time for the required actions. This NPRM would require the actions be done within 60 months after the effective date of this AD. We have coordinated this difference with The Boeing Company. 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 the same type design. This proposed AD would require accomplishing the actions specified in the service information described previously. Costs of Compliance Currently, there are no affected airplanes on the U.S. Register. The following table provides the estimated costs for U.S. operators to comply with this proposed AD if an affected airplane is imported and placed on the U.S. Register in the future.

According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 VerDate Mar<15>2010 Parts 18:23 Jan 31, 2011 Jkt 223001 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. 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 List of Subjects in 14 CFR Part 39 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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; The Boeing Company Model 777-200 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 series airplanes. This proposed AD would require 
installing a new circuit breaker, relays, and wiring to allow the 
flightcrew to turn off electrical power to the in-flight entertainment 
(IFE) systems and other non-essential electrical systems through a 
switch in the flight compartment, and doing other specified actions. 
The actions include replacing the cabin area control panels; changing 
the wiring; modifying the purser station or the A-4 galley, as 
applicable; installing new cabin system management unit, cabin area 
control panel, overhead electronics unit, and zone management units 
operational software, as applicable; and making a change to the cabin 
services system (CSS) configuration database and installing the new 
database in the CSS components. This proposed AD would also require 
changing the wiring at the cabin management system in the purser 
station. This proposed AD results from an 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. The flightcrew's inability to turn off electrical 
power to the IFE system and other non-essential electrical systems in 
the event of smoke or flames 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 was from cabin IFE system components, including electronic 
seat boxes mounted under passenger seats, IFE wiring, 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. The flightcrew's inability to turn off 
power

[[Page 5504]]

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 777-23-0142, dated 
November 25, 2003. This service bulletin describes procedures for the 
following actions:
     Removing the cabin area control panels.
     Changing the wiring.
     Installing new cabin control panels.
     Modifying the purser station and the A-4 galley, as 
applicable.
     Installing cabin system management unit operational 
program software.
     Installing cabin area control panel operational program 
software.
     Installing zone management unit operational program 
software.
     Installing overhead electronics unit operational program 
software, if necessary.
     Making changes to the new configuration database.
     Installing the new configuration database to the cabin 
services system.
    Boeing Service Bulletin 777-23-0142, dated November 25, 2003 refers 
to Jamco Service Letter SL-K0789, dated June 10, 1997, as an additional 
source of service information for modifying the cabin system control 
panel compartment for airplanes in Group 4 (as identified in Boeing 
Service Bulletin 777-23-0142, dated November 25, 2003).
    Boeing Service Bulletin 777-23-0142, dated November 25, 2003, 
specifies prior or concurrent accomplishment of Boeing Service Bulletin 
777-23-0057, dated April 9, 1998, which describes procedures for 
changing the wiring in the purser station for airplanes in Group 4 (as 
identified in Boeing Service Bulletin 777-23-0142, dated November 25, 
2003).

Difference Between Service Information and AD

    Boeing Service Bulletin 777-23-0142, dated November 25, 2003, does 
not contain a compliance time for the required actions. This NPRM would 
require the actions be done within 60 months after the effective date 
of this AD. We have coordinated this difference with The Boeing 
Company.

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 the same type design. 
This proposed AD would require accomplishing the actions specified in 
the service information described previously.

Costs of Compliance

    Currently, there are no affected airplanes on the U.S. Register. 
The following table provides the estimated costs for U.S. operators to 
comply with this proposed AD if an affected airplane is imported and 
placed on the U.S. Register in the future.

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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:


[[Page 5505]]


The Boeing Company: Docket No. FAA-2011-0033; Directorate Identifier 
2010-NM-019-AD.

Comments Due Date

    (a) We must receive comments by March 18, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to The Boeing Company Model 777-200 series 
airplanes, certificated in any category; as identified in Boeing 
Service Bulletin 777-23-0142, dated November 25, 2003.

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 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. The flightcrew's 
inability to turn off electrical power to the IFE system and other 
non-essential electrical systems in the event of smoke or flames 
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 cabin area control panels; change the wiring; install new cabin 
area control panels; modify the purser station or A-4 galley, as 
applicable; install new cabin system management unit, cabin area 
control panel, overhead electronics unit, and zone management units 
operational software, as applicable; and make a change to the cabin 
services system (CSS) configuration database and install the new 
database in the CSS components; in accordance with the 
Accomplishment Instructions of Boeing Service Bulletin 777-23-0142, 
dated November 25, 2003.

    Note 1:  Boeing Service Bulletin 777-23-0142, dated November 25, 
2003, refers to Jamco Service Letter SL-K0789, dated June 10, 1997, 
as an additional source of guidance for modification of the cabin 
system control panel compartment for airplanes in Group 4 (as 
identified in Boeing Service Bulletin 777-23-0142, dated November 
25, 2003).

Concurrent Requirement

    (h) For Group 4 airplanes identified in Boeing Service Bulletin 
777-23-0142, dated November 25, 2003: Prior to or concurrently with 
accomplishing the requirements of paragraph (g) of this AD, change 
the termination of two wires at the cabin management terminal in the 
purser station, in accordance with Boeing Service Bulletin 777-23-
0057, dated April 9, 1998.
