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 removing the cabin 

system control panel (CSCP) core 

partition software, the cabin area control 

panel (CACP) operational program 

software (OPS), the zone management 

units (ZMU) OPS, and the cabin system 

management unit (CSMU) OPS; 

installing OPS for the CSCP, CACP, 

ZMU, and CSMU; and installing the 

new configuration database (CDB). This 

proposed AD would also require 

installing a new CSCP; installing a new 

cabin management system (CMS) CDB; 

and installing new OPS for the CSCP, 

ZMU, passenger address controller, 

cabin interphone controller, CACP, 

speaker drive module, overhead 

electronics units, and seat electronics 

unit. 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. 

DATES: We must receive comments on 

this proposed AD by March 18, 2011.

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. 

The flightcrew’s inability to turn off 

power to the IFE system and other nonessential electrical systems in the event 

of smoke or flames, if not corrected, 

could result in the inability to control 

smoke or flames in the airplane flight 

deck or passenger cabin during a nonnormal or emergency situation. 

Relevant Service Information 

We have reviewed Boeing Service 

Bulletin 777–23–0176, Revision 2, dated 

October 26, 2006. This service bulletin 

describes procedures for the following 

actions: 

• Removing the cabin system control 

panel (CSCP) core partition (CP) 

software, the cabin area control panel 

(CACP) operational program software 

(OPS), the zone management unit 

(ZMU) OPS, and the cabin system 

management unit (CSMU) OPS. 

• Installing CSCP–CP software. 

• Installing CACP OPS software. 

• Installing ZMU OPS software. 

• Installing CSMU OPS software. 

• Installing the new configuration 

database in the cabin management 

system (CMS) line replaceable units. 

Boeing Service Bulletin 777–23–0176, 

Revision 2, dated October 26, 2006, 

specifies prior or concurrent 

accomplishment of Boeing Service 

Bulletin 777–23–0141, dated June 14, 

2001, which describes procedures for 

replacing the OPS for the CSCP, the 

CACP, and the CSMU, and reinstalling 

the configuration database. 

Boeing Service Bulletin 777–23–0176, 

Revision 2, dated October 26, 2006, also 

specifies prior or concurrent 

accomplishment of Boeing Service 

Bulletin 777–23–0010, dated April 25, 

1996, which describes procedures for 

installing a new CSCP; a new CMS 

configuration database; and new OPS 

for the CSCP, ZMU, passenger address 

controller, cabin interphone controller, 

CACP, speaker drive module, overhead 

electronics unit, and seat electronics 

unit. 

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, except as 

discussed under ‘‘Differences Between 

the Proposed AD and Service 

Information.’’ 

Difference Between the Proposed AD 

and Service Information 

Boeing Service Bulletin 777–23–0176, 

Revision 2, dated October 26, 2006, does 

not contain a compliance time for the 

proposed modification specified in 

paragraph (g) of this NPRM. This NPRM 

proposes a compliance time of 60 

months. This difference has been 

coordinated with The Boeing Company. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 47 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 

mstockstill on DSKH9S0YB1PROD with PROPOSALS

Federal Register / Vol. 76, No. 21 / Tuesday, February 1, 2011 / Proposed Rules 5507 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

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: 

Airbus, in the frame of the Extended 

Service Goal (ESG) exercise, has 

demonstrated by post-certification analysis 

that, among the types of yokes in service, one 

component on the CF6–80C2 forward engine 

mounts (skinny cast yoke) does not meet the 

Design Service Goal (DSG) requirements. 

This condition, if not corrected, could 

result in a deterioration of the structural 

integrity of the forward engine mount. 

* * * * * 

The unsafe condition is possible 

separation of the engine from the engine 

mount during flight. The proposed AD 

would require actions that are intended 

to address the unsafe condition 

described in the MCAI.
