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.

date of this AD, install a support bracket and 

coupler on the left and right wing-to-fuselage 

transition, and metallic overbraid on the left 

and right leading edge wire assembly, in 

accordance with the Accomplishment 

Instructions of Boeing Service Bulletin 

DC10–28–262, Revision 1, dated June 9, 

2010. 

Installation According to Previous Issue of 

Service Bulletin 

(h) Installing a support bracket and coupler 

on the left and right wing-to-fuselage 

transition, and metallic overbraid on the left 

and right leading edge wire assembly, is also 

acceptable for compliance with the 

requirements of paragraph (g) of this AD if

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 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.

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 


cprice-sewell on DSK8KYBLC1PROD with PROPOSALS-1
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.

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.

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: 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.
