Airworthiness Directives; The Boeing 

Company 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA withdraws a notice 

of proposed rulemaking (NPRM) that 

proposed a new airworthiness directive 

(AD) for certain The Boeing Company 

Model 777–200 series airplanes. The 

proposed AD would have required 

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. This 

proposed AD would also have required 

installing a new cabin system control 

panel (CSCP); installing a new cabin 

management system (CMS) 

configuration database; and installing 

new operational program software (OPS) 

for the CSCP, zone management unit 

(ZMU), passenger address controller, 

cabin interphone controller, cabin area 

control panel (CACP), speaker drive 

module, overhead electronics units, and 

seat electronics unit. Since the proposed 

AD was issued, we have received new 

data that indicates the unsafe condition 

would not be adequately addressed by 

the proposed action. Subsequently, we 

are considering issuing new rulemaking 

that positively addresses the unsafe 

condition identified in the NPRM and 

eliminates the need for the actions 

proposed in the NPRM. Accordingly, 

the proposed AD is withdrawn. 

ADDRESSES: You may examine the AD 

docket on the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains this AD action, the 

regulatory evaluation, any comments 

received, and other information. The

SUPPLEMENTARY INFORMATION: 

Discussion 

We proposed to amend part 39 of the 

Federal Aviation Regulations (14 CFR 

part 39) with a notice of proposed 

rulemaking (NPRM) for a new AD for 

certain Model 777–200 series airplanes. 

That NPRM published in the Federal 

Register on February 1, 2011 (76 FR 

5505). The NPRM would have required 

installing a new circuit breaker, relays, 

and wiring to allow the flightcrew to 

turn off electrical power to the IFE 

systems and other non-essential 

electrical systems through a switch in 

the flight compartment, and doing other 

specified actions. The actions included 

removing the CSCP core partition 

software, the CACP OPS, the 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). That NPRM would also 

have required installing a new CSCP; 

installing a new CMS CDB, installing 

passenger address controller, cabin

Federal Register / Vol. 78, No. 77 / Monday, April 22, 2013 / Proposed Rules 23691 

interphone controller, speaker drive 

module, overhead electronics units, and 

seat electronics unit. The NPRM 

resulted from an IFE systems review. 

The proposed actions were intended 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 nonnormal or emergency situation. 

Actions Since NPRM (76 FR 5505, 

February 1, 2011) Was Issued 

Since we issued the NPRM (76 FR 

5505, February 1, 2011), we have 

received new data that indicates the 

unsafe condition would not be 

adequately addressed by the proposed 

action. Subsequently, we are 

considering issuing new rulemaking 

that positively addresses the unsafe 

condition identified in the NPRM and 

eliminates the need for the actions 

proposed in the NPRM. 

FAA’s Conclusions 

Upon further consideration, we have 

determined that the unsafe condition 

still exists, however, we intend to 

address it with new AD rulemaking. 

Accordingly, the NPRM (76 FR 5505, 

February 1, 2011) is withdrawn. 

Withdrawal of the NPRM (76 FR 5505, 

February 1, 2011) does not preclude the 

FAA from issuing another related action 

or commit the FAA to any course of 

action in the future. 

Regulatory Impact 

Since this action only withdraws an 

NPRM (76 FR 5505, February 1, 2011), 

it is neither a proposed nor a final rule 

and therefore is not covered under 

Executive Order 12866, the Regulatory 

Flexibility Act, or DOT Regulatory 

Policies and Procedures (44 FR 11034, 

February 26, 1979). 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Withdrawal 

Accordingly, we withdraw the NPRM, 

Docket No. FAA–2011–0034, Directorate 

Identifier 2010–NM–021–AD, which 

published in the Federal Register on 

February 1, 2011 (76 FR 5505). 

Issued in Renton, Washington, on February 

1, 2013.

and wiring to allow the flightcrew to 

turn off electrical power to the IFE 

systems and other non-essential 

electrical systems through a switch in 

the flight compartment, and doing other

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. That NPRM would also 

have required changing the wiring at the 

cabin management system in the purser 

station. The NPRM resulted from an IFE 

systems review. The proposed actions 

were intended to ensure that the 

flightcrew is able to turn off electrical
