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 and -300 series airplanes. The proposed AD would 
have required removing the electrical system control panel, changing 
the wiring, installing a new electrical power control panel, and 
installing new operational software for the electrical load management 
system and configuration database. 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withdrawn.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 street

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 and -300 series airplanes. That NPRM 
published in the Federal Register on March 8, 2011 (76 FR 12617). The 
NPRM would have required removing the electrical system control panel, 
changing the wiring, installing a new electrical power control panel, 
and installing new operational software for the electrical load 
management system and configuration database. The NPRM resulted from an 
in-flight entertainment (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. 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.

Actions Since NPRM (76 FR 12617, March 8, 2011) Was Issued

    Since we issued the NPRM (76 FR 12617, March 8, 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 12617, March 8, 2011) is 
withdrawn.
    Withdrawal of the NPRM (76 FR 12617, March 8, 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 12617, March 8, 
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

reference, Safety.

The Withdrawal

    Accordingly, we withdraw the NPRM, Docket No. FAA-2011-0153, 
Directorate Identifier 2010-NM-022-AD, which published in the Federal 
Register on March 8, 2011 (76 FR 12617).

    Issued in Renton, Washington, on February 1, 2013.
