Discussion We received a report from the manufacturer indicating that the lowered ceiling support structure of Section 41, in airplanes incorporating the OSU option, was found to be understrength when subjected to a 9.0 g forward load. This condition, if not corrected, could cause the forward lowered ceiling panels and support structure to become dislodged during an occurrence of a 9.0 g forward load and consequent injury to personnel or interference with an emergency evacuation. Relevant Service Information We reviewed Boeing Special Attention Service Bulletin 777–25– 0482, dated February 24, 2011. This service information describes procedures for installing new structural members and new tie rod(s) and attach fittings on the left and right sides of the lowered ceiling support structure. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously.

Airworthiness Directives; the Boeing Company 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 Boeing Company Model 777-200, -200LR, and -300ER series 
airplanes. This proposed AD was prompted by a report from the 
manufacturer indicating that the lowered ceiling support structure of 
Section 41, in airplanes incorporating the overhead space utilization 
(OSU) option, was found to be under-strength when subjected to a 9.0 g 
forward load. This proposed AD would require installing new structural 
members in and new tie rod(s) and attach fittings on the left and right 
sides of the lowered ceiling support structure. We are proposing this 
AD to prevent the forward lowered ceiling panels and support structure 
from becoming dislodged during an occurrence of a 9.0 g forward load 
and consequent injury to personnel or interference with an emergency 
evacuation.

DATES: We must receive comments on this proposed AD by January 17, 
2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2011-1257; 
Directorate Identifier 2011-NM-124-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    We received a report from the manufacturer indicating that the 
lowered ceiling support structure of Section 41, in airplanes 
incorporating the OSU option, was found to be under-strength when 
subjected to a 9.0 g forward load. This condition, if not corrected, 
could cause the forward lowered ceiling panels and support structure to 
become dislodged during an occurrence of a 9.0 g forward load and 
consequent injury to personnel or interference with an emergency 
evacuation.

Relevant Service Information

    We reviewed Boeing Special Attention Service Bulletin 777-25-0482, 
dated February 24, 2011. This service information describes procedures 
for installing new structural members and new tie rod(s) and attach 
fittings on the left and right sides of the lowered ceiling support 
structure.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

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

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                      hour = $1,615.
----------------------------------------------------------------------------------------------------------------

    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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

personnel or interference with an emergency evacuation.

(f) Compliance

    Comply with this AD within the compliance times specified,
