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 The Boeing Company Model 767-300 series airplanes. This 
proposed AD was prompted by a report that, for certain airplanes, 
reinforcement straps were not bonded to the center overhead stowage 
bins in the passenger compartment. For certain airplanes, this proposed 
AD would require performing an inspection of reinforcement straps to 
ensure they are correctly bonded to the center overhead stowage bins, 
and bonding the reinforcement straps to the center overhead stowage 
bins if necessary. For certain airplanes, this proposed AD would 
require installing reinforcement straps on the center overhead stowage 
bins. We are proposing this AD to prevent missing or incorrectly bonded 
reinforcement straps, which could result in the center overhead stowage 
bins breaking loose and causing injury to passengers and damage to 
equipment during in-flight turbulence.

DATES: We must receive comments on this proposed AD by November 30, 
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-2012-1073; 
Directorate Identifier 2012-NM-078-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 that, for certain airplanes, reinforcement 
straps installed at specified stations for the center overhead stowage 
bins in the passenger compartment were not correctly bonded to the 
stowage bins. In addition, for some airplanes, reinforcement straps may 
have been missing on the center overhead stowage bins at other 
specified stations. This condition, if not corrected, could result in 
the center overhead stowage bins breaking loose and causing injury to 
passengers and damage to equipment during in-flight turbulence.

Relevant Service Information

    We reviewed Boeing Special Attention Service Bulletin 767-25-0520, 
dated February 8, 2012. For certain airplanes, this service bulletin 
describes procedures for general visual and detailed inspections of the 
existing reinforcement straps installed on the center overhead storage 
bins in the passenger compartment to ensure they are bonded to the 
center overhead storage bins. For airplanes on which the straps are 
incorrectly bonded, this service bulletin describes procedures for 
bonding the reinforcement straps to the center overhead stowage bins. 
For certain airplanes, this service bulletin describes procedures for 
installing reinforcement straps.

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 the same type design.

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:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                   Labor cost          Parts cost       Cost per product        operators
----------------------------------------------------------------------------------------------------------------

 General Visual Inspection for     per hour = $170.                                            airplanes).
 Correct Bonding.

 Install Reinforcement Straps.     per hour = $595.                                            airplanes).
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the proposed inspection. We 
have no way of determining the number of aircraft that might need this 
repair:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                 Action                           Labor cost            Parts cost         Cost per product
----------------------------------------------------------------------------------------------------------------

 Center Overhead Stowage Bins.             $595 to $1,020.
----------------------------------------------------------------------------------------------------------------


[[Page 63268]]

    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.
