Airworthiness Directives; The Boeing Company Model 767-200 and -
300 Series 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 Model 767-200 and 767-300 series airplanes. This proposed AD
would require installing cargo bulkhead supports, ceiling supports,
secondary dam support, drainage tubing, and ceiling panels to the
forward lower lobe in the forward cargo compartment. This proposed AD
was prompted by reports of water accumulation in the forward lower lobe
of the forward cargo compartment. We are proposing this AD to prevent
water from accumulating in the forward lower lobe of the forward cargo
compartment and entering the adjacent electronic equipment bay, which
could result in an electrical short and the potential loss of several
functions essential for safe flight.
DATES: We must receive comments on this proposed AD by November 25,
2011.

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-2011-1063;
Directorate Identifier 2011-NM-080-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
[[Page 62662]]
personal information you provide. We will also post a report
summarizing each substantive verbal contact we receive about this
proposed AD.
Discussion
We received reports of high levels of water accumulation in the
forward lower lobe of the forward cargo compartment and the potential
for water to enter into the electronic equipment bay adjacent to it.
Water coming through the floor panels can accumulate up to 12 gallons
at this location and typical aircraft movement may not remove all the
water. This condition, if not corrected, could result in water
accumulating in the forward lower lobe of the forward cargo compartment
and entering the adjacent electronic equipment bay, which could result
in an electrical short and the potential loss of several functions
essential for safe flight.
Relevant Service Information
We reviewed Boeing Alert Service Bulletin 767-25A0505, Original
Issue, dated January 14, 2011. The service information describes
procedures for the installing cargo bulkhead supports, right-side
ceiling supports, left-side ceiling supports, secondary dam support,
drainage tubing, and ceiling panels in the forward lobe of the forward
cargo compartment.
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 1 airplane of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Installation........................ 16 work-hours x $85 per Up to $27,077.............. Up to $28,437.............. Up to $28,437.
hour = $1,360 per
installation.
--------------------------------------------------------------------------------------------------------------------------------------------------------
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.
List of Subjects in 14 CFR Part 39

reference, Safety.
