SUPPLEMENTARY INFORMATION: RIN 2120–AA64 Airworthiness Directives; The Boeing Company Model 767–200 and –300 Series Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). Note 1: This AD differs from the MCAI and/or service information as follows: No differences. 62661 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. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments. • Fax: 202–493–2251. • Mail: U.S. Department of Transportation, Docket Operations, M– SUMMARY: PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 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 E:\FR\FM\11OCP1.SGM 11OCP1 62662 Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules 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 × $85 per hour = $1,360 per installation .. Up to $27,077 .. Up to $28,437 ... Up to $28,437. srobinson on DSK4SPTVN1PROD with PROPOSALS 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 VerDate Mar<15>2010 17:42 Oct 07, 2011 Jkt 223001 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.

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.

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.
