14 CFR Part 39

[Docket No. FAA-2006-25262; Directorate Identifier 2006-CE-39-AD; 
Amendment 39-14725; AD 2006-17-04]

Airworthiness Directives; The Cessna Aircraft Company Models 
172R, 172S, 182T, T182T, 206H, and T206H Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain The Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, 
T182T, 206H, and T206H airplanes. This AD requires you to inspect the 
two end fittings on each of the flexible fuel hoses located in the 
engine compartment for the correct torque values, and, if any incorrect 
torque values are found during the inspection, tighten the hose end 
fittings to the correct torque values. This AD results from one report 
of loose fuel hose connections to the fuel injector servo on a Cessna 
Model 172S airplane. We are issuing this AD to detect and correct any 
incorrect torque values of the end fittings of flexible fuel hoses in 
the engine compartment, which could result in the loss of fuel flow and 
fuel leakage. Loss of fuel flow could result in partial or complete 
loss of engine power and fuel leakage could result in an engine 
compartment fire.

DATES: This AD becomes effective on September 1, 2006.
    As of September 1, 2006, the Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in the regulation.
    We must receive any comments on this AD by October 17, 2006.

SUPPLEMENTARY INFORMATION:

Discussion

    We have received one report of loose fuel hose connections to the 
fuel injector servo on a Cessna Model 172S airplane.
    This condition, if not corrected, could result in the loss of fuel 
flow and fuel leakage. Loss of fuel flow could result in partial or 
complete loss of engine power and fuel leakage could result in an 
engine compartment fire.

Relevant Service Information

    We reviewed Cessna Service Bulletin No. SB06-71-02, dated June 19, 
2006. The service information describes procedures for inspecting the 
two end

[[Page 47712]]

fittings on each of the flexible fuel hoses located in the engine 
compartment for the correct torque values, and, if any incorrect torque 
values are found during the inspection, tighten the hose end fittings 
to the correct torque values.

FAA's Determination and Requirements of This AD

    We are issuing this AD because we evaluated all the information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This AD requires 
you to do the actions in the referenced service bulletin.
    In preparing this rule, we contacted type clubs and aircraft 
operators to get technical information and information on operational 
and economic impacts. We did not receive any information through these 
contacts. If received, we would have included a discussion of any 
information that may have influenced this action in the rulemaking 
docket.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and an opportunity for 
public comment. We invite you to send any written relevant data, views, 
or arguments regarding this AD. Send your comments to an address listed 
under the ADDRESSES section. Include the docket number ``FAA-2006-
25262; Directorate Identifier 2006-CE-39-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD. We will consider 
all comments received by the closing date and may amend the AD in light 
of those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact we 
receive concerning this AD.

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the AD, the regulatory 
evaluation, any comments received, and other information on the 
Internet at http://dms.dot.gov; or in person at the Docket Management 
Facility between 9 a.m. and 5 p.m., Monday through Friday, except 
Federal holidays. The Docket Office (telephone (800) 647-5227) is 
located at the street address stated in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.

Unsafe Condition

    (d) This AD is the result of one report of loose fuel hose 
connections to the fuel injector servo on a Cessna Aircraft Company 
Model 172S airplane. We are issuing this AD to detect and correct 
any incorrect torque values of the end fittings of flexible fuel 
hoses in the engine compartment, which could result in the loss of 
fuel flow and fuel leakage. Loss of fuel flow could result in 
partial or complete loss of engine power and fuel leakage could 
result in an engine compartment fire.
