14 CFR Part 39

[Docket No. FAA-2012-1273; Directorate Identifier 2012-CE-045-AD]
RIN 2120-AA64


Airworthiness Directives; Cessna Aircraft 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 Cessna Aircraft Company Models 172R and 172S airplanes. This 
proposed AD was prompted by reports of chafing of a new configuration 
of the fuel return line assembly, which was caused by the fuel return 
line assembly rubbing against the right steering tube assembly during 
rudder pedal actuation. This proposed AD would require you to install 
the forward and aft fuel return line support clamps and brackets; 
inspect for a minimum clearance between the fuel return line assembly 
and the steering tube assembly and clearance between the fuel return 
line assembly and the airplane structure; and, if any damage is found, 
replace the fuel return line assembly. We are proposing this AD to 
correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by January 22, 
2013.

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

Discussion

    In January 2012, we issued AD 2012-02-02 (77 FR 6003, February 7, 
2012), and in October 2012, we issued AD 2012-22-01 (77 FR 70114, 
November 23, 2012) for certain Cessna Aircraft Company (Cessna) Models 
172R and 172S airplanes. These ADs required inspection of the fuel 
return line assembly for chafing; replacement of the fuel return line 
assembly if chafing is found; inspection of the clearance between the 
fuel return line assembly and both the right steering tube assembly and 
the airplane structure; and adjustment as necessary. The ADs resulted 
from reports of chafed fuel return line assemblies, which were caused 
by the fuel return line assembly rubbing against the right steering 
tube assembly during full rudder pedal actuation. We issued these ADs 
to detect and correct chafing of the fuel return line assembly, which 
could result in fuel leaking under the floor and fuel vapors entering 
the cabin. This condition could lead to fire under the floor or in the 
cabin area.
    We were recently notified that the unsafe condition also applies to 
airplanes with different serial number effectivity.

Relevant Service Information

    We reviewed Cessna Aircraft Company Service Bulletin SEB-28-01, 
dated September 21, 2012. The service information describes procedures 
for fuel return line inspection and modification.

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

    We estimate the following costs to do any necessary replacement 
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 replacement:

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

    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.
