14 CFR Part 39

[Docket No. FAA-2012-0846; Directorate Identifier 2012-CE-021-AD; 
Amendment 39-17237; AD 2012-22-01]
RIN 2120-AA64

Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Cessna Aircraft Company Models 172R and 172S airplanes. This AD was 
prompted by 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. This AD 
requires you to inspect the fuel return line assembly for chafing; 
replace the fuel return line assembly if chafing is found; inspect the 
clearance between the fuel return line assembly and both the right 
steering tube assembly and the airplane structure; and adjust as 
necessary. We are issuing this AD to correct the unsafe condition on 
these products.

DATES: This AD is effective December 28, 2012.
    Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of March 
13, 2012 (77 FR 6003, February 7, 2012).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM published in the Federal Register on August 20, 2012 (77 FR 
50054). That NPRM proposed to require you to inspect the fuel return 
line assembly for chafing; replace the fuel return line assembly if 
chafing is found; inspect the clearance between the fuel return line 
assembly and both the right steering tube assembly and the airplane 
structure; and adjust as necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 50054, August 20, 
2012) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 50054, August 20, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 50054, August 20, 2012).

Costs of Compliance

    We estimate that this AD affects 55 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

     We estimate the following costs to do any necessary replacements 
and adjustments that would be required based on the results of the 
inspection. We have no way of determining the number of aircraft that 
might need these replacements:

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

    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),
    (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.

right steering tube assembly and the clearance between the fuel 
return line assembly and the aircraft structure do not meet the 
minimums as specified in paragraphs (i)(l) and (i)(2) of this AD, 
before further flight, adjust the clearances to meet the required 
minimums following the Instructions paragraph of Cessna Service 
Bulletin SB07-28-01, Revision 1, dated September 22, 2011.
