14 CFR Part 39

[Docket No. FAA-2011-1245; Directorate Identifier 2011-CE-033-AD; 
Amendment 39-16925; AD 2012-02-02]

Airworthiness Directives; Cessna Aircraft Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain Cessna Aircraft Company (Cessna) Models 172R and 172S 
airplanes. That AD currently requires you to inspect the fuel return 
line assembly for chafing; replace the fuel return line assembly if 
chafing is found; and inspect the clearance between the fuel return 
line assembly and both the right steering tube assembly and the 
airplane structure, adjusting as necessary. Since we issued that AD, we 
have received a field report of a fuel return line chafing incident on 
a Cessna Model 172 airplane with a serial number (S/N) that was not 
included in the AD. This AD retains the actions of the current AD and 
adds S/Ns to the Applicability section of the AD. Chafing of the fuel 
return line assembly could lead to fire. This new AD requires the 
actions of the current AD and adds S/Ns to the Applicability section of 
the AD. We are issuing this AD to correct the unsafe condition on these 
products.

DATES: This AD is effective March 13, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 13, 
2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of March 
6, 2008 (73 FR 5737, January 31, 2008).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2008-03-02, Amendment 39-15351 (73 FR 5737, 
January 31, 2008). That AD applies to the specified products. The NPRM 
published in the Federal Register on November 14, 2011 (76 FR 70379). 
That NPRM proposed to continue to require actions of the current AD and 
add S/Ns to the Applicability section of the AD.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (76 FR 70379, November 14, 
2011) 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 (76 FR 70379, November 14, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 70379, November 14, 2011).

Costs of Compliance

    We estimate that this AD affects 768 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    The difference in estimated costs of this AD and AD 2008-03-02 (73 
FR 5737, January 31, 2008) is an increase in the estimated labor cost 
for those airplanes affected by AD 2008-03-02 and the costs of the 
additional airplanes added to the AD.
    We estimate the following costs to do any necessary replacements 
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

    We have 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),
    (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.
