Federal Register Abstract
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.

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.

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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (76 FR 70379, November 14, 2011) for correcting the unsafe
condition; and
<bullet> 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.
