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 Model 560XL airplanes. This AD was prompted by 
reports of wheel inserts becoming loose and damaging brake assemblies 
on Model 560XL airplanes. This AD requires an inspection of the torque 
lug and surrounding components (wheel base, side rim, lock ring) for 
damage (such as corrosion, cracks, dents, bent areas, damaged or 
missing paint or primer, or wear on the metal), and of the bearing cup 
for corrosion, turned cup, or clearance that exceeds limits, and repair 
as applicable; measuring the torque lugs for width and replacing screws 
and inserts with new, improved screws and inserts; and re-identifying 
the wheel assemblies. We are issuing this AD to prevent brake failure, 
which could result in an airplane not being able to stop on the runway.

DATES: This AD is effective June 7, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 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 January 19, 2012 (77 FR 
2659). That NPRM proposed to require an inspection of the torque lug 
and surrounding components (wheel base, side rim, lock ring) for damage 
(such as corrosion, cracks, dents, bent areas, damaged or missing paint 
or primer, or wear on the metal), and of the bearing

[[Page 26157]]

cup for corrosion, turned cup, or clearance that exceeds limits, and 
repair as applicable; measuring the torque lugs for width and replacing 
screws and inserts with new, improved screws and inserts; and re-
identifying the wheel assemblies.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 2659, January 19, 
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. In addition, we have re-identified Note 2 of 
the NPRM (77 FR 2659, January 19, 2012) as paragraph (h) of this final 
rule. We also revised the language in paragraph (j) of this AD; this 
change does not affect the intent of this AD. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 2659, January 19, 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 2659, January 19, 2012).

Costs of Compliance

    We estimate that this AD affects 473 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.

 marking.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs or 
replacements as applicable 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 repairs or replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                Action                        Labor cost               Parts cost            Cost per product
----------------------------------------------------------------------------------------------------------------
Repair or replacement as applicable..  Between 1 and 9 work-    Between $0 and $24,000   Between $85 and $24,765
                                        hour[s] x $85 per hour   per wheel assembly.      per wheel assembly.
                                        = Between $85 and $765
                                        per wheel assembly.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all of the costs of this 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

    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.
