14 CFR Part 39

[Docket No. FAA-2010-1084; Directorate Identifier 2010-CE-056-AD; 
Amendment 39-17257; AD 2012-23-01]
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 all 
Cessna Aircraft Company (Cessna) Model 402C airplanes modified by 
Supplemental Type Certificate (STC) SA927NW and Model 414A airplanes 
modified by STC SA892NW. This AD was prompted by report of a Cessna 
Model 414A airplane modified by STC SA892NW that experienced an 
asymmetrical flap condition causing an uncommanded roll when the pilot 
set the flaps to the approach position. We are issuing this AD to 
prevent failure of the flap system, which could result in an 
asymmetrical flap condition. This condition could result in loss of 
control.

DATES: This AD is effective December 26, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 26, 
2012.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to include an airworthiness directive (AD) that 
would apply to the specified products. That SNPRM published in the 
Federal Register on August 23, 2012 (77 FR 50954). The original NPRM 
(75 FR 66700, October 29, 2010) proposed to require a complete 
inspection of the flap system and modification of the flap control 
system. The SNPRM (77 FR 50954, August 23, 2012) proposed to 
incorporate additional service information that addresses proper 
rigging procedures and corrective actions following additional 
inspection procedures.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM (77 FR 50954, August 23, 
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

[[Page 69743]]

as proposed except for minor editorial changes. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM (77 FR 50954, August 23, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Costs of Compliance

    We estimate that this proposed AD affects 150 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this AD:

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.
