Airworthiness Directives; Cessna Aircraft Company (Type 
Certificate Previously Held by Columbia Aircraft Manufacturing 
(Previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and 
LC42-550FG Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2009-09-
09, which applies to certain Cessna Aircraft Company (Cessna) (type 
certificate previously held by Columbia Aircraft Manufacturing 
(previously The Lancair Company)) Models LC40-550FG, LC41-550FG, and 
LC42-550FG airplanes. AD 2009-09-09 currently requires repetitive 
inspections of the rudder hinges and the rudder hinge brackets for 
damage, i.e., cracking, deformation, and discoloration. If damage is 
found during any inspection, AD 2009-09-09 also requires replacing the 
damaged rudder hinge and/or rudder hinge bracket. Since we issued AD 
2009-09-09, Cessna has developed a modification that, when 
incorporated, would terminate the repetitive inspections required by AD 
2009-09-09. The FAA has determined that long-term continued operational 
safety will be better assured by design changes that removed the source 
of the problem, rather than by repetitive inspections or other special 
procedures. Consequently, this proposed AD would retain the inspection 
requirements of AD 2009-09-09 and add a terminating action for the 
inspection requirements. We are proposing this AD to detect and correct 
damage in the rudder hinges and the rudder hinge brackets, which could 
result in failure of the rudder. This failure could lead to loss of 
control.

DATES: We must receive comments on this proposed AD by February 1, 
2010.

Discussion

    We received reports of a cracked lower rudder hinge bracket on two 
Cessna Model LC41-550FG airplanes that caused us to issue AD 2009-09-
09, Amendment 39-15895 (74 FR 19873, April 30, 2009). AD 2009-09-09 
currently requires the following on certain Cessna Models LC40-550FG, 
LC41-550FG, and LC42-550FG airplanes:
     Repetitively inspecting the rudder hinges and the rudder 
hinge brackets for damage; and
     Replacing the rudder hinge and/or rudder hinge bracket if 
damage is found.
    Cessna developed a modification that, when incorporated, would 
eliminate the need for the repetitive inspections required by AD 2009-
09-09. The FAA has determined that long-term continued operational 
safety will be better assured by design changes that removed the source 
of the problem, rather than by repetitive inspections or other special 
procedures.
    This condition, if not corrected, could result in failure of the 
rudder. This failure could lead to loss of control.

Relevant Service Information

    We have reviewed Cessna Single Engine Service Bulletin SB09-27-01, 
Revision 2, dated November 23, 2009.
    The service information describes procedures for repetitively 
inspecting the rudder hinges and the rudder hinge brackets for damage, 
i.e., cracking, deformation, and discoloration. The service information 
also describes procedures for incorporating a modification kit that 
will terminate the repetitive inspections.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This proposed AD 
would supersede AD 2009-09-09 with a new AD that would retain the 
inspection requirements of AD 2009-09-09 and add a terminating action 
for the inspection requirements. This proposed AD would require you to 
use the service information described previously to perform these 
actions.

Costs of Compliance

    We estimate that this proposed AD would affect 535 airplanes in the 
U.S. registry.
    We estimate the following costs to do the proposed inspections:

----------------------------------------------------------------------------------------------------------------
                                                                                  Total cost per   Total cost on
                  Labor cost                               Parts cost                airplane     U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspection with rudder removed: 1.2 work-hours  Not applicable..................             $96         $51,360

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

     We estimate the following costs to do the proposed modification:

------------------------------------------------------------------------
                                                          Total cost per
               Labor cost                   Parts cost       airplane

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket that contains the proposed AD, the 
regulatory evaluation, any comments received, and other information on 
the Internet at http://www.regulations.gov; or in person at the Docket 
Management Facility between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Office (telephone (800) 647-5527) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.
