Airworthiness Directives; Cessna Aircraft Company Models 208 and 
208B Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Cessna Aircraft Company (Cessna) Models 208 and 208B airplanes. 
This proposed AD would require you to modify the aileron carry-through 
cable attachment to the aileron upper quadrant with parts of improved 
design. This proposed AD results from reports of a ``catch'' in the 
aileron control system when the control yoke is turned. We are 
proposing this AD to prevent the cable attach fitting on the aileron 
upper quadrant assembly from rotating and possibly contacting or 
interfering with the aileron lower quadrant assembly, which could 
result in limited roll control and reduced handling capabilties.

DATES: We must receive comments on this proposed AD by February 17, 
2009.

ADDRESSES: Use one of the following addresses to comment on this 
proposed AD:

Discussion

    We have reports of a ``catch'' in the aileron control system when 
the control yoke is turned on a Cessna Aircraft Company (Cessna) Model 
208 airplane.
    The ``catch'' is caused by the cable end fitting, part number (P/N) 
2660033, rotating out of its normal position and rubbing against the 
lower aileron quadrant assembly, P/N 2660032-7.
    The reason that the cable end fitting rotates is unknown. Tension 
on the cable is what has been keeping the fitting flat and preventing 
rotation.
    Cessna Aircraft Company has reconfigured the design of the existing 
nut on the cable fitting with two jam nuts, a spring washer, and safety 
wire to prevent rotation of the cable end.
    This condition, if not corrected, could result in limited roll 
control and reduced handling capabilties.

Relevant Service Information

    We have reviewed Cessna Caravan Service Bulletin CAB08-6, dated 
October 27, 2008.
    The service information describes procedures for modifying the 
aileron carry-through cable attachment to the aileron upper quadrant.

FAA's Determination and Requirements of the Proposed AD

    We are proposing this AD because we evaluated all information and 
determined the unsafe condition

[[Page 76980]]

described previously is likely to exist or develop on other products of 
the same type design. This proposed AD would require you to modify the 
aileron carry-through cable attachment to the aileron upper quadrant 
with parts of improved design.

Costs of Compliance

    We estimate that this proposed AD would affect 794 airplanes in the 
U.S. registry.
    We estimate the following costs to do the proposed modification:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                  Labor cost                              Parts cost                airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $80 per hour = $160...........  Not applicable.................            $160         $127,040
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs and 
replacements that would be required based on doing the proposed 
modification. We have no way of determining the number of airplanes 
that may need these repairs or replacements.
    We estimate the following costs to do possible damage repair to the 
aileron lower quadrant assembly, if necessary:

------------------------------------------------------------------------
                                                          Total cost per
            Labor cost                  Parts cost           airplane
------------------------------------------------------------------------
.5 work-hours x $80 per hour =     Not applicable......             $40
 $40.
------------------------------------------------------------------------

    We estimate the following costs to do possible removal and 
installation of the aileron lower quadrant assembly, if necessary:

------------------------------------------------------------------------
                                                          Total cost per
            Labor cost                  Parts cost           airplane
------------------------------------------------------------------------
2 work-hours x $80 per hour =      Not applicable......            $160
 $160.
------------------------------------------------------------------------

    We estimate the following costs to do possible removal and 
installation of the headliner, if necessary:

------------------------------------------------------------------------
                                                          Total cost per
            Labor cost                  Parts cost           airplane
------------------------------------------------------------------------
16 work-hours x $80 per hour =     Not applicable......          $1,280
 $1,280.
------------------------------------------------------------------------

    Warranty credit will be given for parts and labor to the extent 
specified in the manufacturer's service bulletin.

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.
