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:

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written relevant data, views, or
arguments regarding this proposed AD. Send your comments to an address
listed under the ADDRESSES section. Include the docket number, ``FAA-
2008-1319; Directorate Identifier 2008-CE-071-AD'' at the beginning of
your comments. We specifically invite comments on the overall
regulatory, economic, environmental, and energy aspects of the proposed
AD. We will consider all comments received by the closing date and may
amend the proposed AD in light of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive concerning 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.
