Costs of Compliance

We estimate that this AD affects 794 airplanes in the U.S. registry.

We estimate the following costs to do the modification: Total cost per Total cost on Labor cost Parts cost airplane U.S. operators 2 workhours x $80 per hour = $160......... Not applicable............... $160 $127,040

We estimate the following costs to do any necessary repairs and replacements that will be required based on doing the 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 workhour 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 workhours 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 workhours 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 AD. Regulatory Findings

We have determined that 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. [[Page 10457]]

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 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 summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include ``Docket No. FAA20081319; Directorate Identifier 2008CE071AD'' in your request.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. FAA amends Sec. 39.13 by adding the following new AD:
20090512 Cessna Aircraft Company: Amendment 3915836; Docket No. FAA20081319; Directorate Identifier 2008CE071AD.
Effective Date
(a) This AD becomes effective on April 15, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the following airplane models and serial numbers that are certificated in any category:
Model Serial Nos.
208......................... 20800001 through 20800415 and 20800417 through 20800419.
208B........................ 208B0001 through 208B1081, 208B1083 through 208B1215, 208B1217 through 208B1257, 208B1259 through 208B1305, 208B1307, and 208B1309 through 208B1310. Unsafe Condition
(d) This AD results from reports of a ``catch'' in the aileron control system when the control yoke is turned. We are issuing 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 capabilities.
Compliance
(e) To address this problem, you must do the following, unless already done:
Actions Compliance Procedures Modify the aileron carrythrough Within the next Follow the cable attachment to the aileron 100 hours timein Accomplishment upper quadrant with parts of service after Instructions in improved design. April 15, 2009 Cessna Caravan (the effective Service Bulletin date of this AD) CAB086, dated or within the October 27, 2008. next 6 months

this AD),
whichever occurs
first.
Alternative Methods of Compliance (AMOCs)
(f) The Manager, Wichita Aircraft Certification Office (ACO), FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to
