On page 57874, add the following immediately following the Paperwork Reduction Act information for the ‘‘Direct Loan Servicing—Regular’’ (column 3, above the request for comments): Title: Direct Loan Servicing—Special. OMB Control Number: 0560–NEW. Type of Request: New Collection. Abstract: This information collection is required to support the proposed regulatory changes that include equine losses as eligible for EM. Some of the same information collection activities that will be used are currently approved for 7 CFR part 766, Direct Loan Servicing—Special, which establishes the requirements related to special servicing actions associated with direct loans including emergency loans. Emergency loan applicants tend to pose a higher economic risk of loss than those operations financed by commercial creditors. Information collections established in the regulations are necessary for FSA to actively supervise and provide credit counseling, management advice, and financial guidance. Estimate of Burden: Public reporting for this collection of information is estimated to average 47 minutes per response. Type of Respondents: Individuals or households, businesses or other for profit, and farms. Estimated Number of Respondents: 7. Estimated Number of Responses per Respondent: 2.5. Estimated Total Annual Number of Responses: 18. Estimated Total Annual Burden on Respondents: 26 hours. Once this information collection request is approved, FSA will incorporate this collection into existing collections package 0560–0233. Signed in Washington, DC, on October 21, 2010. Jonathan W.

Discussion We received a report of a Cessna Model 414 airplane, modified by Sierra Industries, Ltd., STC SA892NW (formerly held by Robertson Aircraft Corporation) that experienced an asymmetrical flap condition causing an un-commanded roll when the pilot set the flaps to the approach position. The flap preselect cable connects to the arm assembly and provides the flap position to the flap selector to close the position loop for the flap position. Micro switches are located on the arm assembly and provide the electrical signal for the arm position. STC SA927NW and STC SA892NW use the original production preselect cable. However, the STCs added an extension to the arm assembly that E:\FR\FM\29OCP1.SGM 29OCP1 66701 Federal Register / Vol. 75, No. 209 / Friday, October 29, 2010 / Proposed Rules requires increased travel of the preselect cable to obtain the same rotation as previously obtained with the shorter arm assembly. To obtain the same arm assembly rotation, the preselect cable must travel approximately an additional .75 inch. However, the original cable has internal mechanical stops that prevent it from traveling the additional distance. The cable’s internal stops are contacted by a smaller rotation displacement of the arm assembly. Since more linear displacement of the cable is required to obtain the same switch action, the internal mechanical stops of the cable are reached before the switches designed to stop the motion of the flaps activate. As a result, when the internal stops in the cable are contacted, the rotation of the arm assembly carrying the micro switches stops and the switch to stop the drive motor is not activated. Because the switch is not activated, the motor continues to run until either the motor drive shear pin fails, a cable breaks, the structural bracket breaks, or the secondary switches stop the motor before something breaks. The sequence was verified on the reported airplane by the rigging, installation, and operation of an STC production configuration. This condition, if not corrected, could result in an asymmetrical flap condition. This failure could lead to loss of control. Relevant Service Information We reviewed Sierra Industries, Ltd. Service Bulletin SI09–82 Series–1, Rev. IR, dated September 8, 2010. The service information describes procedures for inspecting the flap system, installing a new preselect cable with increased internal stroke, making additional component modifications, and installing and rigging the flap control system. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously. 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 proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspect the flap system and modify/replace the flap preselect control cable. 20 work-hours × $85 per hour = $1,700 .............. $1,000 $2,700 $405,000 Authority for This Rulemaking WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety.

Discussion

    We received a report of a Cessna Model 414 airplane, modified by 
Sierra Industries, Ltd., STC SA892NW (formerly held by Robertson 
Aircraft Corporation) that experienced an asymmetrical flap condition 
causing an un-commanded roll when the pilot set the flaps to the 
approach position. The flap preselect cable connects to the arm 
assembly and provides the flap position to the flap selector to close 
the position loop for the flap position. Micro switches are located on 
the arm assembly and provide the electrical signal for the arm 
position.
    STC SA927NW and STC SA892NW use the original production preselect 
cable. However, the STCs added an extension to the arm assembly that

[[Page 66701]]

requires increased travel of the preselect cable to obtain the same 
rotation as previously obtained with the shorter arm assembly. To 
obtain the same arm assembly rotation, the preselect cable must travel 
approximately an additional .75 inch. However, the original cable has 
internal mechanical stops that prevent it from traveling the additional 
distance. The cable's internal stops are contacted by a smaller 
rotation displacement of the arm assembly. Since more linear 
displacement of the cable is required to obtain the same switch action, 
the internal mechanical stops of the cable are reached before the 
switches designed to stop the motion of the flaps activate.
    As a result, when the internal stops in the cable are contacted, 
the rotation of the arm assembly carrying the micro switches stops and 
the switch to stop the drive motor is not activated. Because the switch 
is not activated, the motor continues to run until either the motor 
drive shear pin fails, a cable breaks, the structural bracket breaks, 
or the secondary switches stop the motor before something breaks. The 
sequence was verified on the reported airplane by the rigging, 
installation, and operation of an STC production configuration.
    This condition, if not corrected, could result in an asymmetrical 
flap condition. This failure could lead to loss of control.

Relevant Service Information

    We reviewed Sierra Industries, Ltd. Service Bulletin SI09-82 
Series-1, Rev. IR, dated September 8, 2010. The service information 
describes procedures for inspecting the flap system, installing a new 
preselect cable with increased internal stroke, making additional 
component modifications, and installing and rigging the flap control 
system.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

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 proposed 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

    We 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 this 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),
    (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.

Cessna Aircraft Company: Docket No. FAA-2010-1084; Directorate 
Identifier 2010-CE-056-AD.

Comments Due Date

    (a) We must receive comments by December 13, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Cessna Aircraft Company (Cessna) Model 
402C airplanes modified by Supplemental Type Certificate (STC) 
SA927NW and Model 414A airplanes modified by STC SA892NW, all serial 
numbers, that are certificated in any category.

Subject

    (d) Joint Aircraft System Component (JASC)/Air Transport 
Association (ATA) of America Code 57, Wings.

Unsafe Condition

    (e) This AD was prompted by a report of a Cessna Model 414A 
airplane modified by STC SA892NW that experienced an asymmetrical 
flap condition causing an un-commanded 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.
