 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2009-0489; Directorate Identifier 2009-CE-025-AD]
RIN 2120-AA64
 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 Air Tractor, Inc. (Air Tractor) Models AT-802 and AT-802A airplanes. This proposed AD would require installing a rudder-aileron interconnect cable system shield kit and securing any items stowed in the baggage compartment using tie downs and/or a cargo net until the cable shield kit is installed. This proposed AD results from a report of the rudder pedal cable becoming jammed in flight. We are proposing this AD to prevent jamming of the rudder-aileron interconnect cables by unsecured items in the baggage compartment, which could result in failure of the rudder-aileron interconnect cable system. This failure could lead to loss of control.
 DATES: We must receive comments on this proposed AD by July 28, 2009.

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-2009-0489; Directorate Identifier  2009-CE-025-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 received a report of an Air Tractor Model AT-802 airplane rudder pedal jamming in flight. The pilot was able to maintain control and land. After landing, a cable pulley in the rudder system was found broken. Air Tractor believes one or more unsecured items in the baggage compartment became entangled in the cables and caused them to jam, resulting in failure of the pulley. Air Tractor has designed a modification kit that installs shielding in the baggage compartment to prevent unsecured stowed items from becoming entangled in the rudder-aileron interconnect cable system. This condition, if not corrected, could result in jamming of the rudder-aileron interconnect cables by unsecured items in the baggage compartment, which could result in failure of the rudder-aileron interconnect cable system. This failure could lead to loss of control. Relevant Service Information We have reviewed Snow Engineering Co., Service Letter #274, Revision A, dated April 6, 2009. The service information describes procedures for installing a cable shield in the baggage compartment. 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 require installing a rudder-aileron interconnect cable system shield kit and securing any items stowed in the baggage compartment using tie downs and/or a cargo net until the cable shield kit is installed. Normally, the FAA would use a compliance time of hours time-in-service (TIS) or a certain number of months. The proposed AD uses a calendar date for compliance instead of hours TIS or a certain number of months. We are using the calendar date of before December 31, 2009, to allow owners with airplanes used in agricultural spray operations until the end of the spray season to install the rudder-aileron interconnect cable system shields (terminating action). Differences Between This Proposed AD and the Service Information This proposed AD would require securing stowed items in the baggage compartment with tie-down straps or a cargo net until the rudder-aileron interconnect cable system shield required in the proposed AD is 
                    ( print page 25685)
                    installed. The requirements of this proposed AD, if adopted as a final rule, would take precedence over the provisions in the service information. Costs of Compliance We estimate that this proposed AD would affect 210 airplanes in the U.S. registry. We estimate the following costs to do the proposed modification: Labor cost
Parts cost
Total cost per airplane
Total cost on U.S. 
                             operatorsCable Shield Kit SL#274: 4.5 work-hours × $80 per hour = $360
$860
affects 170 airplanes at $1,220 each
$207,400Cable Shield Kit SL#274-2: 4.5 work-hours × $80 per hour = $360
540
affects 40 airplanes at $900 each
36,000
 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;*
