 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. 2000-CE-61-AD; Amendment 39-12139; AD 2001-05-03]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration, DOT.
 ACTION: Final rule.
 SUMMARY: This amendment adopts a new airworthiness directive (AD) that applies to certain SOCATA—Groupe AEROSPATIALE (Socata) Model TBM 700 airplanes. This AD requires you to apply Loctite on attaching bolt/screw threads of inboard, central, and outboard carriages; increase tightening torques of associated hardware; and replace central carriage attaching bolts. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this AD are intended to prevent loose, or the loss of, flap attaching bolts/screws, which could cause rough or irregular control. Such rough or irregular control could lead to the loss of control of the airplane.
 DATES: This AD becomes effective on April 27, 2001. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of April 27, 2001.
 ADDRESSES: You may get the service information referenced in this AD from SOCATA Groupe AEROSPATIALE, Customer Support, Aerodrome Tarbes-Ossun-Lourdes, BP 930-F65009 Tarbes Cedex, France; telephone: (33) (0)5.62.41.73.00; facsimile: (33) (0)5.62.41.76.54; or the Product Support Manager, SOCATA—Groupe AEROSPATIALE, North Perry Airport, 7501 Pembroke Road, Pembroke Pines, Florida 33023; telephone: (954) 894-1160; facsimile: (954) 964-4191.

SUPPLEMENTARY INFORMATION: Discussion *What events have caused this AD?*
                     The Direction Ge
                    
                    ne
                    
                    rale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified FAA that an unsafe condition may exist on certain Socata Model TBM 700 airplanes. The DGAC reports two occurrences on Socata model TBM 700 airplanes where, following a flight, a screw of a flap attachment fitting was found partly unscrewed and another was missing. These occurrences are the result of flap vibration. *What are the consequences if the condition is not corrected?*
                     Loose or the loss of flap attaching bolts/screws could result in rough or irregular control. Such rough or irregular control could lead to loss of control of the airplane. *Has FAA taken any action to this point?*
                     We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Socata Model TBM 700 airplanes. This proposal was published in the 
                    **Federal Register**
                     as a notice of proposed rulemaking (NPRM) on January 2, 2001 (66 FR 64). The NPRM proposed to require you to apply Loctite on attaching bolt/screw threads of inboard, central, and outboard carriages; increase tightening torques of associated hardware; and replace central carriage attaching bolts. *Was the public invited to comment?*
                     Interested persons were afforded an opportunity to participate in the making of this amendment. No comments were received on the proposed rule or the FAA's determination of the cost to the public. Socata has revised Service Bulletin No. SB 70-087 57, dated September 2000 (Amendment 1, dated November 2000), to incorporate minor procedural changes. This AD requires no further action if the original service bulletin is accomplished. FAA's Determination *What is FAA's final determination on this issue?*
                     After careful review of all available information related to the subject presented above, we have determined that air safety and the public interest require the adoption of the rule as proposed except for the addition of the revised service information and minor editorial corrections. We determined that this addition and these minor corrections: —Will not change the meaning of the AD; and —Will not add any additional burden upon the public than was already proposed. Cost Impact *How many airplanes does this AD impact?*
                     We estimate that this AD affects 75 airplanes in the U.S. registry. *What is the cost impact of this AD on owners/operators of the affected airplanes?*
                     We estimate the following costs to accomplish the modification: Labor cost
Parts cost
Total cost per airplane
Total cost on U.S. 
                             operators6 workhours × $60 per hour = $360
$10
$360 + $10 = $370
$370 × 75 = $27,750
 
 
 Regulatory Impact *Does this AD impact various entities?*
                     The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132. *Does this AD involve a significant rule or regulatory action?*
                     For the reasons discussed above, I certify that this action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under 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. A copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption
