This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent loss of the movable joint of the aileron control rod, caused by deterioration of the hinges, which could result in reduced controllability of the airplane. ## The airworthiness directive 98-06-02 CONSTRUCCIONES AERONAUTICAS, S.A. (CASA): Amendment 39-10380. Docket 97-NM-277-AD. Applicability: Model C-212 airplanes, as listed in CASA Service Bulletin SB-212-27-48, dated February 28, 1996; certificated in any category. NOTE 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it. Compliance:Required as indicated, unless accomplished previously. To prevent loss of the movable joint of the aileron control rod, caused by deterioration of the hinges, which could result in reduced controllability of the airplane, accomplish the following: (a) Within 100 flight hours after the effective date of this AD, accomplish the requirements of paragraphs (a)(1) and (a)(2) of this AD in accordance with CASA Service Bulletin SB-212-27-48, dated February 28, 1996. (1) Perform an inspection of the spherical bearings of the aileron control rod to detect discrepancies. If any discrepancy is found, prior to further flight, replace the whole terminal. And (2) Install an improved retainer washer in the movable joint of the aileron control rod. (b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate.Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116. (c) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (d) The actions shall be done in accordance with CASA Service Bulletin SB-212-27-48, dated February 28, 1996. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from Construcciones Aeronauticas, S.A., Getafe, Madrid, Spain. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. NOTE 3: The subject of this AD is addressed in Spanish airworthiness directive 05/96, dated May 13, 1996. (e) This amendment becomes effective on April 15, 1998. ## Rule preamble ### Supplementary information A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to certain CASA Model C-212 series airplanes was published in the Federal Register on December 31, 1997 (62 FR 68237). That action proposed to require a one-time inspection to detect discrepancies of the spherical bearing of the aileron control rod, and corrective action, if necessary; and installation of an improved retainer washer in the movable joint of the aileron control rod. Comments Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were submitted in response to the proposal or the FAA's determination of the cost to the public. Conclusion The FAA has determined that air safety and the public interest require the adoption of the rule as proposed. Cost Impact The FAA estimates that 38 airplanes of U.S. registry will be affected by thisAD, that it will take approximately 5 work hours per airplane to accomplish the required actions, and that the average labor rate is $60 per work hour. Required parts will cost approximately $56 per airplane. Based on these figures, the cost impact of the AD on U.S. operators is estimated to be $13,528, or $356 per airplane. The cost impact figure discussed above is based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. Regulatory Impact The regulations adopted herein will not have substantial direct effects 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, in accordance with Executive Order 12612, it is determined that this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment. 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 final evaluation has been prepared for this action and it is contained in the Rules Docket. A copy of it may be obtained from the Rules Docket at the location provided under the caption "ADDRESSES."
