The Direction Generale De L'Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified the FAA that an unsafe condition may exist on Eurocopter France Model AS-365N2, SA-360C, SA-365C, C1, C2, N, N1, and SA-366G1 helicopters. The DGAC advises that inspecting for broken or out-of-tolerance attachment springs on the fairing, replacing broken attachment springs and attachment springs that are out-of-tolerance, and marking the fairing are necessary due to reports of broken attachment springs. \n\n\tEurocopter France has issued SA-360C, SA-365C, C1, C2 Service Bulletin No. 01.34, dated 96-14(N); SA-365N Service Bulletin No. 01.00.43, dated 96-14(N); SA-365N1, AS-365N2 Service Bulletin No. 01.00.42, dated 96-14(N), and SA-366G1 Service Bulletin No. 01.22, dated 96-14(N). These service bulletins specify several actions regarding the fairing and attachment springs. The DGAC classified these service bulletins as mandatory and issued AD 95-107-039(B)R1 and AD 95-112-040(B), both dated June 7, 1995, and AD 95-108-018(B), dated May 24, 1995, in order to assure the continued airworthiness of these helicopters in France. \n\n\tThese helicopter models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation previously described. The FAA has examined the findings of the DGAC, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. \n\n\tSince an unsafe condition has been identified that is likely to exist or develop on other Model AS-365N2, SA-360C, SA-365C, C1, C2, N, N1, and SA-366G1 helicopters of the same type design registered in the United States, this AD is being issued to prevent failure of the attachment springs which could cause loss of the tail rotor hub fairing, damage to the tail rotor, and subsequent loss of control of the helicopter. This AD requires inspecting for broken or out-of-tolerance attachment springs on the fairing, replacing broken attachment springs and those that are out-of-tolerance, and marking the fairing with an "X" by the fairing part number to indicate compliance. \n\n\tThe short compliance time involved is required because the previously described critical unsafe condition can adversely affect the controllability of the helicopter. Therefore, the inspections, replacement, and marking are required prior to further flight, and this AD must be issued immediately. \n\n\tSince a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for prior public comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days. \n\n\tThe FAA estimates that 135 helicopters of U.S. registry will be affected by this AD, that it will take 1.5 work hours per helicopter to accomplish the actions, and that the average labor rate is $60 per work hour. Required parts will cost approximately $988 per helicopter. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $145,530. \n\nComments Invited \n\tAlthough this action is in the form of a final rule that involves requirements affecting flight safety and, thus, was not preceded by notice and an opportunity for public comment, comments are invited on this rule. Interested persons are invited to comment on this rule by submitting such written data, views, or arguments as they may desire. Communications should identify the Rules Docket number and be submitted in triplicate to the address specified under the caption "ADDRESSES." All communications received on or before the closing date for comments will be considered, and this rule may be amended in light of the comments received. Factual information that supports the commenter's ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether additional rulemaking action would be needed. \n\n\tComments are specifically invited on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. All comments submitted will be available, both before and after the closing date for comments, in the Rules Docket for examination by interested persons. A report that summarizes each FAA-public contact concerned with the substance of this AD will be filed in the Rules Docket. \n\n\tCommenters wishing the FAA to acknowledge receipt of their comments submitted in response to this rule must submit a self-addressed, stamped postcard on which the following statement is made: "Comments to Docket No. 98-SW-05-AD." The postcard will be date stamped and returned to the commenter. \n\n\tThe 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. \n\n\tThe FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and that it is not a "significant regulatory action" under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket. A copy of it, if filed, may be obtained from the Rules Docket at the location provided under the caption "ADDRESSES." \n\nList of Subjects in 14 CFR Part 39 \n\tAir transportation, Aircraft, Aviation safety, Safety. \n\nAdoption of the Amendment \n\tAccordingly, pursuant to 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: \n\nPART 39 - AIRWORTHINESS DIRECTIVES \n\t1. The authority citation for part 39 continues to read as follows: \n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n§ 39.13 (Amended) \n\t2. Section 39.13 is amended by adding a new airworthiness directive to read as follows:
