    SUMMARY: This amendment adopts a new airworthiness directive (AD) 
    applicable to Eurocopter France Model SA-360C, SA-365C, C1, and C2 
    helicopters. This action requires replacing certain electrical modules 
    with airworthy electrical modules. This amendment is prompted by the 
    discovery of several defective electrical modules. This condition if 
    not corrected could result in loss of electrical continuity, which 
    could cause loss of critical rotorcraft electrical systems and 
    subsequent loss of control of the helicopter.
    
    DATES: Effective October 19, 1999.

    SUPPLEMENTARY INFORMATION: The Direction Generale De L'Aviation Civile 
    (DGAC), the airworthiness authority for France, recently notified the 
    FAA that an unsafe condition may exist on Eurocopter France Model SA-
    360C, SA-365C, C1, and C2 helicopters. The DGAC advises of the 
    malfunctions due to faulty ``CONNECTRAL'' modules on electrical 
    circuits of a Super Puma AS332 helicopter.
        Eurocopter France has issued Eurocopter Service Bulletin No. 01.37, 
    dated May 28, 1998 (SB), for Model SA-360C, SA-365C, C1, and C2 
    helicopters. The SB specifies inspecting and replacing ``CONNECTRAL'' 
    green electrical modules having a manufacturing code of 95/16 through 
    96/21. The manufacturing code identifies the year and week of module 
    production. The electrical modules identified by a white dot on the 
    face are airworthy and do not need to be replaced. The DGAC classified 
    this SB as mandatory and issued AD 98-252-043(A), dated July 1, 1998, 
    to ensure the continued airworthiness of these helicopters in France.
        These helicopter models are manufactured in France and are type 
    certificated for operation in the United States under the provisions of 
    Sec. 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 described above. 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.
        Since an unsafe condition has been identified that is likely to 
    exist or develop on other Eurocopter France Model SA-360C, SA-365C, C1, 
    and C2 helicopters of the same type design registered in the United 
    States, this AD is being issued to prevent loss of electrical 
    continuity, which could cause loss of critical systems and subsequent 
    loss of control of the helicopter. This AD requires replacing each 
    ``CONNECTRAL'' green electrical module having a manufacturing code of 
    95/16 through 96/21 with an airworthy electrical module. Replacing the 
    electrical modules identified with a white dot on the face is not 
    required because the manufacturer has verified the proper functioning 
    of these units.
        None of the Model SA-360C, SA-365C, C1, and C2 helicopters affected 
    by this action are on the U.S. Register. All helicopters included in 
    the applicability of this rule are operated by non-U.S. operators under 
    foreign registry; therefore, they are not directly affected by this AD 
    action. However, the FAA considers that this rule is necessary to 
    ensure that the unsafe condition is addressed in the event that any of 
    these
    
    [[Page 53626]]
    
    subject helicopters are imported and placed on the U.S. Register in the 
    future.
        Should an affected helicopter be imported and placed on the U.S. 
    Register in the future, it would require approximately 120 work hours 
    per helicopter to accomplish the proposed actions at an average labor 
    rate of $60 per work hour. Required parts would cost approximately 
    $7,282 for the maximum number of modules replaced per helicopter, but 
    the helicopter manufacturer has stated that the parts will be provided 
    at no cost. Based on these figures, the total cost impact of this AD 
    would be $7,200 per helicopter.
        Since this AD action does not affect any helicopter that is 
    currently on U.S. Register, it has no adverse economic impact and 
    imposes no additional burden on any person. Therefore, notice and 
    public procedures hereon are unnecessary and the amendment may be made 
    effective in less than 30 days after publication in the Federal 
    Register.
    
    Comments Invited
    
        Although 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.
        Comments 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.
        Commenters 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. 99-SW-15-AD.'' The postcard will be date stamped and 
    returned to the commenter.
        The regulations adopted herein would 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.
        The FAA has determined that notice and public comment are 
    unnecessary in promulgating this regulation; therefore, it can be 
    issued immediately to correct an unsafe condition in aircraft since 
    none of these model helicopters are registered in the United States. 
    The FAA has also determined that this regulation 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.

    Adoption of the Amendment
    
        Accordingly, pursuant to the authority delegated to me by the 
    Administrator, the Federal Aviation Administration proposes to amend 
    part 39 of the Federal Aviation Regulations (14 CFR part 39) as 
    follows:
    
    PART 39--AIRWORTHINESS DIRECTIVES
    
        1. The authority citation for part 39 continues to read as follows:
    
        Authority: 49 U.S.C. 106(g), 40113, 44701.
    
    
    Sec. 39.13  [Amended]
    
        2. Section 39.13 is amended by adding a new airworthiness directive 
    to read as follows:
    
    AD 99-21-01  Eurocopter France: Amendment 39-11344, Docket No. 99-
    SW-15-AD.
    
        Applicability: Model SA-360C, SA-365 C, C1, and C2 helicopters, 
    certificated in any category.
    
        Note 1: This AD applies to each helicopter identified in the 
    preceding applicability provision, regardless of whether it has been 
    otherwise modified, altered, or repaired in the area subject to the 
    requirements of this AD. For helicopters 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 within 400 hours time-in-service or within 
    6 calendar months, whichever occurs first, unless accomplished 
    previously.
        To prevent loss of electrical continuity, which could cause loss 
    of critical rotorcraft electrical systems and subsequent loss of 
    control of the helicopter, accomplish the following:
        (a) Remove and replace each ``CONNECTRAL'' green electrical 
    module that does not have a white dot on the face and that has a 
    manufacturing code of 95/16 through 96/21 with an airworthy 
    electrical module.
    
        Note 2: Eurocopter France Service Bulletin No. 01.37, dated May 
    28, 1998, pertains to the subject of this AD.
    
        (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, Rotorcraft Standards Staff, 
    Rotorcraft Directorate, FAA. Operators shall submit their requests 
    through an FAA Principal Maintenance Inspector, who may concur or 
    comment and then send it to the Manager, Standards Staff.
    
        Note 3: Information concerning the existence of approved 
    alternative methods of compliance with this AD, if any, may be 
    obtained from the Rotorcraft Standards Staff.
    
        (c) Special flight permits may be issued in accordance with 
    Secs. 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 
    21.197 and 21.199) to operate the helicopter to a location where the 
    requirements of this AD can be accomplished.
    
        Note 4: The subject of this AD is addressed in Direction 
    Generale De L'Aviation Civile AD 98-252-043(A), dated July 1, 1998.
        Issued in Fort Worth, Texas, on September 24, 1999.
