    Airworthiness Directives; Bell Helicopter Textron, Inc. Model 
    206A, 206B, 206L, 206L-1, and 206L-3 Helicopters
    
    AGENCY: Federal Aviation Administration, DOT.
    
    ACTION: Final rule.

    SUMMARY: This amendment adopts a new airworthiness directive (AD), 
    applicable to Bell Helicopter Textron, Inc. (BHTI) Model 206A, 206B, 
    206L, 206L-1, and 206L-3 helicopters, that requires installing a 
    protective mechanical fuel valve switch guard on the fuel valve switch. 
    This amendment is prompted by reports of airmen inadvertently placing 
    the fuel valve switch to the ``OFF'' position. The actions specified by 
    this AD are intended to prevent the fuel valve switch from being 
    inadvertently placed in the ``OFF'' position, which could result in an 
    engine failure and a subsequent power-off landing.
    
    DATES: Effective June 8, 1995.
        The incorporation by reference of certain publications listed in 
    the regulations is approved by the Director of the Federal Register as 
    of June 8, 1995.
    
    ADDRESSES: The service information referenced in this AD may be 
    obtained from Bell Helicopter Textron, Inc., Attention: Customer 
    Support, P.O. Box 482, Fort Worth, Texas 76101. This information may be 
    examined at the FAA, Office of the Assistant Chief Counsel, 2601 
    Meacham Blvd., Room 663, Fort Worth, Texas; or at the Office of the 
    Federal Register, 800 North Capitol Street, NW., suite 700, Washington, 
    DC.
    
    FOR FURTHER INFORMATION CONTACT: Mr. Lance Gant, Aerospace Engineer, 
    Rotorcraft Certification Office, Rotorcraft Directorate, FAA, 2601 
    Meacham Blvd., Fort Worth, Texas 76137, telephone (817) 222-5141, fax 
    (817) 222-5959.
    
    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 Bell Helicopter Textron, Inc. 
    (BHTI) Model 206A, 206B, 206L, 206L-1, and 206L-3 helicopters was 
    published in the Federal Register on November 14, 1994 (59 FR 56436). 
    [[Page 21977]] That action proposed to require installing a protective 
    mechanical fuel valve switch guard on the fuel valve switch.
        Interested persons have been afforded an opportunity to participate 
    in the making of this amendment. No comments were received on the 
    proposal or the FAA's determination of the cost to the public. The FAA 
    has determined that air safety and the public interest require the 
    adoption of the rule as proposed, except for editorial changes.
        The FAA estimates that 5,192 helicopters of U.S. registry will be 
    affected by this AD, that it will take approximately 1 work hour per 
    helicopter to accomplish the required actions, and that the average 
    labor rate is $60 per work hour. Required parts will cost nothing for 
    these helicopters since the manufacturer is providing full warranty 
    compensation for the parts. Based on these figures, the total cost 
    impact of the AD on U.S. operators is estimated to be $311,520.
        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.

    Adoption of the Amendment
    
        Accordingly, 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:
    
    PART 39--AIRWORTHINESS DIRECTIVES
    
        1. The authority citation for part 39 continues to read as follows:
    
        Authority: 49 U.S.C. App. 1354(a), 1421 and 1423; 49 U.S.C. 
    106(g); and 14 CFR 11.89.
    
    
    Sec. 39.13  [Amended]
    
        2. Section 39.13 is amended by adding a new airworthiness directive 
    to read as follows:
    
    95-09-06  Bell Helicopter Textron, Inc.: Amendment 39-9209. Docket 
    No. 91-ASW-28.
    
        Applicability: Model 206A, 206B, 206L, 206L-1, and 206L-3 
    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 
    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 use the authority 
    provided in paragraph (b) to request approval from the FAA. This 
    approval may address either no action, if the current configuration 
    eliminates the unsafe condition, or different actions necessary to 
    address the unsafe condition described in this AD. Such a request 
    should include an assessment of the effect of the changed 
    configuration on the unsafe condition addressed by this AD. In no 
    case does the presence of any modification, alteration, or repair 
    remove any helicopter from the applicability of this AD.
    
        Compliance: Required as indicated, unless accomplished 
    previously.
        To prevent the fuel valve switch from being inadvertently placed 
    in the ``OFF'' position, which could result in an engine failure and 
    a subsequent power-off landing, accomplish the following:
        (a) Within the next 50 hours time-in-service after the effective 
    date of this airworthiness directive (AD), modify the fuel valve 
    switch to add a protective mechanical fuel valve switch guard as 
    follows:
        (1) For the Model 206A, serial numbers (S/N) 1 through 153, 
    modify in accordance with Part I of the Accomplishment Instructions 
    in BHTI Alert Service Bulletin (ASB) No. 206-90-54, dated May 31, 
    1990.
        (2) For the Model 206A, S/N 154 through 660 and 672 through 715,

    through 45790, and Model 206L-3, S/N 51001 through 51319, modify in

        (b) An alternative method of compliance or adjustment of the 
    compliance time that provides an acceptable level of safety may be 
    used when approved by the Manager, Rotorcraft Certification Office, 
    FAA, Rotorcraft Directorate. Operators shall submit their requests 
    through an FAA Principal Maintenance Inspector, who may concur or 
    comment and then send it to the Manager, Rotorcraft Certification 
    Office.
    
        Note 2: Information concerning the existence of approved 
    alternative methods of compliance with this AD, if any, may be
