    ACTION: Notice of proposed rulemaking (NPRM).
    
    -----------------------------------------------------------------------
    
    SUMMARY: This document proposes to adopt a new airworthiness directive 
    (AD) that would apply to certain Beech Aircraft Corporation (Beech) 
    Models 60 and A60 airplanes. The proposed action would require 
    incorporating flight manual supplement revisions into the Airplane 
    Flight Manual (AFM) that would specify a minimum airspeed for operating 
    the affected airplanes in icing conditions. Reports of several 
    incidents and accidents on the affected airplanes related to flight in 
    icing conditions prompted the proposed action. The actions specified by 
    the proposed AD are intended to prevent loss of control of the airplane 
    because of the airplane traveling too slow in icing conditions.
    
    DATES: Comments must be received on or before August 4, 1995.
    
    ADDRESSES: Submit comments in triplicate to the Federal Aviation 
    Administration (FAA), Central Region, Office of the Assistant Chief

    Availability of NPRMs
    
        Any person may obtain a copy of this NPRM by submitting a request 
    to the FAA, Central Region, Office of the Assistant Chief Counsel, 
    Attention: Rules Docket No. 95-CE-23-AD, Room 1558, 601 E. 12th Street, 
    Kansas City, Missouri 64106.
    
    Discussion
    
        The FAA has received reports of four icing-related occurrences (one 
    incident and three fatal accidents) involving Beech Models 60 and A60 
    airplanes. Investigation of these occurrences revealed that, in two of 
    the accidents, the airplane was traveling too slow for icing 
    conditions.
        The Model 60 and A60 Pilot's Operating Handbook/Airplane Flight 
    Manual (POH/AFM), including the FAA-approved sections, contains no 
    specification or precautionary performance advisory regarding the 
    appropriate minimum airspeed to maintain while operating in icing 
    conditions.
        Beech recently issued AFM supplement ``FLIGHT IN KNOWN ICING 
    CONDITIONS'', Revised: January 1995, part number (P/N) 60-590001-17. 
    This AFM supplement establishes a minimum airspeed for operating Beech 
    Models 60 and A60 airplanes in icing conditions.
        After examining the circumstances and reviewing all available 
    information related to the incidents described above, the FAA has 
    determined that AD action should be taken to prevent loss of control of 
    the airplane because of the airplane traveling too slow in icing 
    conditions.
        Since an unsafe condition has been identified that is likely to 
    exist or develop in other Beech Models 60 and A60 airplanes of the same 
    type design, the proposed AD would require incorporating AFM supplement 
    ``FLIGHT IN KNOWN ICING CONDITIONS'', Revised: January 1995, part 
    number (P/N) 60-590001-17, into the applicable AFM.
        The compliance time of the proposed AD is presented in calendar 
    time instead of hours time-in-service. Although the unsafe condition 
    develops as a result of airplane usage, it cannot develop unless the 
    airplane travels too slow in icing conditions. Therefore, to ensure 
    that all owners/operators of the affected airplanes incorporate the 
    minimum airspeed in icing conditions flight manual supplement revisions 
    in a reasonable amount of time, a compliance based on calendar time is 
    proposed.
        The FAA estimates that 243 airplanes in the U.S. registry would be 
    affected by the proposed AD, that it would take less than 1 workhour 
    per airplane to accomplish the proposed action. Since an owner/operator 
    who holds a private pilot's certificate as authorized by sections 43.7 
    and 43.11 of the Federal Aviation Regulations (14 CFR 43.7 and 43.11) 
    can accomplish this action, the [[Page 29514]] only cost impact upon 
    the public is the time it takes to incorporate these AFM supplement 
    revisions.
        The regulations proposed 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 
    proposal would 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) if promulgated, 
    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 draft regulatory evaluation 
    prepared for this action has been placed in the Rules Docket. A copy of 
    it may be obtained by contacting the Rules Docket at the location 
    provided under the caption ADDRESSES.

    The Proposed 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. 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 AD to read as follows:
    
    Beech Aircraft Corporation: Docket No. 95-CE-23-AD.
    
        Applicability: Models 60 and A60 airplanes, serial numbers P-4 
    through P-246, 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 use the authority 
    provided in paragraph (d) of this AD 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 airplane from the applicability of this AD.
    
        Compliance: Required within the next 60 calendar days after the 
    effective date of this AD, unless already accomplished.
        To prevent loss of control of the airplane because of the 
    airplane traveling too slow in icing conditions, accomplish the 
    following:
        (a) Incorporate Airplane Flight Manual (AFM) supplement ``FLIGHT 
    IN KNOWN ICING CONDITIONS'', Revised: January 1995, part number (P/
    N) 60-590001-17, into the AFM, P/N 60-590000-5 or P/N 60--590000-11, 
    as applicable.
        (b) Incorporating the AFM supplement ``FLIGHT IN KNOWN ICING 
    CONDITIONS'', Revised: January 1995, part number (P/N) 60-590001-17, 
    as required by this AD may be performed by the owner/operator 
    holding at least a private pilot certificate as authorized by 
    section 43.7 of the Federal Aviation Regulations (14 CFR 43.7), and 
    must be entered into the aircraft records showing compliance with 
    this AD in accordance with section 43.11 of the Federal Aviation 
    Regulations (14 CFR 43.11).
        (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) An alternative method of compliance or adjustment of the 
    compliance time that provides an equivalent level of safety may be 
    approved by the Manager, Wichita Aircraft Certification Office 
    (ACO), FAA, 1801 Airport Road, Room 100, Wichita, Kansas 67209. The 
    request should be forwarded through an appropriate FAA Maintenance 
    Inspector, who may add comments and send it to the Manager, Wichita 
    ACO.
    
        Note 2: Information concerning the existence of approved 
    alternative methods of compliance with this AD, if any, may be 
    obtained from the Wichita ACO.
    
        (e) All persons affected by this directive may obtain copies of 
    the AFM revision referred to herein upon request to Beech Aircraft 
    Corporation, P.O. Box 85, Wichita, Kansas 67201-0085; or may examine 
    these documents at the FAA, Central Region, Office of the Assistant 
    Chief Counsel, Room 1558, 601 E. 12th Street, Kansas City, Missouri 
    64106.
    
        Issued in Kansas City, Missouri, on May 26, 1995.
