    SUMMARY: This notice announces the availability of, and requests 
    comments on, a proposed Technical Standard Order (TSO) pertaining to 
    minimum performance standards and fire resistance standards that hose 
    assemblies, commonly used in aerospace fuel, engine oil, and hydraulic 
    fluid systems, must meet to be identified with the TSO-C140 marking.
    
    DATES: Comments must be received on or before March 31, 2000.

    SUPPLEMENTARY INFORMATION:
    
    Comments Invited
    
        Interested persons are invited to comment on the proposed TSO 
    listed in this notice by submitting such written data, views, or 
    arguments, as they desire to the address specified. Comments received 
    on the proposed Technical Standard Order may be examined, before and 
    after the comment closing date, in ARB Room 304A, Mike Monroney 
    Aeronautical Center, 6500 S. MacArthur Boulevard, Oklahoma City, OK 
    73169, weekdays, except Federal holidays, between 8:00 a.m. and 4:00 
    p.m. All communications received on or before the closing date for 
    comments specified above will be considered by the Director of the 
    Aircraft Certification Service before issuing the final TSO.
    
    Background
    
        Current TSO-C53a, ``Fuel and Engine Oil System Hose Assemblies,'' 
    and TSO-C75, ``Hydraulic Hose Assemblies,'' were issued in the early 
    1960s and have not been updated or revised to reflect the use of new 
    materials and manufacturing methods. Proposed TSO-C140 would clearly 
    define and identify improved materials and hose designs that would 
    satisfy the service parameters for flexible hose assemblies used in 
    current aviation applications. The standards of TSO-C140 would apply to 
    any model of aerospace fuel, engine oil, or hydraulic fluid hose 
    assembly for which a TSO application is submitted after the effective 
    date of the TSO.
        Revision B of the Society of Automotive Engineers, Inc. (SAE) 
    Aerospace Standard Document No. 150 (AS150 REV B), ``Hose Assembly, 
    Type Classifications of, Basic Performance and Fire Resistance,'' is 
    referenced in proposed TSO-C140 to establish performance standards and 
    test conditions for hose assemblies. Representative samples of fire 
    resistant and fireproof hose assemblies would be required to meet the 
    test conditions specified in SAE AS1055 REV D, ``Fire Testing of 
    Flexible Hose, Tube Assemblies, Coils, Fittings, and Similar System 
    Components.''
        Hose assemblies currently approved under a TSO-C53a or TSO-C75 
    authorization could continue to be manufactured under the provisions of 
    their original approval. Per 14 CFR Sec. 21.611(b), any major design 
    change to a hose assembly previously approved under TSO-C53a or TSO-C75 
    would require a new authorization under the proposed TSO.
    
    How to Obtain Copies
    
        A copy of the proposed TSO-C140 may be electronically obtained via 
    the Internet (http:/www.faa.gov/avr/air/air100/100home.htm) or 
    requested from the FAA office listed under For Further Information 
    Contact. Copies of AS150 REV B, AS1055 REV D, and other SAE documents 
    referenced in AS150 REV B may be purchased by mail from the Society of 
    Automotive Engineers Inc., 400 Commonwealth Drive, Warrendale, PA
