arguments as they desire to the above specified address. Comments 
received on the proposed technical standard order may be examined, 
before and after the comment closing date, in Room 815, FAA 
Headquarters Building (FOB-10A), 800 Independence Avenue, SW., 
Washington, DC 20591, weekdays except Federal holidays, between 8:30

Background

    The FAA established the Aviation Rulemaking Advisory Committee 
(ARAC) in January 1991 to provide an ongoing mechanism to accept 
recommendations from the aviation industry in the regulatory process 
(56 FR 2190; January 22, 1991; and 58 FR 9230; February 19, 1993). In 
March 1993, the FAA established the Parts Working Group as part of ARAC 
(58 FR 16572; March 29, 1993). The Parts Working Group was tasked with 
recommending to ARAC new regulations and guidance material, as 
appropriate, pertaining to the issuance and administration of approvals 
of replacement and modification parts for civil aircraft. The proposed 
TSO in this notice is based on a draft proposed TSO developed by the 
Parts Working Group and recommended to the FAA by the ARAC.
    The standards of proposed TSO-C148 apply to types of mechanical 
fasteners intended for tension and/or shear applications in the 
manufacture and maintenance of aircraft products. The standards are 
also adaptable to fasteners of proprietary designs. Proposed TSO-C148 
provides alternative requirements for marking each individual fastener 
in lieu of the marking specified by 14 CFR Sec. 21.607(d).

How To Obtain Copies

    A copy of the proposed TSO-C148 may be obtained by contacting FOR 
FURTHER INFORMATION CONTACT.

    Issued in Washington, DC, on February 26, 1997.

Service.
