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-C150 apply to aircraft seals intended 
for static and dynamic applications in the manufacture and maintenance 
of aircraft products. Proposed TSO-C150 provides alternative 
requirements for marking each individual seal. Each seal must be marked 
with at least the name or symbol of the manufacturer, the 
manufacturer's part number, and the TSO number. When this is not 
practical, marking may be accomplished in a manner approved by the 
Administrator. Also, in addition to the marking specified in 14 CFR 
607(d), the seal type, the manufacturer's inspection lot number, and 
the expected shelf life shall be marked on each package and container.

How To Obtain Copies

    A copy of the proposed TSO-C150 may be obtained via Internet 
(http:/www.faa.gov/avr/air/100home.htm) or on request from the office 
listed under FOR FURTHER INFORMATION CONTACT.

    Issued in Washington, DC, on October 29, 1997.
