DATES: Comments must identify the TSO file number and be received on or 
before January 5, 1998.

ADDRESSES: Send all comments on the proposed technical standard order 
to: Technical Programs and Continued Airworthiness Branch, AIR-120, 
Aircraft Engineering Division, Aircraft Certification Service--File No. 
TSO-C149, Federal Aviation Administration, 800 Independence Avenue, 
SW., Washington, DC 20591. Or deliver comments to: Federal Aviation 
Administration, Room 815, 800 Independence Avenue, SW., Washington, DC

Comments Invited

    Interested persons are invited to comment on the proposed TSO

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 or proposed TSO-C149 apply to aircraft bearings 
intended for anti-friction rotation and/or oscillatory applications in 
the manufacture and maintenance of aircraft products. Proposed TSO-C149 
provides alternative requirements for making each individual bearing. 
Each bearing 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 lubrication date (if applicable), and 
the manufacturer's inspection lot number shall be marked on each 
package and container.

How to Obtain Copies

    A copy of the proposed TSO-C149 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 27, 1997.
