Background

    The failure condition specified in TSO-C44c, Paragraph 3.b., was 
incorrectly identified as ``hazardous.'' The proposed revision offered 
by this Federal Register Notice revises Paragraph 3.b. to state the 
following: ``Develop each fuel Flowmeter to at least the design 
assurance level equal to the failure condition classification of the 
system on which the Flowmeter is to be installed.'' The proposed draft 
changes no other MPS requirement of TSO-C44.
