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.
