    THREADS IAW FED STD H28A ???

    Our engineering drawings state "THREADS IAW FED STD H28A" in the tolerance block. My question is... WHY?

    Change Authorization Documents

    Our current practice is to have the Drafter/Designer electronically add ALL signatures and dates (even for a new release) after the ECO is approved. There is nothing stopping them from making last minute edits (intentional or not). Then they create a PDF and publish the drawing. My strong...
