Documented history

Leading Chief or Line Chief or Engineering Chief

June 1945 is the manual’s publication date; no effective date for a transition is given.

  • The asterisk ties the references to 750 and 751 specifically to the June 1944 title; any reassignment required review of the individual’s qualifications against the job specifications.
  • “Line Chief, Aviation” is the June 1945 meaning of SSN 752, not a modern same-code equivalent.
Source extraction notes

Predecessor title from the June 1944 tentative-manual column: Leading Chief or Line Chief or Engineering Chief. Suggested conversions/remarks, as printed: *See also 750, 751. Asterisks bind the suggestions to the correspondingly marked earlier title, not to an unmarked present-title meaning. The Present Title column is the manual's June 1945 meaning: Line Chief, Aviation. It is not a present-day MOS equivalence. This is a cross-reference or instruction to review the job specification, not an explicit fixed replacement or proof of cancellation. The table gives no row-level calendar effective date. June 1945 is the manual publication date, not an inferred individual conversion date.
