From a statement in slot just above:
"... cite sentences ... in a letter from an official in the FAA’s Flight Standards Service ... the reference(s) ..."
The ref # used by FAA for that reply-letter is "reference:
S20070716012":
Letter from FAA, John M. Allen, Deputy Director,[AFS-2], Flight Standards Service, Reply Dated Jan 2nd, 2008. Letter was 2-pages; one important paragraph is the last paragraph on the first page:
“In its review of these complaints, Flight Standards Southwest Region determined that ... the term “stabilized thrust” ... has the same meaning as engines spooled up and can be used ....”
Edit: FAA's website shows that the
writer [FAA, John M. Allen, Deputy Director,[AFS-2], Flight Standards Service] was later PROMOTED to AFS-1, and as of Feb'09 that man is listed as "John Allen, Director, Flight Standards Service"
