Also I am at a 141 school. Does my annual 141 check count as a flight review?
Not unless you say, "hey dude, do you want to make this last for an hour and you sign my log book as a BFR at the same time..."
Since you are a current flight instructor and if and only if that certificate has been renewed at least once, you can forgo the hour of ground requirement via this reg.
61.56 (f) A person who holds a current flight instructor certificate who has, within the period specified in paragraph (c) of this section, satisfactorily completed a renewal of a flight instructor certificate under the provisions in §61.197 need not accomplish the 1 hour of ground training specified in paragraph (a) of this section.
Otherwise no, 141 school do not have an auto-BFR ability.
and
61.56 (d) (d) A person who has, within the period specified in paragraph (c) of this section, passed a
pilot proficiency check conducted by an examiner, an approved pilot check airman, or a U.S. Armed Force, for a
pilot certificate, rating, or operating privilege need not accomplish the flight review required by this section.
This one is a common mistake, but this is the reg that tells us we can not count our CFI check rides as a BFR, because it is not a pilot certificate. Like the other guy said, you can ask for a BFR at the same time though.
EDIT: sorry for sounding grumpy, I just got out of the movie Australia, it was honestly one of the worst movies I have seen in a while, and unfortunately, one of the longest too.
