## Discrepancy

DURING INITIAL CLIMB CREW RAN THE CLIMB CHECKLIST, AT THIS TIME FOUND THE A/C WAS NOT PRESSURIZING.  RAN FUEL NUMBERS AND DETERMINED THEY WOULD BE VERY CLOSE TO MIN FUEL WITH THE FUEL ON BOARD, DIVERTED BACK TO LIT WITHOUT FURTHER ISSUE.  EVALUATED & DEFERRED PER MX CONTROL IAW MEL 21-30-5-1 CAT A ID# 45713.  LATER PERFORMED OPS CHECK OF PRESSURIZATION SYSTEM IAW Q400 MM 21-31-00-946-002, OPS CHECKED GOOD.
