MIA APCH CTL PREVENTED AN ACR LGT FROM LNDG AT OPF.

Narrative

WE WERE AT 3000 FT MSL BEING VECTORED FOR A VISUAL APCH TO MIA RWY 27R. OUR POS WAS 5-10 NM NNE OF MIA ARPT; HEADED 180 DEGS. IT WAS A CLR NIGHT WITH AN ABUNDANCE OF GND LIGHTS FILLING THE WINDSHIELD. I WAS DIVIDING MY SCAN BTWN THE PANEL AND OUTSIDE; TRYING TO PICK UP MIA RWY 27R VISUALLY. AT SOME POINT AS I HAD STARTED REDUCING SPD FURTHER; IN ANTICIPATION OF A R HAND TURN TO FINAL; WE BOTH SPOTTED A BRIGHTLY LIT RWY WITH THE PROPER ORIENTATION TO US. MY IMMEDIATE REACTION WAS THAT I WAS HIGH; FAST; AND TIGHT. THERE WAS ONLY TIME TO 'SLAM DUNK' IN A HARD R TURN; SO MY FULL ATTN WENT TO FLAP SPDS; TURNING; DSNDING; AND NOT OVERSHOOTING. I NEVER THOUGHT OR HAD TIME TO CHK THE INSTS AT THAT POINT. ON FINAL; MIA CALLED AND TOLD US TO CLB STRAIGHT AHEAD TO 3000 FT; THEN TURN N. I WAS SHOCKED; TO SAY THE LEAST! THEY MENTIONED OPA LOCKA ARPT IN THEIR INSTRUCTIONS. I BLAME THIS INCIDENT ON SEVERAL THINGS. IT WAS MY FIRST LEG AFTER 10 DAYS OFF (NOT WARMED UP!); LATE NIGHT FLYING AND DIFFICULTY SPOTTING MIA ARPT IN ALL THE LIGHTS; FIRST FLT WITH THIS FO (NOT FULLY FORMED AS A CREW YET); AND MY FAILURE TO DO A FINAL CHK ON MY FMS DISPLAY/ILS WHICH WAS SET PROPERLY.
