ON APCH INTO THE HOME-BASE ARPT; AN AIR AMBULANCE FLC FAILED TO CONTACT THE TWR; AND THUS; LANDED WITHOUT A CLRNC TO LAND.

Narrative

I WAS CAPT; AS WELL AS 'PF;' WHEN WE WERE CLRED FOR THE ILS RWY 9L; AT FLL; BY MIAMI APCH. WE HAD FLOWN OVER 9.5 HRS; AND HAD JUST TRAVERSED AN AREA OF MODERATE CONVECTIVE ACTIVITY. AFTER BECOMING ESTABLISHED ON FINAL APCH; WE BOTH SPENT TIME XCHKING AND COMMENTING ON THE GS INDICATIONS; WHICH HAD DISAGREED MOMENTARILY; ON AN APCH; EARLIER IN THE DAY. THEY BOTH XCHKED GOOD AND WE CONTINUED THE APCH IN PREDOMINANTLY VFR CONDITIONS. WE WERE #1 FOR THE ARPT AND WE CONTINUED TO MONITOR APCH CTL AS THEY VECTORED 3 ACFT; BEHIND US. (I WOULD CLASSIFY THE AMOUNT OF TFC IN THE AREA AS 'LIGHT). WE COMPLETED THE 'BEFORE LNDG' CHKLIST; AND WERE IN FULL LNDG CONFIGN BY 1000 FT AGL. WE LANDED ON RWY 9L (NO OTHER ACFT WERE OBSERVED ON THE GND); WITHOUT REALIZING THAT WE HAD NEVER SPOKEN TO; OR RECEIVED LNDG CLRNC FROM FT LAUDERDALE TWR. IMMEDIATELY; AFTER LNDG; THE FO REALIZED THAT APCH CTL HAD NEVER HANDED US OFF TO TWR; AND WE FINALLY CALLED TWR; WHO INSTRUCTED US TO TAXI TO THE RAMP. NO OTHER COM WAS OFFERED. I BELIEVE THAT THE PRIMARY FACTOR WAS OUR FAILURE TO CHK FOR LNDG CLRNC; PRIOR TO CALLING FOR THE 'BEFORE LNDG CHKLIST COMPLETE.' LNDG CLRNC IS NOT 1 OF THE ITEMS ON OUR 'BEFORE LNDG' CHKLIST. A STRONG CONTRIBUTING FACTOR WAS MIAMI APCH CTL'S FAILURE TO CHANGE US OVER TO TWR FREQ. I INSTRUCTED THE FO TO ALWAYS SUFFIX THE 'BEFORE LNDG' CHKLIST WITH THE PHRASE 'CLRED TO LAND' OR 'AWAITING LNDG CLRNC;' AS DEEMED APPROPRIATE. HOPEFULLY THIS WILL PREVENT FUTURE INCIDENTS. SUPPLEMENTAL INFO FROM ACN 296730: I HAD BEEN ON DUTY 14 HRS WITH 9.6 HRS OF FLT. I THINK THE COMPLACENCY OF FLYING INTO OUR HOME BASE WITH EXCELLENT WX CONDITIONS LED TO THE PROB. LONG DAY (FATIGUE). FAILURE TO CHK '3 GREEN -- CLRED TO LAND' OVER THE FENCE.
