FLT CREW OF FA20 LANDED AT DEST WITH LESS THAN FAA RESERVE FUEL ON BOARD.

Narrative

THE FLT WAS ORIGINALLY PLANNED FROM MIA TO TRI TO REFUEL FOR FOLLOW-ON FLT FROM TRI TO YIP. PRIOR TO DSCNT INTO TRI; THE CREW EVALUATED FUEL CAPACITY FOR A NON-STOP FLT DIRECTLY TO YIP. THE CREW ESTIMATED A 4000 LB FUEL REQUIREMENT TO FLY NON STOP TO YIP. WITH 6000 LBS OF FUEL ON BOARD; THE CREW ELECTED TO OVERFLY TRI AND FLY NON-STOP TO YIP. OVER DQN VOR; THE CREW REQUESTED ATC TO ALLOW CONTINUED FLT AT ALT (FL350) FOR AS LONG AS POSSIBLE TO PREVENT BECOMING FUEL CRITICAL. ATC ACCOMMODATED THE FLT AS LONG AS POSSIBLE AND GAVE AS MANY DIRECT VECTORS AS POSSIBLE FOR THE OPERATIONAL SIT. BY THE TIME THE FLT REACHED CRUXX INTXN AT 9000 FT MSL AT 250 KTS IN ICING CONDITIONS; THE FUEL ON BOARD WAS 1700 LBS. DUE TO WX CONDITIONS; ATC VECTORING; AND REQUIRED ACFT CONFIGN; THE FLT ULTIMATELY TERMINATED SAFELY AT YIP; BUT WITH CONSIDERABLY LESS THAN REQUIRED FUEL RESERVES (APPROX 375 LBS). HAD A GAR OR DIVERT TO ALTERNATE BEEN REQUIRED; THERE WERE INSUFFICIENT FUEL RESERVES AVAILABLE. MITIGATING FACTORS TO THIS EVENT WERE WX; ATC REQUIREMENTS; AND FUEL FLOW REQUIREMENTS FOR ANTI-ICE OPS.
