FAA INSPECTOR CALLS CREW AT THEIR NEXT STOP TO INFORM THEY STARTED THEIR ENGS WITH A FUEL TRUCK PARKED BEHIND.

Narrative

THIS WAS A CORPORATE FLT FROM JAX TO OPF AND PICK UP PAX GOING TO CLT. NO FUELING WAS PLANNED AT OPF. UNFORECAST GND FOG FORCED A DIVERT TO MIA SO PAX DROVE TO THE OTHER ARPT (ALREADY BEHIND SCHEDULE). I WAS THE PNF FOR THE NEXT LEG FROM MIA TO CLT. MY CAPT MADE A PRUDENT DECISION TO ADD FUEL IN MIA DUE TO EXTENDED HOLDING BEFORE LNDG. FUEL TRUCK WAS POSITIONED BEHIND ACFT AND FUELING WAS COMPLETED AND FUEL CAPS LOCKED BY PLTS. I DID A QUICK WALK AROUND WHILE LOCKING CAPS AND SPENT NEXT 10 MINS OR SO GETTING IFR CLRNC FROM R SEAT. CAPT AND PAX BOARDED WHILE I FINISHED TKOF DATA AND WE STARTED ENGS AND DEPARTED AFTER MORE TFC DELAYS. UPON ARR AT CLT OUR DISPATCHER TOLD US THAT THE FAA HAD OBSERVED US STARTING AND RUNNING ENGS WITH THE FUEL TRUCK STILL BEHIND ACFT. IN OUR RUSH TO MAKE OUR PAX'S SCHEDULE WE HAD NEGLECTED TO CLR THE AREA. I HAD STARTED BOTH ENGS WITH THE FUEL TRUCK BEHIND US AND I ALSO HAD STARTED TAXIING AS THE CAPT WAS GETTING SEATED AND STRAPPING IN. ALTHOUGH OUR ORGANIZATION IS VERY SAFETY ORIENTED; WE HAD OVERLOOKED SOME VERY BASIC PRINCIPLES.
