FLC LANDED AT WRONG ARPT AND THEN DEPARTED WITHOUT A DISPATCH RELEASE.

Narrative

THE PRIMARY FACTOR LEADING TO THE INCIDENT WAS THAT NEITHER CREW MEMBER HAD FLOWN THE RTE. THERE WERE NUMEROUS CONTRIBUTING FACTORS LEADING TO THE OUTCOME OF THE DAY. THE CAPT ATTEMPTED TO PLACE THE IATA IDENT INTO THE GPS AND FAILED. HE THEN TRIED THE NEAREST NAV FACILITY WHICH WAS FLP VOR AND THIS WAS ACCEPTED BY THE GPS. RWY FINALS TO BOTH FLP ARPT AND BPK ARPT ARE PARALLEL AND LONG FINAL TO BPK RUNS RIGHT OVER THE FLP ARPT. FROM THE BEGINNING; THE DAY WAS RUSHED AND ALWAYS BEHIND SCHEDULE. IT WAS SIMULTANEOUSLY DISCOVERED WHEN A NON REVENUE PAX APCHED THE FLC AND TOLD THEM OF THE CORRECT POS OF THE DEST ARPT. FLC DEPARTED FLP AND LANDED AT BPK WITHOUT INCIDENT OR ANY UNUSUAL CIRCUMSTANCES. FLC FAILED TO CONTACT OPS BEFORE DEPARTING FLP ARPT. SUPPLEMENTAL INFO FROM ACN 421400: THE CREW LANDED AT THE WRONG ARPT. INSTEAD OF TERMINATING THE FLT AND CONTACTING FLT OPS; THEY CHOSE TO TAKE OFF AGAIN AND LAND AT THE PROPER DEST ARPT; WHICH WAS 5.5 NM AWAY. AFTER LNDG AT THE PROPER DEST ARPT; THEY REALIZED THAT THEY HAD DEPARTED WITHOUT PROPER DISPATCH AUTH. IN DOING SO; THEY VIOLATED SEVERAL FARS. DURING THE CREW BRIEFING; THE CAPT STATED THAT THE GPS WAS SET UP TO GO TO FLP. I ASKED WHAT FLP WAS; AND HE REPLIED THAT IT WAS 'THE VOR NEAR THE ARPT.' I DID NOT CONSIDER HIS INABILITY TO GET THE GPS TO RECOGNIZE THE DEST ARPT AS SIGNIFICANT. I ASSUMED THAT SINCE THE WX WAS GOOD; THAT ONCE WE GOT CLOSE TO THE FLP VOR WE COULD GET A VISUAL APCH TO THE ARPT. 5-7 MI AWAY WAS THE LAST TIME I RECALL REFING THE GPS DURING THE FLT. WE CONTINUED THE DAY'S SCHEDULED FLTS WITHOUT NOTIFYING OPS.
