FAILED TO PROGRAM INS PER CLRNC ROUTING.

Narrative

THE FLT WAS A SCHEDULED NIGHT FLT NONSTOP FROM BRUSSELS; BELGIUM (EBBR); TO EWR. DURING THE PREFLT OPS THE F/O LOADED THE FILED ROUTE; AS LISTED ON THE FLT RELEASE; INTO ALL 3 INS UNITS. AFTER DEPARTING BRUSSELS WE CALLED SHANWICK RADIO TO GET OUR OCEANIC CLRNC FOR THE XING. THEY COULD NOT FIND OUR FLT PLAN; SO THEY ASKED US WHAT OUR FILED ROUTE WAS. THE F/O READ THE ROUTE THAT WAS ON THE FLT RELEASE; AND PROGRAMMED INTO THE INS'S. WHEN THE CTLR FINALLY CAME BACK WITH OUR CLRNC THE FULL ROUTE WAS READ. IT WAS THE SAME AS FILED; EXCEPT THAT IT WENT TO A DIFFERENT ENTRY POINT INTO CANADA. AFTER 54 DEGS N; 50 DEGS W; WE WERE CLRED TO 'CARPE; REDBY; FLT PLAN ROUTE TO KEWR;' INSTEAD OF 54 DEGS N; 50 DEGS W; DOTTY; FLT PLAN ROUTE TO KEWR. 2 READBACKS WERE REQUIRED BEFORE THE F/O AND THE CTLR WERE SATISFIED OF THE ROUTE CLRED. THE F/O ENTERED THE NEW ROUTING AFTER 54 DEGS N; 50 DEGS W INTO THE #2 AND #3 INS UNITS. THE CAPT WAS; AT THAT TIME; WORKING ON HIS INS (#1); SO THE F/O ASSUMED THAT HE WAS ENTERING THE AMENDED ROUTE INTO THE #1 INS. THE CAPT ASSUMED THAT THE F/O HAD ENTERED THE NEW ROUTING; AS PER COMPANY PROCS; HOWEVER THE #1 INS WAS NEVER AMENDED. THE FLT WENT NORMAL ACROSS THE OCEAN WITH PERIODIC CHKS OF POS ON ALL 3 INS'S SHOWING US RIGHT ON COURSE. THE CAPT WAS FLYING THIS LEG; WITH THE #1 AUTOPLT TIED TO THE #1 INS. BY OUR COMPANY FLT OPS MANUAL THE 3 INS UNITS WERE SET UP TO PROVIDE PRESENT POS ON THE CAPT'S INS; ETA TO THE NEXT WAYPOINT ON THE F/O'S INS; AND WIND READOUT ON THE S/O'S INS WHILE USING THE #1 INS FOR NAV. AT 54 DEGS N; 50 DEGS W; THE F/O HAD A GREAT DEAL OF TROUBLE COMMUNICATING WITH GANDER ON THE HF RADIO. PERHAPS BECAUSE OF THE ACCURACY OF THE 3 INS'S UP TO THAT POINT; OR BECAUSE WE WERE BACK ALMOST OVER LAND; OR BECAUSE OF THE LATE NIGHT HR; NO ONE CONFIRMED THE NEXT FLT SEGMENT. THE AUTOPLT; BEING TIED TO THE #1 INS; TURNED AND BEGAN TRACKING TO DOTTY INSTEAD OF THE CLRED ROUTE OVER CARPE. AFTER THE POS RPT WAS FINALLY GIVEN THE F/O NOTICED THE #2 HSI WAS SHOWING A CROSSTRACK ERROR; WHICH I CONFIRMED ON THE #3 INS. THE CAPT'S HSI WAS CENTERED AND UPON XCHKING THE 3 INS'S WE DISCOVERED THE INCORRECT WAYPOINT IN THE #1 INS. WE IMMEDIATELY CALLED GANDER ON THE VHF RADIO (FIRST CONTACT) AND TOLD THEM WE WERE S OF COURSE. AFTER AN IDENT WAS RECEIVED FROM OUR TRANSPONDER; HE SAID WE WERE IN RADAR CONTACT AND CLRED US 'DIRECT TO ALBANY; FLT PLAN ROUTE; MAINTAIN FL310.' APPARENTLY THERE WERE NO OTHER ACFT IN OUR AREA. THE FLT PROCEEDED TO EWR WITH NO OTHER PROBS.
