AN ACR LINED UP ON THE WRONG RWY.

Narrative

ACFT WAS ON AUTOPLT USING FMS NAV IN MD-11 ACFT. APCH CTL DIRECTED ACFT ON A HDG TO INTERCEPT THE RWY 5L LOC AT RCPT. FMS WAS PREVIOUSLY LOADED WITH DATA FOR A RWY 5L ILS. THE RWY 5L IDENTIFIER; ITIA; WAS TUNED AND IDENTED BY BOTH PLTS; AS BEING CORRECT FOR RWY 5L. THE CAPT HAD ALSO HAND TUNED THE ITIA/53 INTO THE NAV/RADIO PAGE OF THE FMS. ACFT INTERCEPTED LOC NORMALLY. APCH ALERTED CREW TO BEING SE OF COURSE. LOC NEEDLE SHOWED CTRED BUT LOC FREQ HAD AUTO-TUNED TO ICKS; THE LOC FREQ FOR ILS-DME RWY 6; WITHOUT THE PLT'S KNOWLEDGE NOR THROUGH EITHER PLT'S ACTIONS. RECEIVED VECTOR TO INTERCEPT RWY 5L LOC AND LANDED WITHOUT FURTHER INCIDENT. CAPT ON THIS FLT HAD NOT SEEN ANYTHING OF THIS KIND IN HIS 4 YRS EXPERIENCE ON THE MD-11. I SUGGEST A FAIL-SAFE MODE WITH REQUIRED HAND TUNING OF ILS FREQS BE WRITTEN INTO THE FMS PROGRAMMING TO ENSURE THAT AUTO-TUNING NOT OCCUR IN THIS CRITICAL PHASE OF FLT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTING FO GLANCED DOWN AT THE FMS AND ASSURED THAT THE PROPER ILS HAD AUTO-TUNED AS PART OF HIS APCH PROC. HE DOES NOT KNOW IF THE CAPT RETUNED THE ILS MANUALLY; AND PUT IN THE WRONG ILS; OR WHETHER THE FMS JUMPED TO THE WRONG ILS BY ITSELF. THE RPTR IS RELATIVELY NEW TO THE MD-11 AND HAS NOT HEARD OF THIS TYPE OCCURRENCE BEFORE. THE CAPT DID NOT ADMIT THAT HE HAD MISTUNED THE ILS. IF THE ILS FREQ IS TYPED INTO THE FMS; THE FMS READS THE MORSE CODE IDENTIFIER AND WRITES IT ONTO THE FMS 'NAV RADIO' PAGE. THE CAPT; THE PNF; WAS A CHK AIRMAN. THE RPTING FO KNOWS THAT HE DID NOT AURALLY CHK THE ILS IDENTIFIER AND HE BELIEVES THAT THE CAPT PROBABLY DID NOT EITHER.
