UNAUTHORIZED LNDG. NO CLRNC LNDG RECEIVED.

Narrative

ABOUT 12 MI OUT (ORD RWY 9R LOC) FLT WAS CLRED FOR ILS RWY 9R; MAINTAIN 4000 UNTIL CARLEY SPD 170 TO DEANA; CONTACT TWR AT DEANA 120.75. READ BACK AND DIALED IN TWR FREQ. AT THIS POINT; SOMETHING (I DON'T RECALL WHAT) DISTR ME. I MAY NOT HAVE COMPLETED ENTRY OF TWR FREQ. UPON RECEIVING OM SIGNAL AT DEANA; I CONTACTED TWR ON THE FREQ I HAD DIALED IN EARLIER: 'TWR; ACR X HVY INSIDE DEANA.' THE CTLR (A WOMAN) SAID SOMETHING TO SOMEONE ELSE; THEN SAID: 'WHO'S CALLING.' I REPLIED: 'ACR X HVY INSIDE DEANA.' THE CTLR REPLIED AND SAID 'CLRED TO LAND' TO SOMEONE; ALTHOUGH I MUST ADMIT I DID NOT HEAR TO WHOM THE CLRNC WAS ADDRESSED. I ASSUMED IT WAS US. ABOUT THIS TIME WE COMPLETED CONFIGURING FOR LNDG. THERE WAS SOME CONFUSION CONCERNING FINAL APCH 'BUG' SPD. I THOUGHT THE CAPT WAS SLOWING TOO MUCH; SO I RECHKED THE FIGURES AND INFORMED THE CAPT. WE GOT THE BUG CORRECTED; BUT THE COM IN THE COCKPIT WAS CONFUSING AND CONTRIBUTED TO MISINTERP OF WHAT WE HEARD ON THE RADIO. AS THE APCH CONTINUED; THE DISTRS CONTINUED AS THE LOC AND GS INDICATIONS BECAME ERRATIC. THE GPWS BEGAN TO ANNUNCIATE 'GS;' EVEN THOUGH; VISUALLY WE APPEARED TO BE VERY NEAR THE NORMAL GLIDE PATH AND THE LOC KEPT SWINGING BACK AND FORTH; THOUGH OUR COURSE WAS STEADY. IN ANY CASE; THERE WERE CONSTANT CONDITIONS REQUIRING ATTN THROUGHOUT THE APCH AND NO ONE VERIFIED THE LNDG CLRNC. AFTER LNDG; WE HEARD NOTHING FROM TWR DURING ROLLOUT; WHICH IS UNUSUAL AT ORD (THIS HAD ME WONDERING WHY; BUT IT WAS OBVIOUSLY NO TIME TO INVESTIGATE); UPON CLRING THE RWY; I CALLED GND CTL AND RECEIVED INSTRUCTIONS TO TAXI TO THE RAMP. THEN THE CTLR ASKED IF WE HAD COMMUNICATED WITH TWR. TO THIS I REPLIED; 'NEGATIVE' THINKING HE MEANT DURING ROLLOUT. I THEN AMENDED MY REPLY: 'WE CONTACTED TWR TWICE INSIDE DEANA AND WERE CLRED TO LAND; BUT WE HEARD NOTHING AFTER THAT.' THE CTLR REPLIED THAT TWR SAID THEY HEARD NOTHING FROM US. AT THIS TIME; WE ENTERED THE RAMP AREA AND THE FREQ WAS CHANGED AGAIN. IT WAS ONLY LATER THAT IT OCCURRED TO ME THAT I MIGHT HAVE DIALED THE WRONG FREQ AND; COINCIDENTALLY; CONTACTED SOME OTHER TWR CTLR. THEN; UPON HEARING SOMEONE CLRED TO LAND; ASSUMED IT TO HAVE BEEN WHAT I EXPECTED TO HEAR; WHICH WAS 'ACR X; CLRED TO LAND.' IT WAS; HOWEVER; IMPOSSIBLE TO VERIFY THIS; AS SEVERAL FREQ CHANGES HAD OCCURRED SINCE. CONTRIBUTING FACTORS: FATIGUE (BEING W COAST BASED; WE HAD ARISEN VERY EARLY IN THE EASTERN TIME ZONE TO FLY THIS LEG). COCKPIT DISTR (POOR INTRA-COCKPIT COMS; ERRATIC ILS INDICATIONS; BOGUS GPWS WARNING). LACK OF BACKUP (NO ONE IN THE COCKPIT WAS PAYING ANY ATTN TO THE RADIO; BUT ME AND I; APPARENTLY; WAS NOT PAYING IT ENOUGH). COMPLACENCY (THIS ROUTINE METHOD OF CONDUCTING APCHS IS USED SO OFTEN BY SCHEDULED CARRIER PLTS THAT WE BEGIN HEARING WHAT WE EXPECT TO HEAR RATHER THAN LISTEN TO WHAT IS ACTUALLY BEING SAID).
