Narrative:
Our flight air carrier xyyz was flying assigned heading towards ILS runway 18R final approach course, but we had not been cleared to intercept. As we were crossing runway 18R ILS final approach course, the controller questioned company air carrier xwyz about his heading. He said he had been cleared ILS runway 18R. (Because of the frequency (126.7) congestion we were unable to communicate.) the controller then stated that the approach clearance was for us (air carrier xyyz) which was not the case. We were never given an approach clearance to runway 18R.
Original NASA ASRS Text
Title: 2 DC10 CARGO ACFT WITH SIMILAR CALL SIGNS WERE GIVEN APCH CLRNC BY ATC TO THE WRONG ACFT CAUSING THE RPTR'S ACFT TO FLY THROUGH THE FINAL COURSE AND ALMOST THROUGH THE PARALLEL RWY.
Narrative: OUR FLT ACR XYYZ WAS FLYING ASSIGNED HDG TOWARDS ILS RWY 18R FINAL APCH COURSE, BUT WE HAD NOT BEEN CLRED TO INTERCEPT. AS WE WERE XING RWY 18R ILS FINAL APCH COURSE, THE CTLR QUESTIONED COMPANY ACR XWYZ ABOUT HIS HDG. HE SAID HE HAD BEEN CLRED ILS RWY 18R. (BECAUSE OF THE FREQ (126.7) CONGESTION WE WERE UNABLE TO COMMUNICATE.) THE CTLR THEN STATED THAT THE APCH CLRNC WAS FOR US (ACR XYYZ) WHICH WAS NOT THE CASE. WE WERE NEVER GIVEN AN APCH CLRNC TO RWY 18R.
