An air carrier flight crew conducting a visual approach initiated evasive action turn away from an MD80 making a visual approach to a parallel runway. The MD80's flight path slid into the other aircraft's flight course as the MD80 turned from base to final. TRACON supervisor discussed the incident with the evading aircraft captain saying ATC had problems with the conflicting MD80 flight crew.

Narrative:
Traffic congestion and radio frequency instructions were heavy. The visual approach system appeared congested and functioning at capacity (very fast paced). Our aircraft was on assigned heading and 180 KTS, descending from 5000 ft to 4000 ft on a base to final for a visual approach to runway 8L. An MD80, being vectored for a 'freeway visual runway 8R' from the south, overshot his pattern so as to fly a ground track that overshoots the runway 8L extended centerline. Evasive action was taken initially as we passed laterally (as he overshot) and then again as we configured to keep from overrunning his aircraft while he was maneuvering away from the runway 8L extended final. Our aircraft appeared to land simultaneously on the parallel runway. We were asked by approach control to contact them by telephone. The other aircraft captain, apparently did not. The supervisor on duty apologized to me for the confusion and conflict and mentioned that throughout the arrival, the MD80 was slow to acknowledge and slow to maneuver.
Original NASA ASRS Text
Title: AN ACR FLC CONDUCTING A VISUAL APCH INITIATED EVASIVE ACTION TURN AWAY FROM AN MD80 MAKING A VISUAL APCH TO A PARALLEL RWY. THE MD80'S FLT PATH SLID INTO THE OTHER ACFT'S FLT COURSE AS THE MD80 TURNED FROM BASE TO FINAL. TRACON SUPVR DISCUSSED THE INCIDENT WITH THE EVADING ACFT CAPT SAYING ATC HAD PROBS WITH THE CONFLICTING MD80 FLC.
Narrative: TFC CONGESTION AND RADIO FREQ INSTRUCTIONS WERE HVY. THE VISUAL APCH SYS APPEARED CONGESTED AND FUNCTIONING AT CAPACITY (VERY FAST PACED). OUR ACFT WAS ON ASSIGNED HEADING AND 180 KTS, DSNDING FROM 5000 FT TO 4000 FT ON A BASE TO FINAL FOR A VISUAL APCH TO RWY 8L. AN MD80, BEING VECTORED FOR A 'FREEWAY VISUAL RWY 8R' FROM THE S, OVERSHOT HIS PATTERN SO AS TO FLY A GND TRACK THAT OVERSHOOTS THE RWY 8L EXTENDED CTRLINE. EVASIVE ACTION WAS TAKEN INITIALLY AS WE PASSED LATERALLY (AS HE OVERSHOT) AND THEN AGAIN AS WE CONFIGURED TO KEEP FROM OVERRUNNING HIS ACFT WHILE HE WAS MANEUVERING AWAY FROM THE RWY 8L EXTENDED FINAL. OUR ACFT APPEARED TO LAND SIMULTANEOUSLY ON THE PARALLEL RWY. WE WERE ASKED BY APCH CTL TO CONTACT THEM BY TELEPHONE. THE OTHER ACFT CAPT, APPARENTLY DID NOT. THE SUPVR ON DUTY APOLOGIZED TO ME FOR THE CONFUSION AND CONFLICT AND MENTIONED THAT THROUGHOUT THE ARR, THE MD80 WAS SLOW TO ACKNOWLEDGE AND SLOW TO MANEUVER.
