PLT OVERSHOT TURN TO FINAL ON PARALLEL APCH AND INTRUDED ON ADJACENT ARR.

Narrative

ON NOV/XA/94 I WAS OCCUPYING THE R SEAT OF A B-737; AS CHK CAPT; ON AN FAA PROVING RUN FOR MY COMPANY. 4 PEOPLE WERE IN THE COCKPIT; CAPT IN L SEAT; MYSELF IN R; COMPANY JUMPSEAT PLT RECEIVING IOE AND AN FAA ACR INSPECTOR IN THE AFT JUMPSEAT. WE WERE INBOUND TO DEN; RECEIVING RADAR VECTORS FOR A VISUAL; PARALLEL APCH TO RWY 26R. PARALLEL TFC TO RWY 26L WAS AN ACR X B-727. I HAD BRIEFED THE CAPT DURING DSCNT THAT WE WOULD: 1) TURN ON TO FINAL FROM THE N; 2) ABSOLUTELY NOT TO OVERSHOOT FINAL; AND 3) TO APCH RWY CTRLINE FROM AN OBLIQUE ANGLE SLIGHTLY N OF CTRLINE. ON BASE LEG; PARALLEL TFC WAS POINTED OUT BY APCH. THE CAPT AND COMPANY JUMPSEAT RIDER SAW ACR X. ACR X ACKNOWLEDGED SEEING US. WE WERE CLRED FOR THE VISUAL RWY 26R. DURING OUR R TURN TO FINAL THE TCASII ANNOUNCED A TA FOLLOWED QUICKLY BY AN RA. 3 THINGS HAPPENED QUICKLY: 1) THE RA COMMANDED A CLB; 2) I COMMANDED A CLB AND A R TURN TOWARDS THE RWY; AND 3) THE FAA INSPECTOR SCREAMED 'CLB THE EXPLETIVE ACFT' OR WORDS TO THAT EFFECT. HE CAME FORWARD; OUT OF HIS SEAT AS FAR AS THE SEAT BELT WOULD ALLOW. ALTHOUGH STARTLED; THE CAPT IMMEDIATELY APPLIED PWR; CLBED; AND TURNED TOWARD THE RWY. UPON LEVEL OUT; ACR X WAS SLIGHTLY AHEAD; APPROX 500 FT BELOW AND TO OUR L. AT THIS POINT WE WERE SLIGHTLY S OF CTRLINE. AT APPROX 2000 FT AGL AND 5-6 MI FROM RWY; I TOLD CAPT TO INTERCEPT CTRLINE; HE DID AND WE LANDED UNEVENTFULLY. NEITHER ACR X NOR THE TWR MENTIONED ANYTHING ABOUT THE CLOSENESS OF THE TFC OR A TCASII MESSAGE. WITH APPROX 800 FT SEPARATING THESE RWYS; ALL VISUAL APCHS ARE CLOSE. UPON ARR AT THE GATE; THE FAA INSPECTOR EXITED THE COCKPIT AND ANNOUNCED TO THE FLT ATTENDANTS AND FAA PERSONNEL ON BOARD THAT; 'THAT DUMB S.O.B. CAPT ALMOST GOT US KILLED IN A MIDAIR.' CONTRIBUTING FACTORS: 1) THE TCASII WHICH WAS IN 'TA/RA' SHOULD HAVE BEEN PLACED IN TA WHEN VISUAL WITH ACR X. 2) THE FAA'S RESPONSE WAS INAPPROPRIATE AND UNPROFESSIONAL. HE PHYSICALLY COULD NOT SEE THE TFC. HIS SCREAM DELAYED THE CAPT'S RESPONSE BECAUSE OF THE SHOCK. CORRECTIVE ACTION: DENVER SHOULD STAGGER THE TFC INBOUND TO RWY 26L/R. WITH LESS THAN STANDARD RWY SEPARATION; THE POTENTIAL IS TOO GREAT FOR CONFLICT.
