Narrative:

Air carrier X northbound cleared to 4000 ft row runway 9R. Air carrier Y sbound at 5000 ft for runway 8L. X got RA to climb when he was 4 mi away at 5300 ft descending to 4000 ft. This caused him to level off at air carrier Y's altitude. The RA had instructed X to climb, prior to loosing 3 mi separation he was turned on final and cleared for a visual approach. I believe that had the pilot not been so concerned with TCASII and descended at a normal rate, he would have been at 4000 ft before he got close to final. In my opinion TCASII made this situation closer than it would have been!

Original NASA ASRS Text

Title: ACR X TCASII RA NON ADHERENCE TO ATC CLRNC HAD LTSS FROM ACR Y.

Narrative: ACR X NBOUND CLRED TO 4000 FT ROW RWY 9R. ACR Y SBOUND AT 5000 FT FOR RWY 8L. X GOT RA TO CLB WHEN HE WAS 4 MI AWAY AT 5300 FT DSNDING TO 4000 FT. THIS CAUSED HIM TO LEVEL OFF AT ACR Y'S ALT. THE RA HAD INSTRUCTED X TO CLB, PRIOR TO LOOSING 3 MI SEPARATION HE WAS TURNED ON FINAL AND CLRED FOR A VISUAL APCH. I BELIEVE THAT HAD THE PLT NOT BEEN SO CONCERNED WITH TCASII AND DSNDED AT A NORMAL RATE, HE WOULD HAVE BEEN AT 4000 FT BEFORE HE GOT CLOSE TO FINAL. IN MY OPINION TCASII MADE THIS SIT CLOSER THAN IT WOULD HAVE BEEN!
