Narrative:

Downwind runway 2L heading 200 degrees at 6000 ft. Clearance: turn left heading 110 degrees. Clearance: (voice change) heading 090 degrees. Clearance: slow, descend to 4000 ft. At 4000 ft TCASII RA 'traffic' climb. Started slow climb -- notified approach. He stated no traffic. Clear of traffic -- returned to 4000 ft. No idea if real or false. Clearance: left 030 degrees intercept localizer, clear for approach. In turn, armed land feature. At 030 degrees noticed we were well across localizer -- turned left to 340 degrees to recover. Said nothing to approach control. Approach control calls parallel 727 traffic -- had visual on traffic. Intercepted localizer and GS. Continued approach and landed, no problem. I believe the TCASII RA caught everyone off guard. At that point, positive control and attention waned. Outside of the TCASII RA and confusion, the cockpit was situationally aware and recovered in an acceptable manner.

Original NASA ASRS Text

Title: FLC OF AN MLG CLBED ABOVE ASSIGNED ALT AND CHANGED HDG IN RESPONSE TO A TCASII RA.

Narrative: DOWNWIND RWY 2L HDG 200 DEGS AT 6000 FT. CLRNC: TURN L HDG 110 DEGS. CLRNC: (VOICE CHANGE) HDG 090 DEGS. CLRNC: SLOW, DSND TO 4000 FT. AT 4000 FT TCASII RA 'TFC' CLB. STARTED SLOW CLB -- NOTIFIED APCH. HE STATED NO TFC. CLR OF TFC -- RETURNED TO 4000 FT. NO IDEA IF REAL OR FALSE. CLRNC: L 030 DEGS INTERCEPT LOC, CLR FOR APCH. IN TURN, ARMED LAND FEATURE. AT 030 DEGS NOTICED WE WERE WELL ACROSS LOC -- TURNED L TO 340 DEGS TO RECOVER. SAID NOTHING TO APCH CTL. APCH CTL CALLS PARALLEL 727 TFC -- HAD VISUAL ON TFC. INTERCEPTED LOC AND GS. CONTINUED APCH AND LANDED, NO PROB. I BELIEVE THE TCASII RA CAUGHT EVERYONE OFF GUARD. AT THAT POINT, POSITIVE CTL AND ATTN WANED. OUTSIDE OF THE TCASII RA AND CONFUSION, THE COCKPIT WAS SITUATIONALLY AWARE AND RECOVERED IN AN ACCEPTABLE MANNER.
