Narrative:

After takeoff we switched to departure control. TCASII was giving loud 'traffic' warnings making it hard to hear anything else in the cockpit. First warning I heard from departure control was 'traffic 11 O'clock, less than a mi'. We spotted small airplane moving left to right (heading about 260 degrees at 2100 ft). Our heading was 170 degrees. I took evasive action by increasing climb rate and turning to about 140 degrees. Our proximity at closest point was probably 200-400 ft as we passed through scattered clouds at 2200 ft. Other aircraft was level at 2100 ft and I'm not sure he ever saw us.

Original NASA ASRS Text

Title: CLOSE PROX ACR-LGT GA-SMA S OF HOU JUST AFTER TKOF.

Narrative: AFTER TKOF WE SWITCHED TO DEP CTL. TCASII WAS GIVING LOUD 'TFC' WARNINGS MAKING IT HARD TO HEAR ANYTHING ELSE IN THE COCKPIT. FIRST WARNING I HEARD FROM DEP CTL WAS 'TFC 11 O'CLOCK, LESS THAN A MI'. WE SPOTTED SMALL AIRPLANE MOVING L TO R (HDG ABOUT 260 DEGS AT 2100 FT). OUR HDG WAS 170 DEGS. I TOOK EVASIVE ACTION BY INCREASING CLB RATE AND TURNING TO ABOUT 140 DEGS. OUR PROX AT CLOSEST POINT WAS PROBABLY 200-400 FT AS WE PASSED THROUGH SCATTERED CLOUDS AT 2200 FT. OTHER ACFT WAS LEVEL AT 2100 FT AND I'M NOT SURE HE EVER SAW US.
