Narrative:

Shortly after takeoff from mdw we had a near miss with a small high wing, single engine aircraft. We were level at 3000 ft on a 270 degree heading as assigned by ATC. The WX was clear and we were in smooth air. I was looking in the cockpit tuning in the #2 communication to company frequency. The first officer, who was the PF, made a comment 'we just had a near miss.' at the same time I felt the airplane bounce as if we flew in the small aircraft's wake. I called ATC and asked if he had an aircraft on radar near us. He said no, only 1 aircraft at our 12 O'clock position and about 5 mi. I told him we had a near miss. I never saw the aircraft. My first officer described to me the aircraft as a small, gray, hi-wing, 2-SEATER aircraft. He thought maybe an aeronca or cessna 150. The first officer was making a power adjustment when he looked up and saw the aircraft at the last second. We made no changes in our heading or altitude. My first officer said the small aircraft was in a 30 degree bank to the right. I think if we had TCASII we probably would have been warned ahead of time. I also recommend a higher altitude out of midway when going west. ATC usually keeps us at 3000 ft for quite a while when going west or northwest.

Original NASA ASRS Text

Title: NMAC.

Narrative: SHORTLY AFTER TKOF FROM MDW WE HAD A NEAR MISS WITH A SMALL HIGH WING, SINGLE ENG ACFT. WE WERE LEVEL AT 3000 FT ON A 270 DEG HDG AS ASSIGNED BY ATC. THE WX WAS CLR AND WE WERE IN SMOOTH AIR. I WAS LOOKING IN THE COCKPIT TUNING IN THE #2 COM TO COMPANY FREQ. THE FO, WHO WAS THE PF, MADE A COMMENT 'WE JUST HAD A NEAR MISS.' AT THE SAME TIME I FELT THE AIRPLANE BOUNCE AS IF WE FLEW IN THE SMALL ACFT'S WAKE. I CALLED ATC AND ASKED IF HE HAD AN ACFT ON RADAR NEAR US. HE SAID NO, ONLY 1 ACFT AT OUR 12 O'CLOCK POS AND ABOUT 5 MI. I TOLD HIM WE HAD A NEAR MISS. I NEVER SAW THE ACFT. MY FO DESCRIBED TO ME THE ACFT AS A SMALL, GRAY, HI-WING, 2-SEATER ACFT. HE THOUGHT MAYBE AN AERONCA OR CESSNA 150. THE FO WAS MAKING A PWR ADJUSTMENT WHEN HE LOOKED UP AND SAW THE ACFT AT THE LAST SECOND. WE MADE NO CHANGES IN OUR HDG OR ALT. MY FO SAID THE SMALL ACFT WAS IN A 30 DEG BANK TO THE R. I THINK IF WE HAD TCASII WE PROBABLY WOULD HAVE BEEN WARNED AHEAD OF TIME. I ALSO RECOMMEND A HIGHER ALT OUT OF MIDWAY WHEN GOING W. ATC USUALLY KEEPS US AT 3000 FT FOR QUITE A WHILE WHEN GOING W OR NW.
