Narrative:

12/88 flight mco-ewr. After takeoff departure cleared us to turn left and climb to 12000'. We rolled out around 7000' in our climb, and an small aircraft, single engine, filled up my windscreen. We were passing through 7250' when we started our evasive action to our right. Departure did not have control of this aircraft, and he was in the cone of confusion (antenna) for departure to see. Air carrier Y airline behind leveled off at 6000' and observed this small aircraft around 7500'. After this aircraft left the airport area, he turned on his mode C and he was at 7600', according to departure control. I think small aircraft's should always file a clearance and talk to controling agents at all times. This guy could have had 2 near misses within 1 min if air carrier Y had not leveled off on its on.

Title: CLOSE PROX ACR-MLG GA-SMA.

Narrative: 12/88 FLT MCO-EWR. AFTER TKOF DEP CLRED US TO TURN LEFT AND CLB TO 12000'. WE ROLLED OUT AROUND 7000' IN OUR CLB, AND AN SMA, SINGLE ENG, FILLED UP MY WINDSCREEN. WE WERE PASSING THROUGH 7250' WHEN WE STARTED OUR EVASIVE ACTION TO OUR RIGHT. DEP DID NOT HAVE CTL OF THIS ACFT, AND HE WAS IN THE CONE OF CONFUSION (ANTENNA) FOR DEP TO SEE. ACR Y AIRLINE BEHIND LEVELED OFF AT 6000' AND OBSERVED THIS SMA AROUND 7500'. AFTER THIS ACFT LEFT THE ARPT AREA, HE TURNED ON HIS MODE C AND HE WAS AT 7600', ACCORDING TO DEP CTL. I THINK SMA'S SHOULD ALWAYS FILE A CLRNC AND TALK TO CTLING AGENTS AT ALL TIMES. THIS GUY COULD HAVE HAD 2 NEAR MISSES WITHIN 1 MIN IF ACR Y HAD NOT LEVELED OFF ON ITS ON.
