Narrative:

The pilot of commuter X reported a near midair collision with fgt Y. This fgt had made a low approach to runway 34 at ric. He made a missed approach and was assigned runway heading by east feeder. I was working the west feeder position when I received a roll check on aircraft X, an IFR departure. He was assigned heading 270 degrees climbing to 3000'. I cleared commuter X to 8000' on initial contact. I was told by the tower that fgt Y would be on runway heading off runway 34. I observed Y on departure go 6-7 mi northwest of ric heading 340 degrees and climb to 3000'. Fgt Y at 7 mi northwest squawked 1200 and started a left turn to the southeast and climbed quickly to 4500'. I told X to maintain 4000' and informed him of the traffic. These targets merged with X at 4000' and Y (now a 1200 squawk) at 4500.' as the targets cleared X was at 4000' and the VFR fgt Y was at 3700'. Aircraft X reported that he had to push the nose of his aircraft over and reported a near midair collision. Fgt Y in a later telephone conversation reported that he had aircraft X in sight. Fgt Y leaving his assigned frequency and making a VFR turn back toward the airport contributed to this problem developing. I believe Y, in fact, had X in sight and descended too close to him. Poor judgement by this pilot. Stricter attention to arsa requirements by fgt Y would have prevented this occurrence. Monitoring of 243.0 by fgt Y would have prevented this occurrence. There was some questions about IFR departure clearance for Y. Had an IFR been filed Y would have been under more positive control. The pilot of Y appears to have been in marginal WX as aircraft X reported 1/2 mi visibility and heavy snow.

Title: LESS THAN STANDARD SEPARATION AND NAMC BETWEEN COMMUTER AND MIL-FGT ACFT IN RIC ARSA. PLT DEVIATION.

Narrative: THE PLT OF COMMUTER X RPTED A NMAC WITH FGT Y. THIS FGT HAD MADE A LOW APCH TO RWY 34 AT RIC. HE MADE A MISSED APCH AND WAS ASSIGNED RWY HDG BY E FEEDER. I WAS WORKING THE W FEEDER POS WHEN I RECEIVED A ROLL CHK ON ACFT X, AN IFR DEP. HE WAS ASSIGNED HDG 270 DEGS CLBING TO 3000'. I CLRED COMMUTER X TO 8000' ON INITIAL CONTACT. I WAS TOLD BY THE TWR THAT FGT Y WOULD BE ON RWY HDG OFF RWY 34. I OBSERVED Y ON DEP GO 6-7 MI NW OF RIC HDG 340 DEGS AND CLB TO 3000'. FGT Y AT 7 MI NW SQUAWKED 1200 AND STARTED A LEFT TURN TO THE SE AND CLBED QUICKLY TO 4500'. I TOLD X TO MAINTAIN 4000' AND INFORMED HIM OF THE TFC. THESE TARGETS MERGED WITH X AT 4000' AND Y (NOW A 1200 SQUAWK) AT 4500.' AS THE TARGETS CLRED X WAS AT 4000' AND THE VFR FGT Y WAS AT 3700'. ACFT X RPTED THAT HE HAD TO PUSH THE NOSE OF HIS ACFT OVER AND RPTED A NMAC. FGT Y IN A LATER TELEPHONE CONVERSATION RPTED THAT HE HAD ACFT X IN SIGHT. FGT Y LEAVING HIS ASSIGNED FREQ AND MAKING A VFR TURN BACK TOWARD THE ARPT CONTRIBUTED TO THIS PROB DEVELOPING. I BELIEVE Y, IN FACT, HAD X IN SIGHT AND DSNDED TOO CLOSE TO HIM. POOR JUDGEMENT BY THIS PLT. STRICTER ATTN TO ARSA REQUIREMENTS BY FGT Y WOULD HAVE PREVENTED THIS OCCURRENCE. MONITORING OF 243.0 BY FGT Y WOULD HAVE PREVENTED THIS OCCURRENCE. THERE WAS SOME QUESTIONS ABOUT IFR DEP CLRNC FOR Y. HAD AN IFR BEEN FILED Y WOULD HAVE BEEN UNDER MORE POSITIVE CTL. THE PLT OF Y APPEARS TO HAVE BEEN IN MARGINAL WX AS ACFT X RPTED 1/2 MI VISIBILITY AND HEAVY SNOW.
