Narrative:

Small aircraft X complained of inadequate sep on a northbound departure off mkg. The other aircraft involved was small aircraft Y, executing an ILS runway 32 practice approach. Small aircraft X departed runway 6 on runway heading, initially bound for the north practice area. Small aircraft Y was instructed to execute his missed approach for the departing small aircraft X. Small aircraft Y was instructed to turn right heading 090 degrees. Small aircraft Y executed this turn southeast of the runway 6/24 centerline. Small aircraft X was instructed to turn left heading 360 degrees. While executing this turn, small aircraft X claims to have passed within 100' of small aircraft Y. At no time was a dangerous situation evident.

Title: POSSIBLE NMAC BETWEEN SMA X AND Y. SEE AND AVOID CONCEPT.

Narrative: SMA X COMPLAINED OF INADEQUATE SEP ON A NBND DEP OFF MKG. THE OTHER ACFT INVOLVED WAS SMA Y, EXECUTING AN ILS RWY 32 PRACTICE APCH. SMA X DEPARTED RWY 6 ON RWY HDG, INITIALLY BOUND FOR THE N PRACTICE AREA. SMA Y WAS INSTRUCTED TO EXECUTE HIS MISSED APCH FOR THE DEPARTING SMA X. SMA Y WAS INSTRUCTED TO TURN RIGHT HDG 090 DEGS. SMA Y EXECUTED THIS TURN SE OF THE RWY 6/24 CENTERLINE. SMA X WAS INSTRUCTED TO TURN LEFT HDG 360 DEGS. WHILE EXECUTING THIS TURN, SMA X CLAIMS TO HAVE PASSED WITHIN 100' OF SMA Y. AT NO TIME WAS A DANGEROUS SITUATION EVIDENT.
