Narrative:
2 aircraft were involved. The first aircraft (X) was direct mxf looking for vectors to the visual approach and given 4000 ft. The second aircraft (Y) was departing runway 15 at mxf with a climb to 4000 ft. The controller working the north sector forgot about the landing aircraft and climbed the departing aircraft to the same altitude as the arriving aircraft. If the south controller had put the arriving aircraft on a heading for the approach instead of leaving the aircraft direct, then it is possible that this situation would have been avoided.
Original NASA ASRS Text
Title: MGM TRACON CTLR DOES NOT APPLY REQUIRED VERT SEPARATION BTWN AN ARRIVING AND A DEPARTING BE40 BEING SEQUENCED AT MXF AFB.
Narrative: 2 ACFT WERE INVOLVED. THE FIRST ACFT (X) WAS DIRECT MXF LOOKING FOR VECTORS TO THE VISUAL APCH AND GIVEN 4000 FT. THE SECOND ACFT (Y) WAS DEPARTING RWY 15 AT MXF WITH A CLB TO 4000 FT. THE CTLR WORKING THE N SECTOR FORGOT ABOUT THE LNDG ACFT AND CLBED THE DEPARTING ACFT TO THE SAME ALT AS THE ARRIVING ACFT. IF THE S CTLR HAD PUT THE ARRIVING ACFT ON A HDG FOR THE APCH INSTEAD OF LEAVING THE ACFT DIRECT, THEN IT IS POSSIBLE THAT THIS SIT WOULD HAVE BEEN AVOIDED.
