Narrative:

I was working east high position and received handoff on DH8 climbing to FL50. I had no traffic so I flashed the aircraft on the next sector (gibbs) and they flashed it on to ZMA. Therefore controller working east low sector turned the aircraft (DH8) on course and climbed him to FL120. A few mins later, I received a handoff from the gibbs sector, an E120 level at 110 nebound toward the DH8 who was still slow climbing through the gibbs airspace. The previous controller was training and failed to see that the airplanes were heading toward each other and were not separated. The E120 was switched to my frequency level at FL110. I had to take evasive action and turn the E120 sse to miss the DH8.

Original NASA ASRS Text

Title: DH8 CLB THROUGH OCCUPIED ALT HAD LTSS FROM E120. SYS ERROR.

Narrative: I WAS WORKING E HIGH POS AND RECEIVED HDOF ON DH8 CLBING TO FL50. I HAD NO TFC SO I FLASHED THE ACFT ON THE NEXT SECTOR (GIBBS) AND THEY FLASHED IT ON TO ZMA. THEREFORE CTLR WORKING E LOW SECTOR TURNED THE ACFT (DH8) ON COURSE AND CLBED HIM TO FL120. A FEW MINS LATER, I RECEIVED A HDOF FROM THE GIBBS SECTOR, AN E120 LEVEL AT 110 NEBOUND TOWARD THE DH8 WHO WAS STILL SLOW CLBING THROUGH THE GIBBS AIRSPACE. THE PREVIOUS CTLR WAS TRAINING AND FAILED TO SEE THAT THE AIRPLANES WERE HDG TOWARD EACH OTHER AND WERE NOT SEPARATED. THE E120 WAS SWITCHED TO MY FREQ LEVEL AT FL110. I HAD TO TAKE EVASIVE ACTION AND TURN THE E120 SSE TO MISS THE DH8.
