Narrative:

We were operating a flight from cvg-lga. Performed lda approach for landing runway 22 in dark night VMC. We were cleared to land on runway 22 at lga while still more than 5 mi out. During approach, a new tower controller came on frequency and cleared us to land again. We acknowledged that transmission and continued. When we were less than 2 mi from the runway 22 threshold, the controller cleared a BE1900 to depart on runway 31. I remarked to the first officer that that wouldn't work, the spacing appeared inadequate. When we were about 200 ft above the touchdown zone, the controller instructed us to go around. We began the go around immediately, but the other aircraft was already airborne and on a converging path. We did not take evasive maneuvers, but passed very close behind and no more than 100 ft above the other aircraft. After we were clear of the conflict, the controller instructed us to level at 1000 ft (although we were already at 1100 ft and the missed approach altitude was 2700 ft). This caused a small, additional threat to the safety of the flight. My guess is that the new controller was not fully aware of the position of the aircraft being handled.

Title: CL65 DSNDING AT 200 FT FOR RWY 22 AT LGA WAS ISSUED GAR BECAUSE OF TFC DEPARTING RWY 31, RESULTING IN AN NMAC.

Narrative: WE WERE OPERATING A FLT FROM CVG-LGA. PERFORMED LDA APCH FOR LNDG RWY 22 IN DARK NIGHT VMC. WE WERE CLRED TO LAND ON RWY 22 AT LGA WHILE STILL MORE THAN 5 MI OUT. DURING APCH, A NEW TWR CTLR CAME ON FREQ AND CLRED US TO LAND AGAIN. WE ACKNOWLEDGED THAT XMISSION AND CONTINUED. WHEN WE WERE LESS THAN 2 MI FROM THE RWY 22 THRESHOLD, THE CTLR CLRED A BE1900 TO DEPART ON RWY 31. I REMARKED TO THE FO THAT THAT WOULDN'T WORK, THE SPACING APPEARED INADEQUATE. WHEN WE WERE ABOUT 200 FT ABOVE THE TOUCHDOWN ZONE, THE CTLR INSTRUCTED US TO GO AROUND. WE BEGAN THE GAR IMMEDIATELY, BUT THE OTHER ACFT WAS ALREADY AIRBORNE AND ON A CONVERGING PATH. WE DID NOT TAKE EVASIVE MANEUVERS, BUT PASSED VERY CLOSE BEHIND AND NO MORE THAN 100 FT ABOVE THE OTHER ACFT. AFTER WE WERE CLR OF THE CONFLICT, THE CTLR INSTRUCTED US TO LEVEL AT 1000 FT (ALTHOUGH WE WERE ALREADY AT 1100 FT AND THE MISSED APCH ALT WAS 2700 FT). THIS CAUSED A SMALL, ADDITIONAL THREAT TO THE SAFETY OF THE FLT. MY GUESS IS THAT THE NEW CTLR WAS NOT FULLY AWARE OF THE POS OF THE ACFT BEING HANDLED.
