Narrative:

Climbing out of swf through 5000 ft had near midair collision with hang glider. We had had a brief pressure problem that caused us to stop our climb at 4000 ft. ATC then turned us to 360 degrees to avoid a cessna at 10 O'clock position. We fixed the problem and began our climb to 9000 ft while I (captain) entered direct weard in the FMS. The first officer was flying and he saw the hang glider first and began evasive maneuver to right. I looked up to see him pass off the left side of aircraft. We notified ATC and she said she would report it. Flight continued to atl. Causes: 1) hang glider flying too high in a high density area. 2) ATC failure to notify us of hang gliders in area. Although I don't think she knew of specific activity, she did say hang gliders were common in that area (we were over a ridge). 3) being distraction by cessna traffic which we saw, and I (captain, PNF) had my head down entering data in FMS. 4) being at lower than normal altitude due to pack (pressure) problem. 5) absence of NOTAMS on hang gliding activity in area. (At least none that we knew of.) solution: as usual, a series of problems led to the near midair collision starting with our pressurization procedure. It would seem to me that if the hang gliders were restr to a lower altitude, especially in that area, this could have been avoided. I hope the glider pilot is alright.

Title: A DEP CL65 NARROWLY MISSES A HANG GLIDER AT 5000 FT 18 MI NW OF SWF, NY.

Narrative: CLBING OUT OF SWF THROUGH 5000 FT HAD NMAC WITH HANG GLIDER. WE HAD HAD A BRIEF PRESSURE PROB THAT CAUSED US TO STOP OUR CLB AT 4000 FT. ATC THEN TURNED US TO 360 DEGS TO AVOID A CESSNA AT 10 O'CLOCK POS. WE FIXED THE PROB AND BEGAN OUR CLB TO 9000 FT WHILE I (CAPT) ENTERED DIRECT WEARD IN THE FMS. THE FO WAS FLYING AND HE SAW THE HANG GLIDER FIRST AND BEGAN EVASIVE MANEUVER TO R. I LOOKED UP TO SEE HIM PASS OFF THE L SIDE OF ACFT. WE NOTIFIED ATC AND SHE SAID SHE WOULD RPT IT. FLT CONTINUED TO ATL. CAUSES: 1) HANG GLIDER FLYING TOO HIGH IN A HIGH DENSITY AREA. 2) ATC FAILURE TO NOTIFY US OF HANG GLIDERS IN AREA. ALTHOUGH I DON'T THINK SHE KNEW OF SPECIFIC ACTIVITY, SHE DID SAY HANG GLIDERS WERE COMMON IN THAT AREA (WE WERE OVER A RIDGE). 3) BEING DISTR BY CESSNA TFC WHICH WE SAW, AND I (CAPT, PNF) HAD MY HEAD DOWN ENTERING DATA IN FMS. 4) BEING AT LOWER THAN NORMAL ALT DUE TO PACK (PRESSURE) PROB. 5) ABSENCE OF NOTAMS ON HANG GLIDING ACTIVITY IN AREA. (AT LEAST NONE THAT WE KNEW OF.) SOLUTION: AS USUAL, A SERIES OF PROBS LED TO THE NMAC STARTING WITH OUR PRESSURIZATION PROC. IT WOULD SEEM TO ME THAT IF THE HANG GLIDERS WERE RESTR TO A LOWER ALT, ESPECIALLY IN THAT AREA, THIS COULD HAVE BEEN AVOIDED. I HOPE THE GLIDER PLT IS ALRIGHT.
