Narrative:

Small aircraft cleared for takeoff ahead of us. Directed to turn crosswind as soon as possible after departure. After 1-2 mins we were cleared for takeoff assigned runway heading to 3000'. Sky clear but haze and bright sunlight reduced visibility to 2-3 NM. Shortly after gear retraction but before flaps up, I saw the small aircraft at about 11:30 less than 1 mi (still flying runway heading). As I pointed him out to the first officer who was PF, an anxious tower controller asked us if we had previous departure in sight. I replied that we did, and we blew by him with about 100 K of overtake. All happened very quickly. Lively discussion ensued between tower and small aircraft as to what his departure instructions had been. We were handed off to ny departure for the usual crazy vectors up and out of ny RAPCON airspace. If isp tower had radar they should have waited to clear us for takeoff until previously departed was observed in the turn. If no radar, they should have verbally confirmed that he was on a course out of the departure path. Another case of light AC and turbojet mix making for a bad brew. My second near midair collision over long island in 30 days.

Original NASA ASRS Text

Title: MLG HAS NMAC WITH SMA AFTER TKOF.

Narrative: SMA CLRED FOR TKOF AHEAD OF US. DIRECTED TO TURN XWIND ASAP AFTER DEP. AFTER 1-2 MINS WE WERE CLRED FOR TKOF ASSIGNED RWY HDG TO 3000'. SKY CLR BUT HAZE AND BRIGHT SUNLIGHT REDUCED VISIBILITY TO 2-3 NM. SHORTLY AFTER GEAR RETRACTION BUT BEFORE FLAPS UP, I SAW THE SMA AT ABOUT 11:30 LESS THAN 1 MI (STILL FLYING RWY HDG). AS I POINTED HIM OUT TO THE F/O WHO WAS PF, AN ANXIOUS TWR CTLR ASKED US IF WE HAD PREVIOUS DEP IN SIGHT. I REPLIED THAT WE DID, AND WE BLEW BY HIM WITH ABOUT 100 K OF OVERTAKE. ALL HAPPENED VERY QUICKLY. LIVELY DISCUSSION ENSUED BTWN TWR AND SMA AS TO WHAT HIS DEP INSTRUCTIONS HAD BEEN. WE WERE HANDED OFF TO NY DEP FOR THE USUAL CRAZY VECTORS UP AND OUT OF NY RAPCON AIRSPACE. IF ISP TWR HAD RADAR THEY SHOULD HAVE WAITED TO CLR US FOR TKOF UNTIL PREVIOUSLY DEPARTED WAS OBSERVED IN THE TURN. IF NO RADAR, THEY SHOULD HAVE VERBALLY CONFIRMED THAT HE WAS ON A COURSE OUT OF THE DEP PATH. ANOTHER CASE OF LIGHT AC AND TURBOJET MIX MAKING FOR A BAD BREW. MY SECOND NMAC OVER LONG ISLAND IN 30 DAYS.
