Narrative:

IFR training flight to providence, ATC clearance in use, before takeoff, tower advised that approach reported traffic southeast of the airport at 2500 ft. I acknowledged, and searched for traffic on departure. I found none. My IFR student contacted approach after flying runway heading. (160 degrees) approach told us to identify. Just as we did, I saw the traffic pass right to left under us, it appeared to be descending as we were climbing. I can't really tell exactly how close it was, but possibly less than 100 ft. Approach advised us to be in radar contact and we received vectors but no advisory, although the aircraft passed behind us. I feel that the other aircraft may have been in class 'D' without talking to tower, but, it was closer than I like it to get. Perhaps approach should not have released us for clearance until this traffic cleared our departure track.

Original NASA ASRS Text

Title: NMAC BTWN A DEP SMA SEL IFR AND ANOTHER ACFT DSNDING WITHIN CLASS D AIRSPACE.

Narrative: IFR TRAINING FLT TO PROVIDENCE, ATC CLRNC IN USE, BEFORE TKOF, TWR ADVISED THAT APCH RPTED TFC SE OF THE ARPT AT 2500 FT. I ACKNOWLEDGED, AND SEARCHED FOR TFC ON DEP. I FOUND NONE. MY IFR STUDENT CONTACTED APCH AFTER FLYING RWY HDG. (160 DEGS) APCH TOLD US TO IDENT. JUST AS WE DID, I SAW THE TFC PASS R TO L UNDER US, IT APPEARED TO BE DSNDING AS WE WERE CLBING. I CAN'T REALLY TELL EXACTLY HOW CLOSE IT WAS, BUT POSSIBLY LESS THAN 100 FT. APCH ADVISED US TO BE IN RADAR CONTACT AND WE RECEIVED VECTORS BUT NO ADVISORY, ALTHOUGH THE ACFT PASSED BEHIND US. I FEEL THAT THE OTHER ACFT MAY HAVE BEEN IN CLASS 'D' WITHOUT TALKING TO TWR, BUT, IT WAS CLOSER THAN I LIKE IT TO GET. PERHAPS APCH SHOULD NOT HAVE RELEASED US FOR CLRNC UNTIL THIS TFC CLRED OUR DEP TRACK.
