Narrative:

While working the BE36 inbound for albany on a right downwind for runway 28, an experimental aircraft departed runway 28 at sch and climbed at an extremely high rate on converging course with my BE36. The experimental aircraft climbed to 3500 ft within alb class C airspace. I issued a TA to the BE36 with an advisory to climb immediately. The BE36 did not acknowledge, however, he did comply. Targets merged with approximately 100-200 ft vertical separation. Pilot advised he never saw the traffic. This situation with sch tower and alb approach airspace has been a recurring problem.

Title: AN EXPERIMENTAL ACFT DEPARTS AN ADJACENT ARPT, ENTERS CLASS C AIRSPACE WITHOUT COORD AND HAS AN NMAC WITH AN ARRIVING BE36.

Narrative: WHILE WORKING THE BE36 INBOUND FOR ALBANY ON A R DOWNWIND FOR RWY 28, AN EXPERIMENTAL ACFT DEPARTED RWY 28 AT SCH AND CLBED AT AN EXTREMELY HIGH RATE ON CONVERGING COURSE WITH MY BE36. THE EXPERIMENTAL ACFT CLBED TO 3500 FT WITHIN ALB CLASS C AIRSPACE. I ISSUED A TA TO THE BE36 WITH AN ADVISORY TO CLB IMMEDIATELY. THE BE36 DID NOT ACKNOWLEDGE, HOWEVER, HE DID COMPLY. TARGETS MERGED WITH APPROX 100-200 FT VERT SEPARATION. PLT ADVISED HE NEVER SAW THE TFC. THIS SIT WITH SCH TWR AND ALB APCH AIRSPACE HAS BEEN A RECURRING PROB.
