Narrative:

Aircraft #1 on approach vector in pvd class C airspace. Aircraft #1 had established radio contact with approach controller. After initial contact, aircraft #1 repeatedly attempted to contact approach controller. All attempts were met with silence. Aircraft #1 flew last assigned heading to within 1/4 mi of pvd. At this point, aircraft #1 was still on approach frequency, never being handed over to pvd tower. Approach controller suddenly reappeared on frequency and vectored aircraft #1 across final course of runway 23. This vector put aircraft #1 in a dangerous situation with aircraft #2 on final for runway 23. I believe aircraft #2 initiated a go around because of these actions. The chain of events could have been prevented had the approach controller: 1) handed aircraft #1 over to tower in a timely manner, 2) replied to the repeated contact attempts by aircraft #1, and 3) turned aircraft #1 away from the final approach course, not through it.

Title: PLT OF C150 HAS CLOSE ENCOUNTER WITH B757 ON APCH TO PVD WHEN APCH CTL IS UNABLE TO COMMUNICATE IN A TIMELY FASHION AFTER HE CHKED INTO THEIR AIRSPACE.

Narrative: ACFT #1 ON APCH VECTOR IN PVD CLASS C AIRSPACE. ACFT #1 HAD ESTABLISHED RADIO CONTACT WITH APCH CTLR. AFTER INITIAL CONTACT, ACFT #1 REPEATEDLY ATTEMPTED TO CONTACT APCH CTLR. ALL ATTEMPTS WERE MET WITH SILENCE. ACFT #1 FLEW LAST ASSIGNED HEADING TO WITHIN 1/4 MI OF PVD. AT THIS POINT, ACFT #1 WAS STILL ON APCH FREQ, NEVER BEING HANDED OVER TO PVD TWR. APCH CTLR SUDDENLY REAPPEARED ON FREQ AND VECTORED ACFT #1 ACROSS FINAL COURSE OF RWY 23. THIS VECTOR PUT ACFT #1 IN A DANGEROUS SIT WITH ACFT #2 ON FINAL FOR RWY 23. I BELIEVE ACFT #2 INITIATED A GAR BECAUSE OF THESE ACTIONS. THE CHAIN OF EVENTS COULD HAVE BEEN PREVENTED HAD THE APCH CTLR: 1) HANDED ACFT #1 OVER TO TWR IN A TIMELY MANNER, 2) REPLIED TO THE REPEATED CONTACT ATTEMPTS BY ACFT #1, AND 3) TURNED ACFT #1 AWAY FROM THE FINAL APCH COURSE, NOT THROUGH IT.
