Narrative:

On approximately 10 mi final for pvd runway 23, we were given a 200 degree heading to follow aircraft Y, B737, on a left downwind. Air carrier Y extended his downwind far enough as to turn directly towards us on his base turn. I did get distracted, asked approach for a turn to runway, considering I was between air carrier Y and the runway. Approach said he was already with tower. The B737 was coming directly towards us. I lost 200-300 ft altitude and made an evasive maneuver, climbed 500 ft and turned to a 090 degree heading. Air carrier Y passed off our right. I told approach I was turning left and they wanted me to turn right 310 degree heading. After B737 passed, I turned right 310 degree heading. I don't think anyone expected air carrier Y to extend so far, but when we found ourselves in the middle, it became very confusing as to the 'so called' plan the controller had. We should have never been turned into his potential flight path. As the PF, I let myself get distracted and my altitude loss was unacceptable. I should have broken off the approach earlier and pushed ATC to give us a reasonable plan.

Title: A BE02 WAS VECTORED AND SEQUENCED FOR A VISUAL APCH TO FOLLOW A B737 ON AN EXTENDED DOWNWIND LEG. WHEN THE B737 TURNED BASE LEG TO FINAL, THE BE02 WAS IN A POS BTWN THE B737 AND THE RWY. THE BE02 EXECUTED AN EVASIVE MANEUVER AND WAS RESEQUENCED BY APCH CTL.

Narrative: ON APPROX 10 MI FINAL FOR PVD RWY 23, WE WERE GIVEN A 200 DEG HDG TO FOLLOW ACFT Y, B737, ON A L DOWNWIND. ACR Y EXTENDED HIS DOWNWIND FAR ENOUGH AS TO TURN DIRECTLY TOWARDS US ON HIS BASE TURN. I DID GET DISTRACTED, ASKED APCH FOR A TURN TO RWY, CONSIDERING I WAS BTWN ACR Y AND THE RWY. APCH SAID HE WAS ALREADY WITH TWR. THE B737 WAS COMING DIRECTLY TOWARDS US. I LOST 200-300 FT ALT AND MADE AN EVASIVE MANEUVER, CLBED 500 FT AND TURNED TO A 090 DEG HDG. ACR Y PASSED OFF OUR R. I TOLD APCH I WAS TURNING L AND THEY WANTED ME TO TURN R 310 DEG HDG. AFTER B737 PASSED, I TURNED R 310 DEG HDG. I DON'T THINK ANYONE EXPECTED ACR Y TO EXTEND SO FAR, BUT WHEN WE FOUND OURSELVES IN THE MIDDLE, IT BECAME VERY CONFUSING AS TO THE 'SO CALLED' PLAN THE CTLR HAD. WE SHOULD HAVE NEVER BEEN TURNED INTO HIS POTENTIAL FLT PATH. AS THE PF, I LET MYSELF GET DISTRACTED AND MY ALT LOSS WAS UNACCEPTABLE. I SHOULD HAVE BROKEN OFF THE APCH EARLIER AND PUSHED ATC TO GIVE US A REASONABLE PLAN.
