Narrative:
Phl final approach control was very busy with traffic. They gradually descended us to 4000' and vectored us to the southeast of the airport. A new controller came on the frequency and gave another aircraft instruction to turn right immediately, then gave us immediate left turn and descend to 3000'. I did not see the traffic due to our aircraft attitude. The copilot said that he was right there at 3 O'clock. The plane was a white twin engine aircraft. The copilot also stated that he did not consider this a near miss. I talked to the approach control supervisor after landing. He stated that training was being conducted at the time of the evasive action. He had seen the incident and removed both controllers off the scope and was reprimanding them at that time. He also stated that the other aircraft had us in sight. Suggestion: no trnees when that busy.

Title: CTLR TRAINEE ALLOWED LESS THAN STANDARD SEPARATION BETWEEN ACR-LGT AND ACR-LTT, BOTH ON VECTORS AT 4000'.
Narrative: PHL FINAL APCH CTL WAS VERY BUSY WITH TFC. THEY GRADUALLY DSNDED US TO 4000' AND VECTORED US TO THE SE OF THE ARPT. A NEW CTLR CAME ON THE FREQ AND GAVE ANOTHER ACFT INSTRUCTION TO TURN RIGHT IMMEDIATELY, THEN GAVE US IMMEDIATE LEFT TURN AND DSND TO 3000'. I DID NOT SEE THE TFC DUE TO OUR ACFT ATTITUDE. THE COPLT SAID THAT HE WAS RIGHT THERE AT 3 O'CLOCK. THE PLANE WAS A WHITE TWIN ENG ACFT. THE COPLT ALSO STATED THAT HE DID NOT CONSIDER THIS A NEAR MISS. I TALKED TO THE APCH CTL SUPVR AFTER LNDG. HE STATED THAT TRNING WAS BEING CONDUCTED AT THE TIME OF THE EVASIVE ACTION. HE HAD SEEN THE INCIDENT AND REMOVED BOTH CTLRS OFF THE SCOPE AND WAS REPRIMANDING THEM AT THAT TIME. HE ALSO STATED THAT THE OTHER ACFT HAD US IN SIGHT. SUGGESTION: NO TRNEES WHEN THAT BUSY.
