Narrative:

The captain was flying the departure (payso 3). After crossing the NDB we were about to intercept the 030 degree right of srp. The captain began a 30 degree left bank turn from approximately 080 degrees to intercept the 030 degree right outbnd. Passing through about 060 degrees the F/east pointed to our right and I observed a light twin engine propeller (light brown, or tan) headed directly at us at our altitude. Before we could take any evasive action the twin propeller began a left climbing turn and passed over and behind our aircraft at approximately 400'. We had received no traffic callout from departure. I feel the major contributing factors were the following: allowing VFR traffic to fly uncontrolled in busy departure corridor of a major airport. Additionally we had previously been given our takeoff clearance based on our maintaining visual sep with a previously departed medium large transport. We had to keep him in sight while flying an instrument departure which somewhat detracted from our ability to observe other VFR traffic. Callback conversation with reporter revealed the following: confirmed that the near midair collision happened just inside the east boundary of the arsa. ATC advised reporters that they were not working the small transport and were unaware of his presence.

Title: LGT DEPARTING PHX HAS NMAC WITH SMT WITHIN THE ARSA.

Narrative: THE CAPT WAS FLYING THE DEP (PAYSO 3). AFTER XING THE NDB WE WERE ABOUT TO INTERCEPT THE 030 DEG R OF SRP. THE CAPT BEGAN A 30 DEG LEFT BANK TURN FROM APPROX 080 DEGS TO INTERCEPT THE 030 DEG R OUTBND. PASSING THROUGH ABOUT 060 DEGS THE F/E POINTED TO OUR RIGHT AND I OBSERVED A LIGHT TWIN ENG PROP (LIGHT BROWN, OR TAN) HEADED DIRECTLY AT US AT OUR ALT. BEFORE WE COULD TAKE ANY EVASIVE ACTION THE TWIN PROP BEGAN A LEFT CLBING TURN AND PASSED OVER AND BEHIND OUR ACFT AT APPROX 400'. WE HAD RECEIVED NO TFC CALLOUT FROM DEP. I FEEL THE MAJOR CONTRIBUTING FACTORS WERE THE FOLLOWING: ALLOWING VFR TFC TO FLY UNCONTROLLED IN BUSY DEP CORRIDOR OF A MAJOR ARPT. ADDITIONALLY WE HAD PREVIOUSLY BEEN GIVEN OUR TKOF CLRNC BASED ON OUR MAINTAINING VISUAL SEP WITH A PREVIOUSLY DEPARTED MLG. WE HAD TO KEEP HIM IN SIGHT WHILE FLYING AN INSTRUMENT DEP WHICH SOMEWHAT DETRACTED FROM OUR ABILITY TO OBSERVE OTHER VFR TFC. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: CONFIRMED THAT THE NMAC HAPPENED JUST INSIDE THE E BOUNDARY OF THE ARSA. ATC ADVISED REPORTERS THAT THEY WERE NOT WORKING THE SMT AND WERE UNAWARE OF HIS PRESENCE.
