Narrative:

Departed lax on the gorman departure shafter transition. Over shafter VOR, climbing through FL315, ZLA asked me to stop the climb and turn left 20 degrees to avoid a possible conflict with large transport Y on parallel radar vector in the descent. His descent was stopped at FL328 and it was explained that a possible conflict existed. Upon inquiry I was informed that I was 3.5 mi off centerline. My position was directly over shafter turning outbnd to 328 degree right to intercept J65. Considering the arwy is a 4 mi either side of centerline, I feel that a conflict may have existed but was induced by the radar vector, in that I was in my protected airspace. Callback conversation with reporter revealed the following: reporter made a telephone call to ZLA from destination. He was informed that sep was not lost, but it was very close. Reporter's flight apparently overshot the VORTAC by about 4 mi and this was just far enough to bring his aircraft closer to the other large transport than the controller was expecting. The other large transport was being vectored on a parallel course to facilitate its descent and reporter's small deviation from course caused much concern.

Title: ACR LGT CLIMBING OVERSHOT TURN ONTO AIRWAY AND CAME NEAR ACR-LGT DESCENDING, OPPOSITE DIRECTION ON PARALLEL COURSE.

Narrative: DEPARTED LAX ON THE GORMAN DEP SHAFTER TRANSITION. OVER SHAFTER VOR, CLBING THROUGH FL315, ZLA ASKED ME TO STOP THE CLB AND TURN LEFT 20 DEGS TO AVOID A POSSIBLE CONFLICT WITH LGT Y ON PARALLEL RADAR VECTOR IN THE DSCNT. HIS DSCNT WAS STOPPED AT FL328 AND IT WAS EXPLAINED THAT A POSSIBLE CONFLICT EXISTED. UPON INQUIRY I WAS INFORMED THAT I WAS 3.5 MI OFF CENTERLINE. MY POS WAS DIRECTLY OVER SHAFTER TURNING OUTBND TO 328 DEG R TO INTERCEPT J65. CONSIDERING THE ARWY IS A 4 MI EITHER SIDE OF CENTERLINE, I FEEL THAT A CONFLICT MAY HAVE EXISTED BUT WAS INDUCED BY THE RADAR VECTOR, IN THAT I WAS IN MY PROTECTED AIRSPACE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR MADE A TELEPHONE CALL TO ZLA FROM DEST. HE WAS INFORMED THAT SEP WAS NOT LOST, BUT IT WAS VERY CLOSE. RPTR'S FLT APPARENTLY OVERSHOT THE VORTAC BY ABOUT 4 MI AND THIS WAS JUST FAR ENOUGH TO BRING HIS ACFT CLOSER TO THE OTHER LGT THAN THE CTLR WAS EXPECTING. THE OTHER LGT WAS BEING VECTORED ON A PARALLEL COURSE TO FACILITATE ITS DSCNT AND RPTR'S SMALL DEVIATION FROM COURSE CAUSED MUCH CONCERN.
