Narrative:

Climbing through 4500 ft on the manteca 183 radial approximately 10 mi from sck airport, the controller called traffic at 11 O'clock less than a mi. I looked in the direction and saw an small aircraft at our altitude. We both took evasive action. He pulled up and we went under him. Told the controller how close we came. He apologized for the late warning. I called sck approach and told them a NASA report would be submitted. I was on an IFR flight plan. The small aircraft was VFR on a heading of 270 degrees approximate. I believe I heard the small aircraft pilot say that was close. I agree too close!

Title: COMMUTER ACFT HAS NMAC WITH SMA ON CLB OUT.

Narrative: CLBING THROUGH 4500 FT ON THE MANTECA 183 RADIAL APPROX 10 MI FROM SCK ARPT, THE CTLR CALLED TFC AT 11 O'CLOCK LESS THAN A MI. I LOOKED IN THE DIRECTION AND SAW AN SMA AT OUR ALT. WE BOTH TOOK EVASIVE ACTION. HE PULLED UP AND WE WENT UNDER HIM. TOLD THE CTLR HOW CLOSE WE CAME. HE APOLOGIZED FOR THE LATE WARNING. I CALLED SCK APCH AND TOLD THEM A NASA RPT WOULD BE SUBMITTED. I WAS ON AN IFR FLT PLAN. THE SMA WAS VFR ON A HDG OF 270 DEGS APPROXIMATE. I BELIEVE I HEARD THE SMA PLT SAY THAT WAS CLOSE. I AGREE TOO CLOSE!
