Narrative:

Climbing to 5000' on departure from lax, coast approach gave a vector of 130 degrees maintain 5000'. After leveling off the first officer (PNF) went 'off one' to call in our times on the #2 transmitter. Coast approach called traffic '12 O'clock, less than a mi, 5000'' as I looked up an small aircraft was less than 500' in front us, same altitude, same direction.as I reached for the controls (the autoplt was engaged) we entered his wake turbulence. I immediately initiated evasive action and missed him by about 300'. The scanning outside the aircraft could have been better. An small aircraft cruising at an IFR altitude just outside a TCA is an accident waiting to happen.

Narrative: CLBING TO 5000' ON DEP FROM LAX, COAST APCH GAVE A VECTOR OF 130 DEGS MAINTAIN 5000'. AFTER LEVELING OFF THE F/O (PNF) WENT 'OFF ONE' TO CALL IN OUR TIMES ON THE #2 XMITTER. COAST APCH CALLED TFC '12 O'CLOCK, LESS THAN A MI, 5000'' AS I LOOKED UP AN SMA WAS LESS THAN 500' IN FRONT US, SAME ALT, SAME DIRECTION.AS I REACHED FOR THE CTLS (THE AUTOPLT WAS ENGAGED) WE ENTERED HIS WAKE TURB. I IMMEDIATELY INITIATED EVASIVE ACTION AND MISSED HIM BY ABOUT 300'. THE SCANNING OUTSIDE THE ACFT COULD HAVE BEEN BETTER. AN SMA CRUISING AT AN IFR ALT JUST OUTSIDE A TCA IS AN ACCIDENT WAITING TO HAPPEN.
