INST DEP; PLT CHANGES FREQ; MAKES TURN WITHOUT CLRNC TO DO SO.

Narrative

RECEIVED IFR CLRNC INFORMING ME TO EXPECT RADAR VECTORS AFTER TKOF. TWR CLRED ME FOR TKOF; WITH NO HDG TO TURN. I TOOK OFF AND STILL TWR DIDN'T GIVE ME A HDG. I CHANGED FREQ TO DEP AND BEFORE TALKING TO THEM; MADE A L DOWNWIND DEP. THIS IS THE FIRST TIME AT THIS ARPT FOR ME AND EARLIER I WAS WITH A LCL INSTRUCTOR GETTING AN ACFT CHKOUT. AFTER TKOF WE MADE A L DOWNWIND DEP. THAT'S WHY I MADE THE DECISION TO TURN L. POINT MUGU DEP IMPLIED THAT I DIDN'T LISTEN TO MY CLRNC AND NOTED THAT I MADE A L DOWNWIND DEP. I EXPLAINED TO THEM THAT I WASN'T GIVEN A VECTOR AND EARLIER THE L TURN SEEMED TO BE AUTHORIZED (RWY 8 HAS A R TFC PATTERN). IT WAS VFR CONDITIONS. THE IFR DEP PROC SPECIFIES TO CLB TO 2500 FT VIA CMA R-061 THEN ALL ACFT CLBING L TURN DIRECT CMA VOR DME. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES FIRST INST FLT SINCE RATING AND WAS WITH VERY EXPERIENCED PLT. HAD A 'THROW AWAY' TYPE ARPT DIAGRAM WHICH DID NOT INDICATE R TFC PATTERN. ANALYST COUNSELED REF PROPER CHARTS AND REQUEST FREQ CHANGE VERSUS JUST LEAVING FREQ. ANALYST ASSESSMENT: RPTR'S VERY EXPERIENCED PLT WAS NOT MUCH HELP!
