A CPR FLC IN A BE30 FLEW THROUGH A TURN POINT AND GOT OFF COURSE.

Narrative

THIS INCIDENT INVOLVED AN IFR TWR TO TWR FLT FROM VNY TO LGB USING THE PUBLISHED ROUTING. WHEN REVIEWING THE LOS ANGELES IFR AREA CHART PRIOR TO FLT; FOR SOME REASON WHICH I CANNOT EXPLAIN; I FAILED TO NOTICE THE INTXN OF V186 AND V394 (ADAMM) AND THOUGHT THE ROUTING REQUIRED CONTINUING TO PDZ VOR THEN WBOUND TO SLI VOR. THIS IS EXACTLY WHAT I DID WHILE FLYING THE RTE. TO PREVENT ATC FROM BRINGING THIS TO MY ATTN; AT SOME POINT; VERY NEAR ADAMM INTXN; COMS FAILURE (MY RECEIVER I ASSUME) OCCURRED. I REALIZED THIS NEAR PDZ VOR AND RE-ESTABLISHED COMS ON ANOTHER FREQ. AT THIS POINT I ALSO REALIZED MY ERROR IN ROUTING. MORE DILIGENCE IN PREFLT AND INFLT PLANNING IS THE MOST SIGNIFICANT FACTOR IN PREVENTING A RECURRENCE OF THIS TYPE OF INCIDENT. I FIND IT SOMEWHAT MORE STRESSFUL FLYING ROUTES WHICH ARE PRESCRIBED THAN THOSE WHICH I PLANNED MYSELF. UNFAMILIARITY WITH THE PARTICULAR RTE ALSO AFFECTED THE PROCESS. I AM VERY FAMILIAR WITH V186 AND THE ELMOO DEP CONTINUING ON TO PDZ VOR AND THIS ALSO MAY HAVE CONTRIBUTED TO MY FLAWED THOUGHT PROCESS.
