Narrative:

Filed tower en route emt to vny. I was cleared to vny, fly runway heading, at 800', left climbing turn, intercept pdz 276 degree right eastbound, pdz, V186, direct vny. Climb and maintain 4000'. Expect 6000' 5 mins after departure, departure frequency 125.5. Receive squawk from tower. I readback clearance, ground said readback correct. I took off. At 800', I began left turn and climb. Tower said contact ontario approach at 2000'. At 2000' I contacted ontario approach. By this time I was directly over emt, westbound on a heading of 276 tracking 276 degree right , pdz outbnd. Controller asked for identify. I idented. Controller then said my departure course was incorrect, ordered an immediate 180 degree turn and expedited climb to 6000'. I complied. Controller then stated that I was supposed to be on the standard emt departure. I stated that I thought that's what I had executed. I now realized my mistake. I had flown the pdz 276 degree right 'outbnd' not 'eastbound' as instructed. I apologized to the controller for my mistake and swallowed my pride. I had just undergone a BFR 2 months before, checked out IFR in a complex single and recently had even done simulator work with an instuctor. After first receiving clearance, I thought it unusual that I would have to fly to pdz first, even though vny was opp direction. I thought to myself this can't be. Instead of double checking with ground after clearance, I stupidly flew the wrong way after thinking 'eastbound' and 'outbnd' were the same direction. I am extremely embarassed by this mistake. A clearance is very clear and direct. Even after working on a chart, I began to interpret the clearance differently, why? I don't know other than to say the clearance sounded stupid and despite going through it once in my head to verify it, I'm the one that looks stupid in the end. In the future if there's even the slightest doubt or confusion I will double check the clearance with ground; especially when flying from an airport for the first time.

Title: SMA PLT FLIES WRONG DIRECTION ON RADIAL ON IFR CLRNC. CTLR INTERVENES.

Narrative: FILED TWR ENRTE EMT TO VNY. I WAS CLRED TO VNY, FLY RWY HDG, AT 800', L CLBING TURN, INTERCEPT PDZ 276 DEG R EBND, PDZ, V186, DIRECT VNY. CLB AND MAINTAIN 4000'. EXPECT 6000' 5 MINS AFTER DEP, DEP FREQ 125.5. RECEIVE SQUAWK FROM TWR. I READBACK CLRNC, GND SAID READBACK CORRECT. I TOOK OFF. AT 800', I BEGAN L TURN AND CLB. TWR SAID CONTACT ONTARIO APCH AT 2000'. AT 2000' I CONTACTED ONTARIO APCH. BY THIS TIME I WAS DIRECTLY OVER EMT, WBND ON A HDG OF 276 TRACKING 276 DEG R , PDZ OUTBND. CTLR ASKED FOR IDENT. I IDENTED. CTLR THEN SAID MY DEP COURSE WAS INCORRECT, ORDERED AN IMMEDIATE 180 DEG TURN AND EXPEDITED CLB TO 6000'. I COMPLIED. CTLR THEN STATED THAT I WAS SUPPOSED TO BE ON THE STANDARD EMT DEP. I STATED THAT I THOUGHT THAT'S WHAT I HAD EXECUTED. I NOW REALIZED MY MISTAKE. I HAD FLOWN THE PDZ 276 DEG R 'OUTBND' NOT 'EBND' AS INSTRUCTED. I APOLOGIZED TO THE CTLR FOR MY MISTAKE AND SWALLOWED MY PRIDE. I HAD JUST UNDERGONE A BFR 2 MONTHS BEFORE, CHKED OUT IFR IN A COMPLEX SINGLE AND RECENTLY HAD EVEN DONE SIMULATOR WORK WITH AN INSTUCTOR. AFTER FIRST RECEIVING CLRNC, I THOUGHT IT UNUSUAL THAT I WOULD HAVE TO FLY TO PDZ FIRST, EVEN THOUGH VNY WAS OPP DIRECTION. I THOUGHT TO MYSELF THIS CAN'T BE. INSTEAD OF DOUBLE CHKING WITH GND AFTER CLRNC, I STUPIDLY FLEW THE WRONG WAY AFTER THINKING 'EBND' AND 'OUTBND' WERE THE SAME DIRECTION. I AM EXTREMELY EMBARASSED BY THIS MISTAKE. A CLRNC IS VERY CLR AND DIRECT. EVEN AFTER WORKING ON A CHART, I BEGAN TO INTERPRET THE CLRNC DIFFERENTLY, WHY? I DON'T KNOW OTHER THAN TO SAY THE CLRNC SOUNDED STUPID AND DESPITE GOING THROUGH IT ONCE IN MY HEAD TO VERIFY IT, I'M THE ONE THAT LOOKS STUPID IN THE END. IN THE FUTURE IF THERE'S EVEN THE SLIGHTEST DOUBT OR CONFUSION I WILL DOUBLE CHK THE CLRNC WITH GND; ESPECIALLY WHEN FLYING FROM AN ARPT FOR THE FIRST TIME.
