PLT OF HOMEBUILT SMA TOOK OFF FROM EBOUND TXWY VICE RWY 17 AS CLRED BY YUM.

Narrative

I WAS CLRED TO TAXI TO RWY 17 (THE SAME RWY I JUST LANDED ON). AFTER COMPLETING THE ACFT CHKLIST AND RUN-UP; THE TWR CLRED US FOR TKOF ON RWY 17. UNFORTUNATELY I DID NOT COMPLETE MY FINAL CHK; WHICH SHOULD HAVE BEEN TO VERIFY RWY MARKERS AND HEADING; AND I PROCEEDED TO TAKE OFF FROM A TXWY. I REALIZED MY ERROR SHORTLY AFTER I ROTATED; ABOUT THE SAME TIME THE TWR ADVISED ME OF MY ERROR. FACTORS LEADING UP THIS INCURSION INCLUDE THE FOLLOWING: 1) I HAD NOT LANDED AT THIS ARPT IN SEVERAL YEARS. ALTHOUGH I WAS NOT FAMILIAR WITH THE ARPT; I DID REVIEW ARPT INFO SUCH AS RWY LAYOUT AND RADIO FREQS; PRIOR TO LNDG. 2) THE RUN-UP AREA FOR RWY 17 IS AT THE NW CORNER OF A LARGE CONCRETE/PAVED AREA WHERE RWYS 8 AND 17; AND 2 TXWYS ORIGINATE (RWY 21 ALSO ORIGINATES IN THIS AREA). RWY 17 PASSES THROUGH THE MIDDLE OF THIS PAVED AREA AND IS IDENTED WITH STANDARD SIGNS AND MARKINGS; BUT THERE ARE NO BRUSH OR UNIMPROVED SURFACES DIFFERENTIATING THE SIDES OF THE RWY THAT ARE OBVIOUSLY VISIBLE FROM THE RUN-UP AREA. 3) THE TXWY I TOOK OFF FROM IS DIRECTLY IN FRONT OF THE RUN-UP AREA; AND LOOKED A LOT BETTER (WIDE; LONG; WELL PAVED; EMPTY) THAN MOST OF THE RWYS I USE AT OTHER ARPTS. RWY 17 WAS A SHARP TURN TO THE R. 4) THE WX WAS VERY HOT (107 DEGS F) AND THIS WAS THE FINAL LEG OF A FAIRLY LONG TRIP. I DID NOT FEEL TIRED OR DEHYDRATED; BUT IN HINDSIGHT THIS MAY HAVE BEEN A CONTRIBUTING FACTOR. I HAVE NO EXCUSE FOR THIS ERROR EXCEPT THAT I WAS ANXIOUS TO GET ON MY WAY; AND I DID NOT FOLLOW MY OWN PROCS AND TRAINING. SINCE I HAD JUST LANDED ON RWY 17; I LULLED MYSELF INTO THINKING THAT I KNEW WHERE I WAS ON THE ARPT; AND I DID NOT DO A FINAL CHK FOR RWY MARKERS AND ORIENTATION. I STILL CANNOT BELIEVE THAT I COULD HAVE BEEN SO CARELESS AND AM TAKING EVERY PRECAUTION TO MAKE SURE THAT IT WILL NEVER HAPPEN AGAIN.
