Narrative:

Received clearance on clearance delivery with void time 2 mins hence. Switched to advisory (CTAF), announced I was departing runway 17, performed a quick 360 degree clearing turn to search for traffic, crossed runway 13/31 and advised power for takeoff. Noticed back-taxiing bizjet, rejected takeoff, reversed direction, announced that I was departing runway 13 and departed. About the time I saw the bizjet, unicom informed me that the jet was back-taxiing and the jet turned on his landing/taxi lights. Flight was routine after that. My haste to meet void time was obvious contributor. Jet back-taxiing active runway instead of using txwys is another. Jet's silence throughout is another. Inability to see departure end of runway 17 from taxiway due to slope, vegetation is another. I'll reject short void periods in future to enhance situational awareness.

Title: SMA PLT AT CTAF BAZ ARPT ENCOUNTERS A BIZJET BACK-TAXIING AS HE STARTS HIS TKOF.

Narrative: RECEIVED CLRNC ON CLRNC DELIVERY WITH VOID TIME 2 MINS HENCE. SWITCHED TO ADVISORY (CTAF), ANNOUNCED I WAS DEPARTING RWY 17, PERFORMED A QUICK 360 DEG CLRING TURN TO SEARCH FOR TFC, CROSSED RWY 13/31 AND ADVISED PWR FOR TKOF. NOTICED BACK-TAXIING BIZJET, REJECTED TKOF, REVERSED DIRECTION, ANNOUNCED THAT I WAS DEPARTING RWY 13 AND DEPARTED. ABOUT THE TIME I SAW THE BIZJET, UNICOM INFORMED ME THAT THE JET WAS BACK-TAXIING AND THE JET TURNED ON HIS LNDG/TAXI LIGHTS. FLT WAS ROUTINE AFTER THAT. MY HASTE TO MEET VOID TIME WAS OBVIOUS CONTRIBUTOR. JET BACK-TAXIING ACTIVE RWY INSTEAD OF USING TXWYS IS ANOTHER. JET'S SILENCE THROUGHOUT IS ANOTHER. INABILITY TO SEE DEP END OF RWY 17 FROM TXWY DUE TO SLOPE, VEGETATION IS ANOTHER. I'LL REJECT SHORT VOID PERIODS IN FUTURE TO ENHANCE SITUATIONAL AWARENESS.
