A C560 CREW ON TKOF ROLL AT TEX; A NON TWR ARPT; SAW ANOTHER ACFT ON BASE LNDG OPPOSITE DIRECTION. AN EVASIVE CLB WAS INITIATED BY DEPARTING ACFT.

Narrative

WE WERE HOLDING SHORT OF RWY 27 AT TEX WAITING TO BE RELEASED. THERE WERE 3 ACFT INBOUND TO TEX. 2 VFR ACFT E OF THE FIELD (I WILL CALL THEM ACFT #1 AND ACFT #2) AND 1 ACFT W. THE ACFT W WAS A LEARJET ON AN IFR ARR TO RWY 9. THE OTHER 2 ACFT E OF THE FIELD WERE ALSO INBOUND FOR LNDG; HOWEVER; ONLY 1 WAS XMITTING ON UNICOM. WHILE ON THE GND; WE WERE ONLY AWARE OF THE LEAR WHICH WAS ON SHORT FINAL AND ACFT #1 THAT WE SAW SETTING UP FOR ABOUT A 2 MI FINAL FOR RWY 27. AS THE LEAR WAS ROLLING OUT ON LNDG; SOMEONE ON UNICOM XMITTED; 'ACFT E OF THE FIELD BE ADVISED THAT A LEAR IS ON THE RWY AND RWY 9 HAS BEEN THE RWY OF CHOICE FOR LNDG.' ACFT #2 (WHICH WE COULD NOT SEE) RESPONDED THAT THEY WERE NOT GOING TO LAND ON RWY 27 AND THEY WERE GOING TO ENTER A R DOWNWIND FOR RWY 9. AT THE SAME TIME; THIS WAS XMITTED; ACFT #1 BROKE OFF HIS/HER APCH FOR RWY 27 AND ENTERED A R DOWNWIND FOR RWY 9. ONCE THE LEAR CLRED THE RWY; WE WERE RELEASED FOR TKOF. MY FO XMITTED ON UNICOM;' THE ACFT THAT IS OVERHEAD THE FIELD; THIS IS CE560; WOULD YOU MIND IF WE DEPART TO MEET OUR VOID TIME?' ACFT #2 XMITTED BACK (WHICH WE THOUGHT WAS ACFT #1) 'YES; GO AHEAD AND DEPART; I WILL EXTEND MY DOWNWIND AND NOT TURN BASE UNTIL YOU ARE CLR.' AFTER WE STARTED TO PASS THROUGH 70 KTS; I SAW ACFT #1 START A TIGHT R BASE. AT THIS POINT WE HAD NO CHOICE BUT TO CONTINUE THE TKOF. WE MAINTAINED VISUAL CONTACT WITH ACFT #1 AS WE CLBED OUT. AT NO TIME DID ACFT #1 MAKE ANY EVASIVE ACTIONS TO AVOID US. WE WERE ABLE TO AVOID ACFT #1 BY CLBING OUT AT A RELATIVE HIGH RATE OF CLB. ACFT #1 OVERSHOT HIS FINAL AND APPEARED TO CONTINUE IN FOR A LNDG. IT THEN BECAME OBVIOUS TO US THAT THIS WAS NOT THE ACFT ACKNOWLEDGING OUR XMISSIONS. AS WE CONTINUED OUR CLBOUT; WE SAW ACFT #2 FOR THE FIRST TIME ON ABOUT A 2 MI WIDE R DOWNWIND FOR RWY 9. ACFT #1 (WHICH WE IDENTED TO BE A BONANZA) EITHER WAS NOT MONITORING UNICOM OR HAD NO RADIOS. THE LESSON WE LEARNED IS TO MAKE SURE THE ACFT WE ARE XMITTING TO IS THE ACFT WE HAVE IN VISUAL CONTACT WITH. IF IN DOUBT; WAIT FOR THE OTHER ACFT TO LAND. THIS ALSO COULD HAVE BEEN AVOIDED IF THE BONANZA WOULD HAVE MONITORED UNICOM OR XMITTED ON THE TEX UNICOM. THAT IS IF HE OR SHE DIDN'T HAVE A RADIO FAILURE.
