Narrative:

I was flying a test flight in our cpr airplane for a new digital air data computer, altimeter, and airspeed system. The last portion of the test card called for 2 takeoffs and 2 lndgs to a full stop to evaluate the displays. I elected to use brunswick-glynco airport which is an uncontrolled airport. On the first landing, I elected to land on runway 7 with reported winds of 210 degrees at 3 KTS. The only other traffic was an aztec just starting engines. The copilot was flying and I handled the radios. After the full stop on runway 7, I cleared the runway at the end and held short to take off on runway 25. The aztec and I communicated while he departed on runway 7. We then departed on runway 25 for right closed traffic for runway 25. I announced our intentions and the takeoff and subsequent landing were uneventful. While rolling out, I announced on unicom that I intended to do a 180 degree turn and depart on runway 7. I never heard the bonanza communicate on unicom as to his intention to taxi or take off on runway 25 or his query as to whether I had cleared the runway. I spotted the bonanza on our takeoff roll. He veered right on the runway. I took over the plane and expedited the takeoff. We cleared the runway and avoided the bonanza with plenty to spare. The unicom frequency for bqk gets overrun with traffic from other uncontrolled airports. I very well could have missed the bonanza's call. I will clear the runway from now on and listen carefully to all other radio calls.

Title: A CPR JET ON TKOF FROM RWY 7 HAS A NEAR COLLISION WITH A BE33 ON TKOF ON RWY 25 AT A NON TWR ARPT UNICOM.

Narrative: I WAS FLYING A TEST FLT IN OUR CPR AIRPLANE FOR A NEW DIGITAL AIR DATA COMPUTER, ALTIMETER, AND AIRSPD SYS. THE LAST PORTION OF THE TEST CARD CALLED FOR 2 TKOFS AND 2 LNDGS TO A FULL STOP TO EVALUATE THE DISPLAYS. I ELECTED TO USE BRUNSWICK-GLYNCO ARPT WHICH IS AN UNCTLED ARPT. ON THE FIRST LNDG, I ELECTED TO LAND ON RWY 7 WITH RPTED WINDS OF 210 DEGS AT 3 KTS. THE ONLY OTHER TFC WAS AN AZTEC JUST STARTING ENGS. THE COPLT WAS FLYING AND I HANDLED THE RADIOS. AFTER THE FULL STOP ON RWY 7, I CLRED THE RWY AT THE END AND HELD SHORT TO TAKE OFF ON RWY 25. THE AZTEC AND I COMMUNICATED WHILE HE DEPARTED ON RWY 7. WE THEN DEPARTED ON RWY 25 FOR R CLOSED TFC FOR RWY 25. I ANNOUNCED OUR INTENTIONS AND THE TKOF AND SUBSEQUENT LNDG WERE UNEVENTFUL. WHILE ROLLING OUT, I ANNOUNCED ON UNICOM THAT I INTENDED TO DO A 180 DEG TURN AND DEPART ON RWY 7. I NEVER HEARD THE BONANZA COMMUNICATE ON UNICOM AS TO HIS INTENTION TO TAXI OR TAKE OFF ON RWY 25 OR HIS QUERY AS TO WHETHER I HAD CLRED THE RWY. I SPOTTED THE BONANZA ON OUR TKOF ROLL. HE VEERED R ON THE RWY. I TOOK OVER THE PLANE AND EXPEDITED THE TKOF. WE CLRED THE RWY AND AVOIDED THE BONANZA WITH PLENTY TO SPARE. THE UNICOM FREQ FOR BQK GETS OVERRUN WITH TFC FROM OTHER UNCTLED ARPTS. I VERY WELL COULD HAVE MISSED THE BONANZA'S CALL. I WILL CLR THE RWY FROM NOW ON AND LISTEN CAREFULLY TO ALL OTHER RADIO CALLS.
