NTSB Narrative Summary Released at Completion of Accident
GLA268 (BEECH E33, N7135N) WAS CLEARED FOR TAKEOFF ON RWY 27L FROM THE BRANCH INTERSECTION BY A FULL PERFORMANCE LEVEL (FPL) CONTROLLER. AA9168 (MD-80, N490AA), WHICH HAD BEEN CLEARED TO RWY 27L BY A DEVELOPMENTAL CONTROLLER UNDER THE SUPERVISION OF THE FPL CONTROLLER, TWICE ACKNOWLEDGED THE TAKEOFF CLEARANCE FOR GLA268. GLA268 WAS AGAIN GIVEN TAKEOFF CLEARANCE BY THE FPL CONTROLLER. AT ABOUT THE SAME TIME AA9168 INITIATED ITS TAKEOFF ROLL FROM THE END OF THE RWY. AA9168 SAW GLA268 AHEAD OF IT AND QUERIED THE DEVELOPMENTAL CONTROLLER. AT THIS POINT THE FPL CONTROLLER TOOK OVER AND INSTRUCTED AA9168 TO ABORT ITS TAKEOFF. THE PILOT OF GLA268 REPORTED HE WAS ABOUT 50 FT AGL WHEN HE HEARD AA9168 ABORTING THE TAKEOFF.

THE FAILURE OF THE CONTROLLER TO CLARIFY THE CONFUSING COMMUNICATIONS, TO CORRECT THE PILOT'S MISINTERPRETATION OF THE INSTRUCTIONS BEING GIVEN, AND THE FAILURE OF THE SUPERVISOR TO PROPERLY MONITOR THE SITUATION. FACTORS RELATED TO THE INCIDENT WERE THE PILOT'S MISINTERPRETATION OF THE CLEARANCE, THE CONTROLLERS EXPECTANCY AND AURAL PERCEPTION OF THE COMMUNICATIONS.
