NTSB Narrative Summary Released at Completion of Accident
THE LOCAL CONTROLLER POSITIONED SIMMONS 4058 ON RWY 9L FIRST, AND THEN POSITIONED SIMMONS 4158 (THIS AIRPLANE) ON RWY 4L. HE THEN RETURNED TO SIMMONS 4058, STATED THE RWY NUMBER, & CLEARED IT FOR TAKEOFF. BEFORE SIMMONS 4058 HAD A CHANCE TO REPLY, SIMMONS 4158 (THIS AIRPLANE) ACKNOWLEDGED THE CLEARANCE. SIMMONS 4058 QUERIED THE CLEARANCE. REALIZING THE CONFUSION, AND SEEING SIMMONS 4158 (THIS AIRPLANE) MOVING, THE CONTROLLER CANCELED SIMMONS 4058 TAKEOFF CLEARANCE.
