What was found
(CAN) TAKE OFF CONFIGURATION WARNING SOUNDED DURING TAKE OFF ROLL ON MANY OCCATIONS. DURING THIS CRITICAL TAKEOFF PHASE THAT EACH TIME THE ALARM SOUNDED, THE CREW MOVED THE PLA FROM TAKEOFF TO IDLE POSITION. THE CREW THEN ACTIONED THE GROUND SPOILER AND IT IS AT THIS MOMENT THAT THE CREW MOST LIKELY ASSOCIATED THE SOUNDING OF THE ALARM TO THE DEPLOYMENT OF THE GROUND SPOILER, WHILE THE ROOT CAUSE WAS WITH THE K3CL RELAY.
