What was found
KMLI - FIRST OFF, HAD THE AILERON TRIMMED LEFT WING DOWN FROM PREVIOUS FLIGHT AS FAR AS THE GREEN WOULD ALLOW TO GET THE TAKEOFF CONFIG OK MSG. TOOK THE RUNWAY (27) FOR DEPARTURE. WINDS WERE 190/18 GUSTING TO 21KTS. DIRECT CROSSWIND. AS CREW SET TAKEOFF POWER, EVERYTHING WAS GOOD. AT ABOUT 60 KTS RECEIVED A CONFIG AILERON WARNING. CREW ABORTED THE TAKEOFF, ALSO RECEIVED A CONFIG SPOILER AURAL WARNING. AFTER EXECUTING THE REJECTED TAKEOFF QRH AND AFTER LANDING CHECK, CREW CALLED AND TALKED TO MAINTENANCE ABOUT IT. BOTH CONCLUDED WITH THE AILERON TRIMMED LIKE IT WAS, THE GUSTY CROSSWIND PROBABLY CAUSED THIS WARNING. TRIED AGAIN, WITHOUT INCIDENT.
