What was found
AS SOON AS TAKEOFF POWER WAS SET WE OBSERVED AN AMBER ANNUNCIATOR INDICATING THE FLAPS WERE GREATER THAN 35 DEGREES PROMPTING AN IMMEDIATE REJECTION OF THE TAKEOFF. AS SOON AS THE THROTTLE WAS RETARDED THE MESSAGE DISAPPEARED. WITH THE MESSAGE EXTINGUISHED I PERFORMED ANOTHER POWER RUN TO DETERMINE IF THE MESSAGE WAS PERSISTING OR IF IT WAS AN INDICATION ISSUE. WE ALSO VERIFIED THE FLAP POSITION INDICATOR, WHICH DID INDICATE THE FLAPS WERE IN THE GROUND POSITION. WE EXITED THE RUNWAY AND PROCEEDED TO A RUN UP AREA IN AN ATTEMPT TO DIAGNOSE THE PROBLEM AND VERIFY THE POSITION OF THE FLAPS. A QUICK WALK AROUND INDICATED THAT THE FLAPS WERE IN FACT IN THE GROUND POSITION. A COCKPIT INSPECTION FOUND THAT THE FLAP CONTROL CIRCUIT BREAKER HAD POPPED OUT.
