What was found
WHILE ON APPROACH, FLIGHT CREW RECEIVED AN AMBER FLAPS FAIL CAS MSG WHEN THE FLAP HANDLE WAS SELECTED TO THE 15 DEGREE POSITION. THE FLAPS STAYED AT THE 5 DEGREE POSITION & CREW REJECTED THE APPROACH SINCE THEY DID NOT MEET THE WET PERFORMANCE LANDING NUMBERS. FLIGHT CREW DIVERTED & FOLLOWING THE CHECKLIST, THEY WERE ABLE TO RESET THE FLAPS & CLEAR THE CAS MSG. ACFT LANDED UNEVENTFULLY WITH FULLY OPERATIONAL FLAPS. ONCE ON THE GND, FLIGHT CREW WORKING WITH MAINTENANCE CONTROL PERFORMED ANOTHER FLAP RESET & OPERATED SYS THROUGH SEVERAL COMPLETE CYCLES, WITH NO OTHER DEFECTS. DISCREPANCY WAS ENTERED AS AN INFO ONLY INTO THE LOG BOOK. NO REPEAT OF THE ISSUE SINCE.
