## Discrepancy

WHILE EN-ROUTE AT FL400 WE RECEIVED THE WHITE CAS MSG AHARS 1 & 2 FAULT.  UNDER THE MSG PAGE ON THE GTC WAS INDICATING GPS NAVIGATION SIGNALS WERE LOST.  APPROX 10 MINUTES LATER WE RECEIVED THE YELLOW YD FAIL AP FAIL SWPS FAIL & WHITE VENTRAL  RUDDER FAIL.  THE ACFT ENTERED A DUTCH ROLL WHICH WAS MOSTLY CONTROLLABLE.  WE DESCENDED TO FL250 & REGAINED CONTROL OF THE ACFT OUT OF FL290 APPROX.  SOMEWHERE AROUND 25000 FEET THE CAS MSGS DISAPPEARED & STAYED OFF FOR THE REMAINDER OF THE FLIGHT.
