## Discrepancy

IN CRUISE, MULTIPLE CAS  MESSAGES AND X INDICATIONS ON ENGINE, ETC.   NOSE GEAR INDICATION UNSAFE WHILE RETRACTED AND EXTENDED.  WE PERFORMED A LOW PASS AND TOWER CONFIRMED ALL GEAR APPEARED DOWN.  EMERGENCY EXTENSION WAS PULLED PER THE CHECKLIST.    SOME CAS MESSAGES WOULD CLEAR AND OTHERS WOULD APPEAR.  IT SEEMED VERY RANDOM.  REMOVED GEA  AND INSTALLED REPAIRED UNIT. REF AMM 31-41-03. OPS CHECKS GOOD.
