## Discrepancy

CLIMBING OUT, AROUND 14,000'  WE GOT A NR 1 RUDDER HYD CAUTION LIGHT. FEW SECONDS LATER WE GOT RUDDER CONTROL CAUTION LIGHT RAN BOTH CHECKLIST IN EMERGENCY BOOK. NOTICED LT INBD ROLL SPOILER SHOWED FULL DEFLECTION ON CAPT PFCS (MFD).  HAD NO NOTICE OF ANY ROLL CONDITION.  LOOKED OUT AND NR 1 SPOILER DID NOT APPEAR DEFLECTED. TURNED OFF AUTO PILOT TO SEE IF ANY ROLL, THERE WAS NONE. LT INBD SPOILER INDICATION FLUCTUATED.  FLIGHT CONTINUED, LANDING UNEVENTFUL. R & R LEFT INBD SPOILER LVDT IAW AMM 27-61-31-000-801/-400-801.  ALL REQUIRED TESTS GOOD.  NO CAUTION MESSAGES. RETURNED TO SERVICE.
