## Discrepancy

ON SHORT FINAL POWER WAS AT 42 PERCENT N1 AT WHICH TIME OUR DESCENT RATE INCREASED DUE TO A SINKER.  AUTOTHROTTLES DID NOT ADEQUATELY RESPOND SO CAPTAIN INTERVENED AND INCREASED THRUST MANUALLY.  WOULD HAVE BEEN EXTREMELY HARD LANDING WITHOUT PILOT INTERVENTION.  WIND WAS 010-7KTS.  ACFT GROUNDED.  FLIGHT FAULT REVIEW SHOWS NO FAULTS LAST LEG.  ACCOMPLISHED LAND VERIFY, REF AMM 22-11-00.  OPS NORMAL.  HGS OPS NORMAL, REF AMM 34-36-00.  ACFT REMAINS CAT 3 AUTOLAND AND HGS,  SCREW REFLECTS SAME.
