## Discrepancy

FLT NR 640 PHX-ONT - EMERGENCY LANDING, AFTER LANDING GEAR WAS SELECTED DOWN, GEAR INDICATION INTERMITTENTLY SHOWED NOSE GEAR NOT DOWN AND LOCKED.  RECYCLED GEAR WITH NO CHANGE.  CREW DECLARED AN EMERGENCY.  GEAR UNSAFE INDICATION EXTINGUISHED, THE AIRCRAFT LANDED UNVENTFULLY AND TAXIED TO THE GATE NORMALLY.  MAINTENANCE REMOVED AND REPLACED THE NR 2 LANDING GEAR CONTROL INTERFACE UNIT IAW AMM 32-31-71.  OPERATIONAL CHECK WAS GOOD.
