## Discrepancy

DURING TAKEOFF, UPON GEAR RETRACTION, A LOUD NOISE FROM THE NOSE GEAR WAS NOTICED ACCOMPANIED BY A MOMENTARY (DISAGREE) WARNING AND TRIPLE CHIME.  THE NOISE CONTINUED FOLLOWED BY THE NOSE GEAR RETRACTING WITH ALL INDICATIONS SHOWING NORMAL.  AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO DEPARTURE, LANDING SAFELY.  MAINTENANCE REMOVED AND REPLACED THE NOSE LANDING GEAR PRIORITY VALVE.  OPERATIONAL AND LEAK CHECKS GOOD.  AIRCRAFT OK FOR SERVICE. (K)
