## Discrepancy

BUF - FLT 1157 - AFTER TAKEOFF FROM BUF, EN ROUTE TO CLT, CREW EXPERIENCED A FLAP ASYMMETRY PROBLEM DURING FLAP RETRACTION.  ONE FLAP WAS IN THE 5 DEGREE POSITION AND THE OTHER WAS IN THE 2 DEGREE POSITION.  CREW DECLARED AN EMERGENCY AND RETURNED TO FIELD AT BUF WITHOUT FURTHER INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE FLAP POSITION INDICATOR AND INSPECTED/CLEANED CANNON PLUG ON FLAP TRANSMITTER.  OPERATIONAL CHECK GOOD.  (M)
