## Discrepancy

DURING CLIMB,  THE PILOT TRIED TO SELECT FLAP UP WITH NO RESPONSE.  THE FLAP INDICATION SHOWED THE RT FLAP AT 1 DEGREE AND THE LT FLAP AT 5 DEGREES. WITH NO RESPONSE TO THE FLAP HANDLE POSITION.  DECLARED AN EMERGENCY AND LANDED AT AN ALTERNATE AIRPORT. THE AIRCRAFT WAS ALWAYS UNDER CONTROL AND NO ROLL OR CONTROL ISSUES. REPLACED  THE RT FLAP POSITION TRANSMITTER AND THE FLAP POSITION INDICATOR CORRECTED THE DISCREPANCY.
