## Discrepancy

WHEN TURBULENCE ARE ENCOUNTERED WE LOSE BOTH FLIGHT DIRECTOR,  YAW DAMPER,  FTC,  AUTOPILOT, AUTOTHROTTLE, TRP,  ALTITUDE READOUT ON MCP.  ONCE IN SMOOTH AIR EVERYTHING CAN BE RESET BUT REPEATS AS SOON AS TURBULENCE ARE ENCOUNTERED.  MX REMOVED AND REPLACED DIGITAL FGC. PN4068300-904.  ALL CHECKS GOOD
