## Discrepancy

IMMEDIATELY AFTER TAKEOFF GOT A STICK SHAKER WITH CONTINUOUS IGNITION WITH STALL LIGHT FLASHING.  FOS SIDE AIRSPEED TAPE HAD RED BARBER POLE FROM BOTTOM HIGHER THAN NORMAL.  ALSO GOT AUDIO WARBLER.  NEVER GOT STICK PUSHER.  DURING FLIGHT HIGH AIRSPEED BARBER POLE OVERLAPPED LOW AIRSPEED BARBER POLE.  UNABLE TO ENGAGE AUTOPILOT DUE TO ACFT THINKING IT WAS STALLED.  CONDITIONS CONTINUED UNTIL LANDING. (FLIGHT 6238)  INTERROGATED MDC, FOUND B1 CODE 007859. AOA B1 IS BELIEVED TO HAVE CAUSED STICK SHAKER ISSUES, SINCE THEY ARE ALL CONNECTED IN THE STALL PROTECTION SYSTEM. FROM THERE TROUBLESHOT AOA VANES, FOUND THAT THE FO'S SIDE WAS STICKING & NOT MOVING FREELY. LOOKED INTO AOA VANES & FOUND THE FO'S SIDE HAD BEEN REPLACED WITH AN OLD SERVICEABLE AOA VANE, SUSPECTED BAD PART FROM STOCK. R & R FO'S SIDE AOA VANE IAW AMM 27-35-05. OP CHECK GOOD, NO ISSUES.
