## Discrepancy

(CAN) ON TAKEOFF, ONCE THE WEIGHT ON WHEELS SIGNAL WAS PRESENT, THE STICK SHAKER WARNING ACTUATED. PILOT RETURNED FOR LANDING.  ACFT SPEED WAS REPORTED AS CORRECT.  THE LT AOA TRANSMITTER WAS FOUND TO BE SENDING A SHAKER RANGE SIGNAL TO THE FCWU REGARDLESS OF THE PHYSICAL POSITION OF THE VANE. PART REPLACED, FUNCTION TESTS SATISFACTORY. (TC  20100225001)
