## Discrepancy

PROBLEM: WHILE THE AIRCRAFT WAS DEPARTING AND ON CLIMB FROM KISP TO KGAI THE FLIGHT CREW REPORTED," STICK SHAKER ACTIVATION AFTER TAKEOFF". THE AIRCRAFT DIVERTED BACK TO KISP AND MADE AN EMERGENCY LANDING WITHOUT INCIDENT. THE AIRCRAFT WAS ISSUED A FERRY PERMIT AND FERRIED TO KPSM WHERE REPAIRS COULD BE MADE. MAINTENANCE IN KPSM FOUND THE LH AOA TRANSMITTER TO BE FAULTY, IT WAS REMOVED AND REPLACED IAW PILATUS AMM 12-B-22-20-02-00A-920A-A.
