## Discrepancy

ON TAKEOFF, THE AP1 BLINKED OFF AND IMMEDIATELY CAME BACK ON. NO OTHER ISSUES WERE OBSERVED UNTIL 1.3 HOURS OF FLIGHT WHEN "ACTUATOR" LIGHT AND MASTER CAUTIONS ILLUMINATED. INITIALLY LOST BOTH AP1 AND AP2. ATTEMPTED TO RE-ENGAGE THE APS AND THEY WOULD NOT COME ON. THE ACTUATOR THEN BECAME INTERMITTENT EVERY 2 SECONDS OR SO. REMOVED AND REPLACED SEMA ACTUATOR IAW AMM 67-20-00, 4-14. TF MOC COMPLETED IAW MSM 05-60-00, 6-1. CHECKS OK.
