    • If acceleration is continued or collective is decreased with stabilator trailing edge down, longitudinal control will be lost.
    • Slew stabilator to 0' above 40 kias, full down below 40 kias.
    • If stabilator is slewed to 0' and Auto Control Reset is pressed during acceleration, a pitch down nose attitude may occur.

    • Pressing Auto Control Reset after a failure results in auto mode for one second. 
    • If a signal to one actuator is present, the stabilator could move 4' - 5'.
    • Multiple attempts could result in an unsafe position.
  3. Stabilator Warning 3

    If the stabilator AUTO mode repeatedly disengages during flight, flight above 70 KIAS is prohibited with the stabilator in auto mode.

    • 1. Cyclic mounted stabilator slew up switch - Adjust if necessary to arrest or prevent nose down pitch rate.
    • 2. Auto Control switch - Press on once after establishing a comfortable airspeed.

    • If automatic control is not regained:
    • 3. Manually slew stabilator - Adjust to 0 for flights above 40KIAS, full down for flights below 40KIAS.
    • 4. LASA Prac

    • If manual control not possible:
    • 5. Stab pos indicator - Check and fly at or blow placarded kias limits.
    • 6. Practicable
