Overview

Actuator faults are not an option in flight.

Main Rotor and Tail Rotor Actuators control pitch, roll, and collective movement in a helicopter’s flight-control system. A fault in any one of them compromises stability and maneuverability, which is why every unit needs to be proven under real load, speed, and pressure conditions before it goes anywhere near an airframe.
