TM 1-1520-265-23Figure 6-7. Pilot/Copilot Cyclic and Collective Stick Socket6.8 COLLECTIVE BOOST AND YAW BOOST SERVO INPUT/OUTPUT PISTON SHAFTS AND CYLINDERS (MT).6.8.1 Description(Figure6-1.IndexNo.8). The collective and yaw boost servos both reduce stick and flight controlfriction. The yaw boost servo also provides rate damping through a SAS actuator.6.8.2 Defects.This inspection is used to verify crack indications found visually on the collective boost servo and yawboost servo. No cracks are allowed.6.8.3 PrimaryMethod.Magnetic Particle.6.8.3.1 NDI Equipment and Materials.
