TM 1-1520-265-23 Figure 6-7. Pilot/Copilot Cyclic and Collective Stick Socket 6.8 COLLECTIVE BOOST AND YAW BOOST SERVO INPUT/OUTPUT PISTON SHAFTS AND CYLINDERS (MT). 6.8.1 Description (Figure 6-1. Index No. 8). The collective and yaw boost servos both reduce stick and flight control friction. 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 yaw boost servo. No cracks are allowed. 6.8.3 Primary Method. Magnetic Particle. 6.8.3.1 NDI Equipment and Materials. (Refer to Appendix B.) a. Magnetic Particle Inspection Probe/Yoke b. Magnetometer c. Black Light d. Fluorescent Magnetic Particles, refer to Table 1-8 e. Consumable Materials, refer to Table 1-8 f. Aircraft Marking Pencil, refer to Table 1-8 NOTE Hand-held magnetic coil may be used. Refer to paragraph 1.4.8.1.2 and Figure 1-6. 6-14
