TM 1-1520-238-T-7 Change 6 11–113 11–12. FLIGHT CONTROL SYSTEM – MAINTENANCE OPERATIONAL CHECK (cont) 11–12 Task Result r. Move pilot cyclic stick to the right approximately 3 to 4 inches. On pilot cyclic stick FORCE TRIM switch, remove pressure from FORCE TRIM REL position. If cyclic stick does not remain in right position, replace lateral (roll) magnetic brake (TM 1-1520-238-23). s. Hold pilot cyclic stick FORCE TRIM switch to FORCE TRIM REL. Move pilot cyclic stick slowly to center neutral position. If force trim does not disengage, go to paragraph 11–14. t. Move pilot cyclic stick (fig. 11–51) left approximately 3 or 4 inches. On pilot cyclic stick FORCE TRIM switch, remove pressure from FORCE TRIM REL position. If cyclic stick does not remain in left position, replace lateral (roll) magnetic brake (TM 1-1520-238-23). u. Hold pilot cyclic stick FORCE TRIM switch to FORCE TRIM REL. Move pilot cyclic stick slowly to center neutral position. If force trim does not disengage, go to paragraph 11–14. v. Move pilot right directional pedal (fig. 11–58) to approximately half way forward. On pilot cyclic stick FORCE TRIM switch, remove pressure from FORCE TRIM REL position. If right directional pedal does not remain in position, replace directional (yaw) magnetic brake (TM 1-1520-238-23). w. Hold pilot cyclic stick FORCE TRIM switch to FORCE TRIM REL. Move directional pedal slowly to neutral position. If force trim does not disengage, go to paragraph 11–14. x. Move pilot left directional pedal to approximately half way forward. On pilot cyclic stick FORCE TRIM switch, remove pressure from FORCE TRIM REL position. If left directional pedal does not remain in position, replace directional (yaw) magnetic brake (TM 1-1520-238-23). y. Hold pilot cyclic stick FORCE TRIM switch to FORCE TRIM REL. Move directional pedal slowly to neutral position. If force trim does not disengage, go to paragraph 11–14. 2. On pilot cyclic stick FORCE TRIM switch, remove pressure from FORCE TRIM REL position. 3. On pilot cyclic stick set FORCE TRIM switch to OFF. 4. Remove external power – electrical and hydraulic (primary) (TM 1-1520-238-23). END OF TASK
