TM 55-1520-240-T 7-1.4  FLIGHT CONTROL HYDRAULIC SYSTEM OPERATIONAL CHECK (Continued) 7-1.4 TASK RESULT 11. Check that FLT CONTR switch (14) is at BOTH. If not, set switch (14) to BOTH. 12 Set POWER XFR NO. 1 AND NO. 2 switches (1 and 2). NO. 1 HYD FLT CONTR (Without 74  ) HYD 1 (With  74 ) to  ON. and NO. 2 HYD FLT CONTR (Without 74  ) HYD 2 (With 74) capsules (12 and 13) shall go out.  If either capsule is still on, go to Task 7-12.15. 13 Check maintenance panel (15). FLT CONT NO. 1 and FLT CONT NO. 2 HYDRAULICS PRESS indicators (16 and 17) shall indicate 2500 to 3000 psi and pointers shall fluctuate more than 100 psi.  If either does not indicate more than 2500 to 3000 psi or pointer fluctuates more than 100 psi go to Task 8-7.3. If either pointer fluctuates from 1800 to 2200 psi, replace check valve on No. 1 or No. 2 power control module before replacing any module. Pointers on FLT CONT NO. 1 and FLT CONT NO. 2 HYDRAULICS TEMPERATURE indicators (18 and 19) shall move upscale as fluid temperature increases.  Tem- perature indication shall not exceed 95C.  If either pointer does not move, go to Task 8-8.3  If either pointer exceeds 95C, go to Task 7-1.15 or 7-1.16. FLT CONT NO. 1 PRESS and RTN FILTER CHANGE lights (20) shall be out.  If either light is on, go to Task 7-1.17. FLT CONT NO. 2 PRESS and RTN FILTER CHANGE lights (21) shall be out.  If either light is on, go to Task 7-1.18. 14. Slowly move pilot pitch and roll control and thrust Control and lever (22 and 23) travel shall be smooth and lever (22 and 23) through their travel range for 5 without binding or restriction.  All hoses to flight control minutes.   Check all flight control hydraulic system hydraulic system parts shall not be pinched, chaffed or components for leaks and ease of movement. stretched during control and lever movement.  Hydraulic fluid leakage shall not exceed limits noted in TM 55-1520-240-23.  If any binding or restriction is noted, locate cause and re-position or replace binding or restricted part.  Re-position hose if it is being pinched, chaffed, or stretched.  Tighten or replace leaking parts as required. TASK RESULT 15. Check two jam sensors on each actuator (24, 25, 26, If any sensor (28) is extended, go to Task 7-1.5. and 27). 16. Check jam sensor on  each actuator (29, 30, 31, and If any jam sensor button (33) is extended, go to Task 32). 7-1.19. 17. Repeat step 13, then go to step 18. 18. Set FLT CONTR switch (14) to NO. 1 ON. NO. 2 HYD FLT CONT (Without 74  ) capsule (13) shall come on.  HYD 2 (With  74  ) capsule (13) shall come on. If capsule does not come on, go to Task 7-1.20. 19. Set FLT CONTR switch (14) to NO. 2 ON. NO. 2 HYD FLT CONT (Without 74  ) capsule (13) shall go out.  HYD 2 (With  74 ) capsule (13) shall go out.  NO NO. 1 HYD FLT CONT (Without  74 ) capsule (12) shall come on.  HYD 1 (With  74  ) capsule (12) shall come on. If capsule (12) does not come on, go to Task 7-1.21. GO TO NEXT PAGE 7-16  Change 17
