4. Procedure
Subtask 52-36-00-210-050-A
A. Visual Inspection
   (1) Examine the hydraulic connections of the subsequent components and make sure that there are no leaks:
  • at the hand pump 3009GM
  • at the electro-manual selector valve 2500MJ
  • at the manual selector valves 2501MJ and 2504MJ
  • at the door actuators 2502MJ, 2503MJ, 2505MJ, 2506MJ
  • at the pipes.
   (2) Make sure that all components, pipes, clamps and brackets:
   (3) Make sure that in the area of the bulkhead(s) in the fuselage:
   (4) Make sure that the actuator fittings show no corrosion, scratches, marks and dents. For repair and minor corrosion (Ref. AMM TASK 51-73-11-300-001), (Ref. AMM TASK 51-74-11-300-001).
   (5) If there is corrosion to the outer surface of the door-actuator cylinder body:
     (a) Remove the door actuator (Ref. AMM TASK 52-36-18-000-001).
     (b) Send the door actuator to the workshop for repair.
     (c) Install the door actuator (Ref. AMM TASK 52-36-18-400-001).
   (6) Make sure that on the piston rod of the door actuator there are no longitudinal and/or transverse grooves.
     (a) Replace the door actuator if you find grooves or cracks on the piston rod (Ref. AMM TASK 52-36-18-000-001)/ (Ref. AMM TASK 52-36-18-400-001).
