compression of the strut to expel the entrapped air. An example procedure for bleeding the shock strut follows. 

1. Construct and attach a bleed hose containing a fitting suitable for making an airtight connection at the shock strut service valve port. Ensure a long enough hose to reach the ground while the aircraft is on jacks. 

2. Ja ck the aircraft until the shock struts are fully extended. 

3. Release any air pressure in the shock strut. 

4. Remove the air service valve assembly. 

5. Fil l the strut to the level of the service port with approved hydraulic fluid. 

6. Attach the bleed hose to the service port and insert the free end of the hose into a container of clean hydraulic fluid. The hose end must remain below the surface of the fluid. 

7. Place an exerciser jack or other suitable jack under the shock strut jacking point. Compress and extend the strut fully by raising and lowering the jack. Continue this process until all air bubbles cease to form in the container of hydraulic fluid. Compress the strut slowly and allow it to extend by its own weight. 

8. Remove the exerciser jack. Lower the aircraft and remove all other jacks.
