(8)
Do a check of the fluid level in the Blue reservoir. Add fluid as necessary (Ref. TASK 12-12-29-611-002) or (Ref. TASK 12-12-29-611-001).
(9)
Do the procedure steps (1) thru (8) again, two more times.

Depressurize the Blue hydraulic system (Ref. TASK 29-10-00-864-003).
(11)
Do the EIS stop procedure (Ref. TASK 31-60-00-860-002).
(12)
De-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002).
(13)
Do the subsequent steps to make sure that there is no air in the hydraulic system:
(a)
Do a check of the fluid level of the Blue reservoir.
(b)
If it is necessary to add fluid:
(c)
Make sure that the air pressure in the reservoir of the Blue hydraulic system is not less than 50 psi (3.4473 bar). If necessary, pressurize the reservoir (Ref. TASK 29-14-00-614-002).
(d)
Read the gage of the Blue reservoir and make a note of the fluid level.
(e)
Depressurize the reservoir of the Blue hydraulic system. (Ref. TASK 29-14-00-614-001).
(f)
After 5 minutes read the gage again and make a note of the level.
(g)
Compare both levels.
(h)
If the difference between both levels is more than 1 liter, do the bleeding procedure again until the result is satisfactory.
1_ Depressurize the reservoir (Ref. TASK 29-14-00-614-001)
2_ Keep the reservoir depressurization valve (2087GM) open and
fill the reservoir (Ref. TASK 12-12-29-611-002) or (Ref. TASK
12-12-29-611-001).
