1. Servicing of Emergency/Parking Brake Accumulator<br />
A. General<br />
(1) This section gives the procedure to charge the emergency/parking brake<br />
accumulator with nitrogen.<br />
B. Job Set-Up<br />
(1) Do the procedure to make the aircraft safe for maintenance (GHSH TASK<br />
20-00-00-910-801-A/200).<br />
(2) Put wheel chocks at the landing gear wheels.<br />
(3) Open access door 191BL.<br />
(4) Energize the aircraft with an external DC power supply (GHSH TASK 24-<br />
41-00-860-801-A/200).<br />
(5) Release the pressure from the hydraulic system (GHSH TASK 29-10-00-<br />
910-801-A/200).<br />
C. Servicing of Emergency/Parking Brake System<br />
(1) Remove the cap from the charging valve.<br />
(2) Connect the hose of the nitrogen A-A-59503 cylinder with an outlet connection<br />
to the charging valve.<br />
(3) Open the cylinder valve and actuate the pressure regulating valve to<br />
adjust the pressure.<br />
(4) Open the charging valve.<br />
(5) Stop the nitrogen supply when the pressure shown on the synoptic page of<br />
the CAS is according to the chart.<br />
(6) Close the cylinder valve.<br />
(7) Close the charging valve.<br />
(8) Repeat the next two steps until the nitrogen pressure is stable at the value<br />
given in the chart.<br />
(9) Look at the synoptic page of the CAS to see if the nitrogen pressure<br />
stayed stable.<br />
NOTE: Wait 10 minutes for the nitrogen pressure to become stable.<br />
(10)If necessary, adjust the nitrogen pressure again until it stays stable. To do<br />
so, open the cylinder valve and actuate the pressure regulating valve to<br />
adjust the pressure. (Refer to the chart).<br />
(11)Use a torque wrench to tighten the charging valve nut from 5.6 to 6.8 N.m<br />
(50 to 60 lb.in).<br />
(12)Do an inspection of the charging valve for leakage.<br />
(13)Use a torque wrench to install and tighten the cap from 1.5 to 3.5 N.m<br />
(13.3 to 31.0 lb.in).<br />
