R  Subtask 35-23-00-010-071 
R  B. Get Access 
R  (1) Open the AFT cargo-compartment door 826 (Ref. TASK 52-30-00-860-001). 
R  (2) Put the access platform below the AFT cargo-compartment door 826. 
R  (3) Set the CARGO COMPT LIGHT switch 8LU to the ON position. 
R  (4) Remove the related lining panel to get access to the oxygen storage 
R  (Ref. TASK 25-55-12-000-003). 
R  4. Procedure_________ 
R  Subtask 35-23-00-210-061 
R  A. Visual Inspection of the Oxygen Cylinder Pressure 
R  (Ref. Fig. 402/TASK 35-23-00-991-008) 
R  (1) Calculate the average pressure in the oxygen cylinders. 
R  (a) Read and write down the pressure on the gage of each oxygen 
R  cylinder. 
R  (b) Add the pressures together and divide the total by the number of 
R  installed oxygen cylinders. 
R  (2) Compare the calculated average pressure in the oxygen cylinders (PA) 
R  with the pressure on the fill panel pressure indicator 980WR (PI). 
R  (3) If the pressures PA and PI are the same, measure the ambient air 
R  temperature (TM) in the area of the oxygen cylinders with a 
R  THERMOMETER 50 DEG C (122 DEG F). 
R  (4) Refer to the table 
R  (Ref. Fig. 403/TASK 35-23-00-991-009) 
R  and the Flight Crew Operating Manual (FCOM) to calculate the oxygen 
R  supply available.

R  5. Close-up________ 
R  Subtask 35-23-00-410-070 
R  A. Close Access 
R  (1) Make sure that the work area is clean and clear of tool(s) and other 
R  items. 
R  (2) Install the related lining panel to close access to the oxygen 
R  storage (Ref. TASK 25-55-12-400-003). 
R  (3) Set the CARGO COMPT LIGHT switch 8LU to the OFF position. 
R  (4) Remove the access platform(s). 
R  (5) Close the AFT cargo-compartment door 826 (Ref. TASK 52-30-00-860-
R  002). 
R  Subtask 35-23-00-862-065 
R  B. De-energize the aircraft electrical circuits 
R  (Ref. TASK 24-41-00-862-002).
