A. Get Access
   (1) Remove/open the access panel to the escape-slide inflation reservoir (Ref. AMM TASK 25-62-49-000-001).
4. Procedure

A. Visual Inspection
F Inflation Reservoir Pressure-Gage ** ON A/C NOT FOR ALL
   (1) Make sure that the pressure gage (1) (referred to as gage) shows the correct pressure.
NOTE: There are two different types of gage (1) (MODEL A and MODEL B). MODEL A has a green cursor which is temperature sensitive. MODEL B has a needle with an internal mechanism, which is temperature sensitive. They can give temporary low pressure indications when there are sudden temperature changes (from a cold to a warm environment). The cursor/needle moves to changes in temperature faster than the gas can expand in the inflation reservoir.
     (a) The permitted indications for MODEL A are as follows:
  • The needle in AREA A (green cursor width) shows that the pressure indication is correct.
  • The needle in AREA B, which is half the range of AREA A, shows a permitted indication, because of sudden temperature changes.
     (b) The permitted indications for MODEL B are as follows:
  • The GREEN BAND shows a correct indication
  • AREA B, which has a range equal to AREA A, shows a permitted indication because of sudden temperature changes.
     (c) If the gage (1) shows an incorrect indication:
       1 Let the temperature conditions become stable, then examine the gage (1) again.
       2 If the gage needle continues to show an incorrect indication, replace the inflation reservoir (Ref. AMM TASK 25-62-49-000-001).
