The Adapter assembly is used with A28005-35, -42 or -50 test equipment, used to perform a pressure decay test (leak test) of the shroud for the APU fuel line and drain line tubing. To perform the test, (A28005-50 and -24) or (A28005-42 and -24) or (A28005-35, incl -24) is
connected to the APU drain mast. The shroud is pressurized with dry, regulated, 0 - 50 psig air. The air source is then removed and the shroud is
monitored for leaks over a period of time. |
