B. Leak Test of BMPS Sense Line

WARNING: WHEN YOU USE COMPRESSED AIR:

USE THE CORRECT PROTECTION (FACE SHIELD OR GOGGLES)
DO NOT POINT THE AIRFLOW AT YOURSELF OR OTHER PERSONS.

LOOSE PARTICLES AND/OR HIGH PRESSURE AIR CAN CAUSE INJURY.

WARNING: WHEN YOU USE COMPRESSED AIR:

USE THE CORRECT PROTECTION (FACE SHIELD OR GOGGLES)
DO NOT POINT THE AIRFLOW AT YOURSELF OR OTHER PERSONS.

LOOSE PARTICLES AND/OR HIGH PRESSURE AIR CAN CAUSE INJURY.

(1) Do the Test(s):

ACTION	RESULT
1.On the MCDU control panel: Push the SENSOR STATUS key.	On the MCDU: The SENSOR STATUS page comes into view and shows the bleed pressure.
2.Pressurize the 98L36103002000 TEST SET - ENGINE BLEED: A.If the AIR SOURCE - REGULATED, FILTERED, DRY has a manometer: Do not install the primary regulator valve. Slowly pressurize the 98L36103002000 TEST SET - ENGINE BLEED to 100 psi (6.89 bar) with the AIR SOURCE - REGULATED, FILTERED, DRY shutoff valve and the manometer. B.If the AIR SOURCE - REGULATED, FILTERED, DRY has no manometer: Install the primary regulator valve. NOTE: The primary regulator valve will keep the pressure in limit in the 98L36103002000 TEST SET - ENGINE BLEED to 217 psi (14.96 bar).
3.On the 98L36103002000 TEST SET - ENGINE BLEED: Open the shutoff valve. Slowly pressurize the system from 10 psi (0.69 bar) to 90 psi (6.21 bar) with the regulator valve of the 98L36103002000 TEST SET - ENGINE BLEED.	On the 98L36103002000 TEST SET - ENGINE BLEED: The digital pressure gage shows the pressure. On the SD: The status page shows the supplied pressure which must agree with the value of the digital pressure gage plus or minus 2 psi (0.14 bar).
4.On the 98L36103002000 TEST SET - ENGINE BLEED: Depressurize the system with the regulator valve of the 98L36103002000 TEST SET - ENGINE BLEED.	On the 98L36103002000 TEST SET - ENGINE BLEED: The digital pressure gage shows 0 psi (0.00 bar).

Subtask 36-11-00-080-108-A
