(a)
On the overhead maintenance panel 50VU, make sure that the HYD/LEAK MEASUREMENT VALVES/B P/BSW is set to off (OFF light is on).
(b)
If the P/BSW is not set to off (OFF light not on);
-stop the supply of pressure to the aircraft,
-wait for the pressure in the system to decrease,
-set the P/BSW to off (OFF light comes on),
-increase the supply of pressure to the same pressure as before.
(c)
In the Blue system compartment, turn the REAR manual selector valve to the ON position.
(d)
Monitor the flow shown on the ground supply flowmeter. It must not be more than 5.0 l.min (1.3208 USgal.mn).
(e)
In the Blue system compartment, turn the REAR manual selector valve to the OFF position.
