12. Full Hydraulic System Internal Leakage Check and Isolation of Components with_____________________________________________________________________________ High Leakage.____________
A. General
(1)
If the system leakage is more than the approved leakage rates, you must find and replace the components with too much leakage. The tests must be done with the airplane in a landing configuration.
(2)
The approved total system null leakage limit is 4.5 GPM for the left and right systems and 4.0 GPM for the center system. If the null leakage is more than the allowable limits, replace components until the leakage is less than the limits.
