HYDRAULIC SYSTEMS A, B, AND STANDBY - INSPECTION/CHECK
______________________________________________________
1. General_______
A. This procedure has one task. This task does a check of the hydraulic fluid.
B. The operational environment of the airplane hydraulic system can affect the service life of the hydraulic fluid. You make a decision to take a sample of the hydraulic fluid for analysis if you find that it is necessary from your service experience. Make sure that the fluid analysis results agree with the fluid specification limits shown in Table
601. If the fluid properties are greater than the limits in Table 601, replace some quantity of fluid with new fluid until the fluid properties agree with the limits shown. You make a decision on the quantity of fluid to be replaced.
C. A polyethylene bottle or a glass bottle can be used to collect the hydraulic fluid.
TASK 29-15-00-206-001
2. Hydraulic Fluid Check_____________________
