NOTE : 1. For the elevator and the aileron servocontrols, two leaks
____ of more than the normal operation limit are not permitted on the same flight surface.
NOTE : 2. Make sure that the connection is tightened to the correct
____
torque value.
NOTE : 3. The total leaks from the components and the connections,
____ that are part of the alternate brake system, must not be more than 10 drops/min.
NOTE : 4. Obey the subsequent leakage limits for the Yaw Damper
____
Servo-Actuators:
-
If the leakage rate is less than 4 drops per minute, no further action is necessary
-
If the leakage rate is between 4 and 14 drops per minute, replace the yaw damper servo-actuator(s) before the next 600
