NOTE: The slat actuators are vented units filled with grease. It is normal for this grease to have some oil separation. The external surfaces of the actuators can be moist with this grease as they are not hermetically sealed units.But separated oil in the units that touches the grease will be changed back during operation. The oil separation will decrease during in-service operation untilthe lubricant is in a condition that is stable. This is normal and will not cause damage to the units.
