The new maintenance schedule affected about 85 of the 165 Q400 aircraft worldwide. Some operators found that spare parts for this unexpected actuator replacement program were not available, grounding their aircraft indefinitely. [17] Investigators detected corrosion inside actuators on 25 of 27 aircraft they checked.
The result is an engine that fails to maintain idle RPM and frequently stalls. A jammed actuator may be freed simply by cleaning it. However an actuator that has stopped working due to a fault in its servomotor will need replacement. Air leaks in either the stepper housing or pipes will cause elevated idle RPM.
By connecting linkages to the nut, the motion can be converted to usable linear displacement. Most current actuators are built for high speed, high force, or a compromise between the two. When considering an actuator for a particular application, the most important specifications are typically travel, speed, force, accuracy, and lifetime.
Roughly 1.2 million taxpayers faced incredibly long waits last year for their tax refund cash after getting hit by tax-related ID theft, report says.
Electro-hydraulic actuators (EHAs), replace hydraulic systems with self-contained actuators operated solely by electrical power. EHAs eliminate the need for separate hydraulic pumps and tubing, because they include their own pump, [1] simplifying system architectures and improving safety and reliability. This technology originally was developed ...

The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...
