The regulatory system of the engines may not be noticed. You can only realize once they have stopped functioning. The source of the problem is usually the RPM and insensitivity to the airspeed. For all systems to work properly, you need to have a good propeller governor maintenance system. Parts such as hydraulic locks and pilot valve are usually vulnerable and should regularly be maintained.
The sticky prop may cause the shimming of blades making the bearing to wear out. This usually makes the system unresponsive to commands from the blade angles in the governor when they are too tight. However, this is a minor problem and may be less harmful compared to others.
At the prop repair site, when the pitch-stop is not set properly, it would result in a problem. Instead of a turbocharged model, a prop may be set up for the naturally aspirated airplane with one single engine propeller. The proof a turbocharged engine may have higher blade pitch compared to a naturally aspirated plane of the same model. This indicates that the systems are unable to keep the RPM down and at ascertain density.
Sometimes there are planes with double engines which the oil pressure reduces the angle of the blade making them stop using low pitch. These pitches can be set incorrectly resulting in a problem. The static RPM would be incorrect as the edges would not allow the engine to spin to the maximum. This is common especially when there has been a maintenance of a prop hub.
Sometimes the seal of a piston gets stuck and trapped in between the cylinder wall and the piston stick. This causes the piston to be trapped inside the prop dome. The engine may also damage the seal by t by tearing it especially when the engine has metal debris contamination. When they revolve and thrown by the centrifuge force, they cause damages. Dissembling the props and giving them sometimes for the debris to be removed is usually the best way to do upkeep and diagnosis.
Hydraulic locks can also malfunction and maintenance must be done to bring them back to normal function. However, this part rarely goes wrong. In one engine plane, the prop usually brings the RPM down as it should, but when there is a malfunction, the RPM does not go down as it is supposed to. On twin-engine, the effects are the opposite there would not be any correct static RPM. Good troubleshooting should be done.
The high pitch hit by the prop is affected by the leakage from below the regulator. If there is a huge oil leakage, then there would not be any high pitch or low in double and single-engine planes respectively.
The flyweight assembly of a plane can wear out when the circled toe touches the speeder-spring assembly. This will cause the hunting of prop as a result of wearing out. When a pilot valve is leaking oil excessively, it may start acting like a damaged engine transfer system, and the system would narrow this to the engine.
