The system does not give any warning until something which is obvious happens. This can be the inability to hold and select RPM or airspeed sensitivity. Propeller governor maintenance is important as it prevents any malfunction of the system. Many components cause the failure of these systems. These include sticky prop-sticky blades, hydraulic locks, and leaks at the pilot valve.
The bearings that cause the rotations may wear out due to the shimming of the blades caused by the sticky props. This may cause the system, not function when given a command by the blade angles in the regulator when tightly fixed. This is not a major problem it can be resolved easily.
When the setting of a pitch is not done properly at the top of the refurbishment, there would be a problem in one way or another. Sometimes the set up for the turbocharged plane may be used for naturally aspirated plane with a single engine propeller. This may result in a problem since they have different propellers whereby the blades for a turbocharged plane are high pitched than the aspirated plane. This would make the system not function properly as the RPM may not go down for the aspirated planes and high for the turbocharged engine planes.
Those planes with twin engine in which the oil pressure decreases the plane angle usually are a subject of low pitch stop that can be improperly set. This results in improper static RPM since the blades cannot go low enough to allow maximum spinning engine. This malfunction normally occurs after maintenance of the prop-hub of any kind. However, there are similar symptoms sometimes that occur suddenly or gradually which is a clear indication of a system problem.
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.
When the hydraulic locks are not checked constantly, the may be a cause of the breakdown. These sides are usually forgotten during maintenance since they rarely malfunction. In the single-engine planes, the props should bring the RPM down. The double engine planes also use their props to bring the rpm down. However, when this system fails, there would not be any regulation. For this reason, it is important to consider the locks during maintenance.
Oil is usually transferred from the strengthener governor, and if there is any leakage from bellow, then prop will not be able to hit the high pitch on the single nor low pitch on the double. When there is too much leakage, the twin can go into commanded feather as a result of excessive clearance of the transport system.
Sometimes when there are no proper checkups on the plane, some parts tend to wear out without being noticed. The circled toe of the aircraft is one of them. When it touches the speeder-spring assembly, it causes the flyweight to wear out. The prop or plane cover starts clattering. This may cause excessive oil leakage in the pilot valve which may be mistaken to a problem from the engine transport system.
