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.
The double engine planes have their oil pressure reduce the angle of their blades causing them to stop using low pitch. However, when set incorrectly the tones may result in a problem that needs immediate troubleshooting. The edges would not permit the engines to rotate fully causing a static RPM which is inaccurate.
The piston stick can also be a source of the malfunction. Usually, when the seal gets stuck and pressed in between the cylinder wall and the stick, the piston sticks to the prop dome. The engine may also tear the seal especially when the engines have been contaminated with the metal debris. This debris is thrown by the centrifugal force resulting into s malfunction. The prop should be dissembled when contaminated by metals and left for some time to remove the debris.
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.
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.
When the circled toe comes into contact with the speeder-spring assembly, the flyweight plane may wear out. The prop of a plane will start hunting causing excessive leakage of oil from the pilot valve which may start acting like engine transfer system problem.
