PROBLEM
The fuel metering valve needs to be inspected and possibly reworked on certain G3516B, G3516C, G3516E, G3520B, G3520C, and G3520E engines. Some of the existing fuel metering valve main circuit boards contain a light conformal coating resulting in a valve failure and engine shutdown.
The light conformal coating is not sufficient to dampen vibration from ferrites on the main circuit board. When the ferrites vibrate, the electrical connection is fatigued until it breaks. When this occurs, the engine shuts down and the fuel control valve must be replaced.
