The position potentiometers on the 193549-1, and -2 Spring Control Wheel Assembly with Electric Trim assembly, and the 194864-1 Spring Loaded Control Wheel Assembly with Electric Trim have had reliability issues. This service bulletin modifies these assemblies from using Potentiometers to Hall Effect sensors.
The Seminole Engine control panel can become disconnected from the RTD Pogo Pins when down pressure is applied to the engine controls causing the engine control panel to loose communication with the RTD. The 194426-1 Pogo Pin Guide provides additional support around the Pogo connector to avoid the disconnection of the Pogo Pins for the Seminole Engine Control Panel.
The ribbon cable on the back right side of the 193241-1 G1000 overlay can become disconnected from the panel causing the G1000 MFD to be inoperative. Installing Mylar tape (FPN 162740-1) on the ribbon prevents the ribbon cable from becoming disconnected.
