GENERAL INFORMATIONGasket style Cylinder HeadTemperature thermocouples canread 50°F to100°F (normally about 60°F)more than bayonet style CHT’s. Whenreplacing an existing CHT probe (thermocouple) the same cylinder should be used fromwhere the old probe was removed. Some engines do not have thermowells to install bayonetprobes so gasket types must be used. In cold climates, thermowells are sometimes usedfor heater installations. Spring loaded bayonet types are more accurate than simple screwin types because the probe touches the bottom of the thermowell and senses metal ratherthan air temperature. If installing a new single probe system the original system must be leftintact unless a FAA 337 form is completed to approve its removal. Ensure that the probeinstalled is the same type as theone removed by comparing color ofwires. Some competitor's probesuse red and white colored wires,which are the same as yellow andblack wires. Do not confuse thermocoupleswith thermistors. Thermocouples produce millivolts, while thermistors change resistance. Allwork to be done in accordance with FAA, Advisory Circular 43.13-1A." />
FAA-PMA/STC SA 522 SW: This product is FAA approved for installation on ALL piston engine aircraft. After installation of complete system, return aircraft to service via Form 337 referencing STC SA 522 SW (see below). This is not required for replacement parts. All piston powered aircraft, regardless of make, are covered by this STC.
