What was found
DID THE NEW FULL FUNCTIONAL CHECK OF OUR SENSORS ON OUR CF343B AND IT TOOK SOME TIME TO GET THE ONE SENSOR TO PASS AND THE OTHER ENGINE SENSOR NEEDED TO BE REPLACED. ON THAT SENSOR YOU COULD HEAR THE MECHANICAL HALF OF THE SENSOR ACTUATING BUT THE CONTACTS IN THE SENSOR/SWITCH NEVER CLOSED. (K)
