## Discrepancy

PER AIRCRAFT ANNUAL INSPECTION, CHECKED THERMOSTATIC VALVE CONDITION.  FOUND THE SERIAL NUMBER OF THIS VALVE IS NOT SUBJECT TO INITIAL INSPECTION, BUT FOUND THIS THERMOSTATIC VALVE TO HAVE A LOOSE CRIMP NUT.  ALL THERMOSTATIC VALVES NEED TO BE CHECKED OR A NEW DESIGN OF SAFETING CRIMP NUTS.
