## Discrepancy

PDX- ON FLIGHT 2135 AUTO FEATHER TEST DOES NOT TEST PROPERLY.  WHEN THE AUTO FEATHER SWITCHES ARE PULLED UP, BOTH PROPELLERS DROP DOWN INTO THE PROHIBITED RANGE AND THE UP TRIM DOES NOT ACTIVATE AND NOTHING HAPPENS WITH THE AUTO FEATHER.  LUBRICATED AUTO FEATHER SWITCHES.  NO PARTS REPLACED.  OPERATIONAL CHECKS GOOD.  AIRCRAFT RETURNED TO SERVICE.
