## Discrepancy

ON APPROACH AT 500 LBS TORQUE, WHILE LEVELING ALTITUDE AND ADVANCING POWER THE R/H ENGINE ATTEMPTED FEATHER CAUSING CYCLES SIMILAR TO AUTOFEATHER TEST. MAINTENANCE REMOVED AND REPLACED THE RIGHT HAND AUTOFEATHER LOW PRESSURE SWITCH AND COMPLIED WITH FCD 1900-09-61-01 & FCD 1900-08-61-01. PERFORMED GROUND RUNS AND PERFORMED AUTOFEATHER TEST IAW MM 61-20-00. OPERATIONAL CHECK WAS GOOD.
