## Discrepancy

AUTOTHROTTLE UNCOMMANDED DISENGAGE ON APPROACH.  PREVIOUS CREW REPORTED SAME ANOMALY, BUT WASN'T SURE IF THEY HAD  ACCIDENTALLY DISENGAGED IT OR IF A/T DISENGAGED ON ITS OWN.  WE DID NOT REENGAGE A/T AFTER IT DISENGAGED MANUAL THRUST TILL LANDING. PERFORMED AUTO THROTTLE / THRUST CONTROL QUADRANT INTERFACE OPERATIONAL TEST IAW E175 AMM 22-31-00-710-801-A. OPS CHECK GOOD. NO DEFECTS NOTED, RETURNED TO SERVICE.
