## Discrepancy

ON WEDNESDAY, NOVEMBER 8TH, SERIAL NUMBER 000797 N775PA WAS CONDUCTING A PACKAGE DELIVERY IN LOCKEFORD, CA.  AFTER A NOMINAL DELIVERY, THE DRONE TRAVELED BACK TO THE PADDC LANDING LOCATION AND ENTERED THE VTOL LANDING PHASE OF FLIGHT ABOVE THE LANDING MARKER. DURING THE VTOL LANDING, THE DRONE SELF-INITIATED A SHUTDOWN OF THE FRONT RIGHT (#3) MOTOR, WITH ASSOCIATED HEALTH ALERT FOR MEP OUT FAILURE. THE DRONE COMPLETED A NOMINAL LANDING ON THE MARKER PER DESIGN. THE PROPELLER, MOTOR AND ESC HAVE BEEN REMOVED AND SHIPPED TO SEATTLE FOR FURTHER INVESTIGATION.
