## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON 09/02/2020 TWO PILOT'S, A FLIGHT INSTRUCTOR AND STUDENT WERE PRACTICING SIMULATED ENGINE FAILURES IN THE LOCAL PRACTICE AREA.  AFTER COMPLETION OF ONE MANEUVER AND CLIMBED BACK TO ALTITUDE.  ONCE AT ALTITUDE THE INSTRUCTOR NOTICED THE ENGINES DID NOT CREATE ITS NORMAL AMOUNT OF POWER AND THEY COULD NOT KEEP ALTITUDE.  THE FLIGHT INSTRUCTOR TRIED DIFFERENT MIXTURE SETTINGS AND PULLED THE CARBURETOR HEAT WITHOUT ANY IMPROVEMENT OF THE SYSTEM.

THE FLIGHT INSTRUCTOR RADIOED THE LOCAL AIRPORT TOWER, RIVERSIDE TOWER, WHICH IS WHERE THEY DEPARTED FROM AND TOLD THEM THEY MAY NEED TO MAKE AN OFF AIRPORT EMERGENCY LANDING.

THE PILOTS LANDED THE PLANE SOUTH OF LAKE MATTHEWS IN A FIELD.

AN INSPECTOR FROM THE RIVERSIDE FLIGHT STANDARDS DISTRICT OFFICE (FSDO) LOOKED AT THE AIRCRAFT AND SPOKE WITH THE FLIGHT INSTRUCTOR AND THE MECHANIC WHO INSPECTED THE PLANE AFTER THE OFF AIRPORT LANDING.

THE MECHANIC STATED HE FOUND FOREIGN DEBRIS IN THE CARBURETOR AND CHANGED THE CARBURETOR OUR WITH AN OVERHAULED ONE.

HE REPORTED NO ISSUES AFTER THE NEW INSTALLATION.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
