## Discrepancy

PASSING THROUGH FLIGHT LEVEL 230, THE RIGHT ENGINE EXPERIENCED COMPRESSOR STALLS. THE CREW COULD NOT RESTORE NORMAL ENGINE OPERATION VIA THE QUICK REFERENCE HANDBOOK PROCEDURES.  THE AIRPLANE WAS REMOVED FROM SERVICE AND THE RIGHT ENGINE'S MAIN ENGINE CONTROL (MEC), HYDROMECHANICAL FAN INLET TEMPERATURE (T2) SENSOR, AND THE COMPRESSOR INLET TEMPERATURE (CIT) SENSOR WERE REPLACED. THE CAUSE OF THE COMPRESSOR STALLS WAS A FAULTY MEC, T2 SENSOR, AND/OR CIT SENSOR.
