Narrative:

Passing 12000 ft in climb out, the right electronic engine control failed with momentary egt in amber. Checklist completed with no other abnormals noted. Flight continued to dfw. In the descent passing 11000 ft, the right engine failed to respond. Egt followed thrust lever movement and fuel flow was constant at 600 pounds. Engine was shut down per checklist. Emergency was declared and normal landing was made on runway 18R. Callback conversation with reporter revealed the following information: the reporter stated on climb out the right engine electronic engine control caused the engine to spool up momentarily into the amber band then the electronic engine control fail light came on. The reporter said the engine operated normally on the main fuel control until on approach to dfw where the engine began to spool down with no throttle response and the egt climbing. The reporter stated the engine was then shut down. The reporter said when maintenance checked the engine at the gate the preliminary report was main fuel control failure.

Title: A B757-200 ON CLBOUT HAD THE #2 ENG ELECTRONIC ENG CTL FAIL AND LATER ON APCH TO DFW AT 11000 FT THE ENG SPOOLED WITH HIGH EGT. ENG SHUTDOWN WITH SUSPECTED FUEL CTL FAILURE.

Narrative: PASSING 12000 FT IN CLBOUT, THE R ELECTRONIC ENG CTL FAILED WITH MOMENTARY EGT IN AMBER. CHKLIST COMPLETED WITH NO OTHER ABNORMALS NOTED. FLT CONTINUED TO DFW. IN THE DSCNT PASSING 11000 FT, THE R ENG FAILED TO RESPOND. EGT FOLLOWED THRUST LEVER MOVEMENT AND FUEL FLOW WAS CONSTANT AT 600 LBS. ENG WAS SHUT DOWN PER CHKLIST. EMER WAS DECLARED AND NORMAL LNDG WAS MADE ON RWY 18R. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED ON CLBOUT THE R ENG ELECTRONIC ENG CTL CAUSED THE ENG TO SPOOL UP MOMENTARILY INTO THE AMBER BAND THEN THE ELECTRONIC ENG CTL FAIL LIGHT CAME ON. THE RPTR SAID THE ENG OPERATED NORMALLY ON THE MAIN FUEL CTL UNTIL ON APCH TO DFW WHERE THE ENG BEGAN TO SPOOL DOWN WITH NO THROTTLE RESPONSE AND THE EGT CLBING. THE RPTR STATED THE ENG WAS THEN SHUT DOWN. THE RPTR SAID WHEN MAINT CHKED THE ENG AT THE GATE THE PRELIMINARY RPT WAS MAIN FUEL CTL FAILURE.
