Narrative:
Soon after starting an autothrottle VNAV descent on a STAR into dtw from oma, a vibration was felt throughout the airplane. The left engine turbine gas temperature was climbing toward 700 degrees and the fuel flow/hp/lp were all at normal VNAV readings. The left throttle was taken off autothrottle and reduced to idle. The turbine gas temperature stayed high. The engine was shut down. A coordinated change of destination was done through ATC to make a single-engine (uneventful) landing at mke. The fault was found to be a bad engine air control actuator. ATC and mke approach/tower coordination was professional and flawless.

Narrative: SOON AFTER STARTING AN AUTOTHROTTLE VNAV DSCNT ON A STAR INTO DTW FROM OMA, A VIBRATION WAS FELT THROUGHOUT THE AIRPLANE. THE L ENG TURBINE GAS TEMP WAS CLBING TOWARD 700 DEGS AND THE FUEL FLOW/HP/LP WERE ALL AT NORMAL VNAV READINGS. THE L THROTTLE WAS TAKEN OFF AUTOTHROTTLE AND REDUCED TO IDLE. THE TURBINE GAS TEMP STAYED HIGH. THE ENG WAS SHUT DOWN. A COORDINATED CHANGE OF DEST WAS DONE THROUGH ATC TO MAKE A SINGLE-ENG (UNEVENTFUL) LNDG AT MKE.
