A CPR CE560 CREW HAD TO SHUT DOWN ITS L ENG. INFLT ENG SHUTDOWN. EMER DECLARED. ENG RESTARTED. EMER CANCELED.

Narrative

UPON COMPLETION OF A DSCNT FROM FL370 TO FL200; THE PWR LEVERS WERE ADVANCED FROM IDLE TO CRUISE PWR. THE R ENG RESPONDED NORMALLY; HOWEVER; THE L ENG REMAINED AT IDLE PWR. AFTER TROUBLESHOOTING THE SIT AND CONSULTATION OF THE CHKLIST; A PRECAUTIONARY ENG SHUTDOWN WAS PERFORMED. AFTER FURTHER DISCUSSION; A SUCCESSFUL RESTART WAS PERFORMED; HOWEVER; THE L ENG REMAINED FROZEN AT IDLE PWR. THE DECISION TO NOTIFY ATC OF THE SIT WAS MADE AND AN EMER WAS DECLARED. A SECOND RESTART ATTEMPT WAS MADE WHICH RESULTED IN ESTABLISHING NORMAL PWR USE FROM THE L ENG. DURING THE EMER; TETEBORO ARPT WAS SELECTED AS THE ARPT OF LNDG. THE REASONS FOR THIS DECISION WERE THAT: 1) RWY LENGTH AT TEB WAS GREATER THAN THAT OF NEIGHBORING ARPTS SUCH AS MORRISTOWN; 2) THE FIRE AND RESCUE FACILITIES WERE EXCELLENT; 3) BOTH CREW MEMBERS WERE VERY FAMILIAR WITH THE OPS; IE; ATC; GEOGRAPHY; FACILITIES; AT TETEBORO. AFTER THE SUCCESSFUL RESTORATION OF PWR TO THE L ENG; ATC WAS NOTIFIED AND THE EMER WAS CANCELED. THE APCH AND LNDG WERE CONDUCTED UNDER NORMAL OPS.
