Narrative:

During climb out shortly after takeoff our left engine rolled back to idle. After retrimming the aircraft and adjusting to V2 climb speed; we ran the engine failure in-flight checklist. At this point; due to rising terrain; conditions of the day; and our close proximity to the airport we felt an expedited return to the airport was warranted. At this point we declared an emergency with departure control explaining our engine situation. They began vectoring us for appropriate MSA altitude and a return for landing. Once established at our assigned altitude we decided that an engine restart was appropriate. After running the in-flight engine start procedure; the left engine was operating normal. At this point we notified ATC that the left engine was back under normal operating conditions. We continued our landing to investigate the engine roll back with no further incident. Callback conversation with reporter revealed the following information: reporter stated that after landing; mechanics found no fault with the engine. The aircraft was released for flight and departed normally.

Title: A LR36'S LT ENG FLAMED OUT AFTER TKOF. AN EMER WAS DECLARED AND WHILE RETURNING TO LAND A SUCCESSFUL RELIGHT WAS ACCOMPLISHED FOLLOWED BY A NORMAL LNDG.

Narrative: DURING CLBOUT SHORTLY AFTER TKOF OUR L ENG ROLLED BACK TO IDLE. AFTER RETRIMMING THE ACFT AND ADJUSTING TO V2 CLB SPD; WE RAN THE ENG FAILURE INFLT CHKLIST. AT THIS POINT; DUE TO RISING TERRAIN; CONDITIONS OF THE DAY; AND OUR CLOSE PROX TO THE ARPT WE FELT AN EXPEDITED RETURN TO THE ARPT WAS WARRANTED. AT THIS POINT WE DECLARED AN EMER WITH DEP CTL EXPLAINING OUR ENG SITUATION. THEY BEGAN VECTORING US FOR APPROPRIATE MSA ALT AND A RETURN FOR LNDG. ONCE ESTABLISHED AT OUR ASSIGNED ALT WE DECIDED THAT AN ENG RESTART WAS APPROPRIATE. AFTER RUNNING THE INFLT ENG START PROC; THE L ENG WAS OPERATING NORMAL. AT THIS POINT WE NOTIFIED ATC THAT THE L ENG WAS BACK UNDER NORMAL OPERATING CONDITIONS. WE CONTINUED OUR LNDG TO INVESTIGATE THE ENG ROLL BACK WITH NO FURTHER INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: REPORTER STATED THAT AFTER LANDING; MECHANICS FOUND NO FAULT WITH THE ENG. THE ACFT WAS RELEASED FOR FLT AND DEPARTED NORMALLY.
