Narrative:

The flight was in level cruise at FL390 approximately 150 NM ese of jamestown, ny, in contact with ZNY. When the left engine was observed to be spooling down the captain immediately took control of the aircraft and initiated a descent out of FL390. Within 20-30 seconds of the left engine ceasing to operate, the right engine was observed to spool down also. The captain turned on air ignitions and standby fuel pumps and called for the engine failure checklist. As the aircraft descended, attempts were made to contact ZNY and obtain a different frequency but with no success. By this time we were squawking 7700 on the transponder. We also tuned to 121.5 and announced in the blind to any facility our call sign, position, and the nature of our problem. After several attempts, elmira approach answered the flight. I requested a vector to the nearest airport and was told that elmira county was approximately seven mi behind us. During this conversation, our attempts at a restart succeeded on the right engine through FL190. Normal power appeared to be available once again as we started to regain the cabin pressure. The controller issued vectors to the ILS runway 23 at elmira and verified that the crew was declaring an emergency. Approach control called the distance to the airport and gave us the latest WX and surface winds once again. Final items were accomplished for the landing with a single engine checklist as we intercepted the G/south. The copilot called the airport in sight approximately a mi out. The landing followed shortly and the aircraft was then evacuated. The captain shut the aircraft down on the runway while the fire department crew assisted in getting the patient onboard out of and away from the aircraft. The patient was then taken to a local hospital by the fire department ambulance. Cause has since been determined as fuel pump shaft shearing on left engine. Right engine flameout occurred due to loss of airspeed when left engine quit. Airflow was disturbed in right engine.

Title: FAILURE OF BOTH ENGINES OF SMT JET AT FL390 FORCED DESCENT. ONE ENGINE RESTARTED. FLT CREW ELECTED TO LAND AT NEAREST, ELM.

Narrative: THE FLT WAS IN LEVEL CRUISE AT FL390 APPROX 150 NM ESE OF JAMESTOWN, NY, IN CONTACT WITH ZNY. WHEN THE L ENG WAS OBSERVED TO BE SPOOLING DOWN THE CAPT IMMEDIATELY TOOK CTL OF THE ACFT AND INITIATED A DSNT OUT OF FL390. WITHIN 20-30 SECONDS OF THE L ENG CEASING TO OPERATE, THE R ENG WAS OBSERVED TO SPOOL DOWN ALSO. THE CAPT TURNED ON AIR IGNITIONS AND STANDBY FUEL PUMPS AND CALLED FOR THE ENG FAILURE CHKLIST. AS THE ACFT DSNDED, ATTEMPTS WERE MADE TO CONTACT ZNY AND OBTAIN A DIFFERENT FREQ BUT WITH NO SUCCESS. BY THIS TIME WE WERE SQUAWKING 7700 ON THE TRANSPONDER. WE ALSO TUNED TO 121.5 AND ANNOUNCED IN THE BLIND TO ANY FAC OUR CALL SIGN, POS, AND THE NATURE OF OUR PROB. AFTER SEVERAL ATTEMPTS, ELMIRA APCH ANSWERED THE FLT. I REQUESTED A VECTOR TO THE NEAREST ARPT AND WAS TOLD THAT ELMIRA COUNTY WAS APPROX SEVEN MI BEHIND US. DURING THIS CONVERSATION, OUR ATTEMPTS AT A RESTART SUCCEEDED ON THE R ENG THROUGH FL190. NORMAL PWR APPEARED TO BE AVAILABLE ONCE AGAIN AS WE STARTED TO REGAIN THE CABIN PRESSURE. THE CTLR ISSUED VECTORS TO THE ILS RWY 23 AT ELMIRA AND VERIFIED THAT THE CREW WAS DECLARING AN EMER. APCH CTL CALLED THE DISTANCE TO THE ARPT AND GAVE US THE LATEST WX AND SURFACE WINDS ONCE AGAIN. FINAL ITEMS WERE ACCOMPLISHED FOR THE LNDG WITH A SINGLE ENG CHKLIST AS WE INTERCEPTED THE G/S. THE COPLT CALLED THE ARPT IN SIGHT APPROX A MI OUT. THE LNDG FOLLOWED SHORTLY AND THE ACFT WAS THEN EVACUATED. THE CAPT SHUT THE ACFT DOWN ON THE RWY WHILE THE FIRE DEPT CREW ASSISTED IN GETTING THE PATIENT ONBOARD OUT OF AND AWAY FROM THE ACFT. THE PATIENT WAS THEN TAKEN TO A LCL HOSPITAL BY THE FIRE DEPT AMBULANCE. CAUSE HAS SINCE BEEN DETERMINED AS FUEL PUMP SHAFT SHEARING ON L ENG. R ENG FLAMEOUT OCCURRED DUE TO LOSS OF AIRSPD WHEN L ENG QUIT. AIRFLOW WAS DISTURBED IN R ENG.
