Narrative:

The emergency occurred during a reposition flight on jan/xa/00 from springfield, mo, to st. Louis, mo. Approximately 20 mi west of st. Louis, the left engine quit. The torque and RPM gauges both indicated 0. We started to execute the single engine failure memory items. While identifying the feather lever, the right engine failed. At this time, approach called to give us a vector. We told them we had an emergency and would get back to them. We started to execute the double engine failure memory items. After approximately 30 seconds, the left engine relit. I then added power to the left engine and used it as normal. We then executed the memory items on the right engine and ran the engine shutdown checklist. We then called approach and let them know that we had one engine back and we still had an emergency. They vectored us for a straight in ILS to stl. I made a decision not to restart the engine due to the lack of time remaining in the flight. We were now approximately 10 mi west of st. Louis. The WX was 400 overcast and 2 1/2 SM visibility. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a BAE3200 with two garrett TPE331-12UAR engines. The reporter said the left engine had been worked for oil pressure and RPM fluctuations but the fluctuations of about 1 percent were still present. The reporter stated the cause of the right engine loss of power and shutdown was a failed engine driven fuel pump. The reporter said the cause of the left engine momentary loss of power is unknown. Callback conversation with reporter acn 459769 revealed the following information: the reporter stated the #1 engine was previously worked for an RPM and oil pressure log report of fluctuating. The reporter said the fluctuation was not corrected as it was present during the flight. The reporter stated no cause has been reported by maintenance for the 30 second loss of power on #1 engine. The reporter said #2 engine experienced a failed engine driven fuel pump.

Title: A BAE3200 IN DSCNT AT 8000 FT DECLARED AN EMER DUE TO A DOUBLE ENG FAILURE CAUSED BY A R ENG FAILED FUEL PUMP. L ENG AUTO RESTART OK. CAUSE OF L ENG 30 SECOND PWR LOSS UNKNOWN.

Narrative: THE EMER OCCURRED DURING A REPOSITION FLT ON JAN/XA/00 FROM SPRINGFIELD, MO, TO ST. LOUIS, MO. APPROX 20 MI W OF ST. LOUIS, THE L ENG QUIT. THE TORQUE AND RPM GAUGES BOTH INDICATED 0. WE STARTED TO EXECUTE THE SINGLE ENG FAILURE MEMORY ITEMS. WHILE IDENTIFYING THE FEATHER LEVER, THE R ENG FAILED. AT THIS TIME, APCH CALLED TO GIVE US A VECTOR. WE TOLD THEM WE HAD AN EMER AND WOULD GET BACK TO THEM. WE STARTED TO EXECUTE THE DOUBLE ENG FAILURE MEMORY ITEMS. AFTER APPROX 30 SECONDS, THE L ENG RELIT. I THEN ADDED PWR TO THE L ENG AND USED IT AS NORMAL. WE THEN EXECUTED THE MEMORY ITEMS ON THE R ENG AND RAN THE ENG SHUTDOWN CHECKLIST. WE THEN CALLED APCH AND LET THEM KNOW THAT WE HAD ONE ENG BACK AND WE STILL HAD AN EMER. THEY VECTORED US FOR A STRAIGHT IN ILS TO STL. I MADE A DECISION NOT TO RESTART THE ENG DUE TO THE LACK OF TIME REMAINING IN THE FLT. WE WERE NOW APPROX 10 MI W OF ST. LOUIS. THE WX WAS 400 OVERCAST AND 2 1/2 SM VISIBILITY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A BAE3200 WITH TWO GARRETT TPE331-12UAR ENGS. THE RPTR SAID THE L ENG HAD BEEN WORKED FOR OIL PRESSURE AND RPM FLUCTUATIONS BUT THE FLUCTUATIONS OF ABOUT 1 PERCENT WERE STILL PRESENT. THE RPTR STATED THE CAUSE OF THE R ENG LOSS OF PWR AND SHUTDOWN WAS A FAILED ENG DRIVEN FUEL PUMP. THE RPTR SAID THE CAUSE OF THE L ENG MOMENTARY LOSS OF PWR IS UNKNOWN. CALLBACK CONVERSATION WITH RPTR ACN 459769 REVEALED THE FOLLOWING INFO: THE RPTR STATED THE #1 ENG WAS PREVIOUSLY WORKED FOR AN RPM AND OIL PRESSURE LOG RPT OF FLUCTUATING. THE RPTR SAID THE FLUCTUATION WAS NOT CORRECTED AS IT WAS PRESENT DURING THE FLT. THE RPTR STATED NO CAUSE HAS BEEN RPTED BY MAINT FOR THE 30 SECOND LOSS OF PWR ON #1 ENG. THE RPTR SAID #2 ENG EXPERIENCED A FAILED ENG DRIVEN FUEL PUMP.
