BE-10 PLT LOST ALT AND AIRSPD DURING #2 ENG FLAMEOUT AND RESTART.

Narrative

RETURNING FROM TETERBORO ARPT (KTEB); I WAS ALIGNED WITH THE LOC FOR ILS -23 AT KCAK. THE AUTOPLT WAS ON. MOST OF THE TRIP HAD BEEN IN CLR SKY WITH A CLOUD LAYER 5000-8000 FT BELOW. THE SKY NEAR THE ARPT WAS HAZY. THERE WAS NO PRECIPITATION OR ICING EVIDENT. THE ALT WAS HIGH BY SEVERAL THOUSAND FT. SEVERAL MI OUTSIDE THE OM I WAS GIVEN PERMISSION TO REDUCE ALT. I THROTTLED BACK TO 400-600 FT-POUNDS TORQUE; SET APCH FLAPS AND INCREASED PROPELLER SPD TO MAXIMUM TO SLOW THE PLANE. I DROPPED THE LNDG GEAR TO LOSE ALT FASTER. AUTO IGNITION SWITCHES WERE ARMED. I WAS DSNDING AT GREATER THAN 1500 FPS. AIRSPD WAS ABOUT 130 KTS. I EXPECTED NO PROB BEING ABLE TO LAND. OTHER THAN CORRECTING FOR ALT; THIS WAS A ROUTINE ILS APCH. JUST INSIDE THE OM; I SAW THE R ENG ANNUNCIATOR PANEL LIGHT FOR AUTO IGNITION GO ON. THE PROP WAS TURNING. I LOOKED AT THE R ENG GAUGES; BUT COULD SEE NO OBVIOUS PROB. I LOOKED AT AIRSPD AND SAW THAT IT WAS RAPIDLY SLOWING AND WAS UNDER 100 KTS. I PUSHED THE THROTTLE LEVERS FORWARD TO ABOUT 1200 FT-POUNDS TORQUE TO INCREASE THE SPD. THE R ENG THEN RESTARTED WITH HIGH PWR. THE RESTART PUSHED THE PLANE HARD L AND INTO A FAST DSCNT. I SWITCHED OFF THE AUTOPLT AND WAS ABLE TO CTL THE PLANE AS I BROKE OUT OF THE HAZE. I WAS GIVEN VECTORS FOR A NEW APCH; WHICH WAS EXECUTED WITHOUT FURTHER INCIDENT. I THINK THAT THE ENG PARTIALLY OR TOTALLY FLAMED OUT; FUEL POURED INTO THE ENG AND THEN; WITH AUTO IGNITION; THE ENG RESTARTED. I DO NOT KNOW THE CAUSE OF THE FLAMEOUT. MAINT IS INVESTIGATING FUEL FLOW CTL SETTINGS. IT IS POSSIBLE THAT IT WOULD BE BETTER TO EITHER HAVE THE AUTO IGNITERS 'ON' INSTEAD OF ARMED OR HAVE THEM 'OFF' IN GOOD WX CONDITIONS TO AVOID THE HIGH PWRED RESTART OF THE ENG WITH SUBSEQUENT SPIN-OUT.
