Narrative:

In cruise at FL410, encountered clear air turbulence which caused engine flameout. Descent (of course) started, advised center of our problem and told them we were descending to get engine lit again, then got on O2 mask. Engine started at FL310. Don't know if center had any traffic conflicts or not--no mention of any. Callback conversation with reporter revealed the following: reporter able to get prompt descent clearance from ATC, so no emergency descent or emergency declared. Engine operated normally after restart and reporter stated he has heard of several cases of flame out at altitude in turbulence with this light transport.

Title: ACR WDB ENCOUNTERED TURBULENCE AT HIGH ALT CAUSING FLAME OUT OF ENGINE AND DESCENT FOR RESTART.

Narrative: IN CRUISE AT FL410, ENCOUNTERED CLEAR AIR TURB WHICH CAUSED ENG FLAMEOUT. DSCNT (OF COURSE) STARTED, ADVISED CENTER OF OUR PROB AND TOLD THEM WE WERE DSNDING TO GET ENG LIT AGAIN, THEN GOT ON O2 MASK. ENG STARTED AT FL310. DON'T KNOW IF CENTER HAD ANY TFC CONFLICTS OR NOT--NO MENTION OF ANY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR ABLE TO GET PROMPT DSCNT CLRNC FROM ATC, SO NO EMER DSCNT OR EMER DECLARED. ENG OPERATED NORMALLY AFTER RESTART AND RPTR STATED HE HAS HEARD OF SEVERAL CASES OF FLAME OUT AT ALT IN TURB WITH THIS LTT.
