Narrative:

Cruising at FL390, requested FL410. At FL405 the right engine rolled back. Requested lower from center, but was told unable at that moment. Informed center that we were unable to hold altitude. Immediately cleared to FL390. Reaching FL390 told center unable to hold altitude. Center requested a 40 degree right turn and cleared us to FL310. A relight of the engine occurred at approximately FL325 and we requested a higher altitude. Center told us to continue descent to FL310. Later cleared to FL330. Supplemental information from acn 415807: while climbing through approximately FL405 (approximately 50 NM northeast of bna VOR) we had a flameout on the right engine. I called ATC and advised that we would need to return to FL390. That was approved. Around FL390, I requested FL300. The controller advised us that we would need to maintain FL390 for 1-2 mins. At that time I called the controller back and said we were unable to maintain FL390, that we had a flameout and had to continue the descent. We were given a vector of 40 degrees to the right and a descent to FL310. We were able to get a relight at approximately FL323 and advised ATC we had done so.

Original NASA ASRS Text

Title: DA20 CREW WAS FORCED TO DSND WHEN #2 ENG LOST THRUST.

Narrative: CRUISING AT FL390, REQUESTED FL410. AT FL405 THE R ENG ROLLED BACK. REQUESTED LOWER FROM CTR, BUT WAS TOLD UNABLE AT THAT MOMENT. INFORMED CTR THAT WE WERE UNABLE TO HOLD ALT. IMMEDIATELY CLRED TO FL390. REACHING FL390 TOLD CTR UNABLE TO HOLD ALT. CTR REQUESTED A 40 DEG R TURN AND CLRED US TO FL310. A RELIGHT OF THE ENG OCCURRED AT APPROX FL325 AND WE REQUESTED A HIGHER ALT. CTR TOLD US TO CONTINUE DSCNT TO FL310. LATER CLRED TO FL330. SUPPLEMENTAL INFO FROM ACN 415807: WHILE CLBING THROUGH APPROX FL405 (APPROX 50 NM NE OF BNA VOR) WE HAD A FLAMEOUT ON THE R ENG. I CALLED ATC AND ADVISED THAT WE WOULD NEED TO RETURN TO FL390. THAT WAS APPROVED. AROUND FL390, I REQUESTED FL300. THE CTLR ADVISED US THAT WE WOULD NEED TO MAINTAIN FL390 FOR 1-2 MINS. AT THAT TIME I CALLED THE CTLR BACK AND SAID WE WERE UNABLE TO MAINTAIN FL390, THAT WE HAD A FLAMEOUT AND HAD TO CONTINUE THE DSCNT. WE WERE GIVEN A VECTOR OF 40 DEGS TO THE R AND A DSCNT TO FL310. WE WERE ABLE TO GET A RELIGHT AT APPROX FL323 AND ADVISED ATC WE HAD DONE SO.
