Narrative:

While on a flight from cvg to wld at FL390, we noticed a broken line of convective WX on radar near the pxv VOR. We took a course that would take us between 2 cells that were 20 mi apart. When we were abeam pxv VOR we encountered moderate turbulence and some wind shear that caused our airspeed to increase and then decrease, so we decreased the power to maintain our speed of .76 mach. After a min or so, I increased power back to normal cruise. At that point the right engine flamed out. We had to descend to FL250 for a relight at that point. We advised ATC as soon as possible of our situation and our intentions. The purpose for this flight was to repos to wld to have loaner engines removed and new engines installed. I believe the major cause of this event was a problem in the loaner engine, but also the use of air ignition might have prevented the flameout even with the engine problem.

Title: ALTDEV ALT EXCURSION TO RELIGHT 1 FLAMED OUT ENG. INFLT ENG SHUTDOWN.

Narrative: WHILE ON A FLT FROM CVG TO WLD AT FL390, WE NOTICED A BROKEN LINE OF CONVECTIVE WX ON RADAR NEAR THE PXV VOR. WE TOOK A COURSE THAT WOULD TAKE US BTWN 2 CELLS THAT WERE 20 MI APART. WHEN WE WERE ABEAM PXV VOR WE ENCOUNTERED MODERATE TURB AND SOME WIND SHEAR THAT CAUSED OUR AIRSPD TO INCREASE AND THEN DECREASE, SO WE DECREASED THE PWR TO MAINTAIN OUR SPD OF .76 MACH. AFTER A MIN OR SO, I INCREASED PWR BACK TO NORMAL CRUISE. AT THAT POINT THE R ENG FLAMED OUT. WE HAD TO DSND TO FL250 FOR A RELIGHT AT THAT POINT. WE ADVISED ATC ASAP OF OUR SIT AND OUR INTENTIONS. THE PURPOSE FOR THIS FLT WAS TO REPOS TO WLD TO HAVE LOANER ENGS REMOVED AND NEW ENGS INSTALLED. I BELIEVE THE MAJOR CAUSE OF THIS EVENT WAS A PROB IN THE LOANER ENG, BUT ALSO THE USE OF AIR IGNITION MIGHT HAVE PREVENTED THE FLAMEOUT EVEN WITH THE ENG PROB.
