Narrative:

Turbulence and lighting continued, still without close range radar indication. The right engine flamed out and the autoplt disengaged. We were higher than the relight envelope, and the PNF's attempted restart was unsuccessful. The aircraft handled well single engine. Despite the turbulence, I was able to maintain altitude and heading while hand-flying. I was concerned that we were still experiencing the turbulence and lightning without radar indication and therefore, without knowing where to go to escape it (besides back through what we had just experienced), and that we could just as easily lose the final engine any time. I mentally reviewed double flameout, best glide speed. The PNF stated he would focus on attempting a relight. I concurred, informed ATC of the situation and declared an emergency requesting vectors to the nearest suitable airport and advising them of WX conditions and location. ATC idented indianapolis. I concurred. ATC provided a vector and descent clearance which I executed. PNF informed the flight attendant, passenger and company of the situation and intent. We broke underneath the WX. PNF advised center cvg was as close time-wise as ind because of the high altitude. Center provided a vector to cvg and asked if we were cancelling the emergency. I replied not until the second engine was restored. The second relight attempt was successful. We cancelled the emergency with ATC and rebriefed the flight attendant, passenger and company operations representative. The remainder of the flight was uneventful. Cvg approach control asked if we desired emergency equipment. I declined.

Title: MDT ACR ACFT ENG FLAMEOUT DURING HIGH ALT CRUISE DURING TURBULENT AND LIGHTNING WX CONDITIONS. EMER DECLARED AND THEN CANCELED AFTER ENG RESTART.

Narrative: TURB AND LIGHTING CONTINUED, STILL WITHOUT CLOSE RANGE RADAR INDICATION. THE R ENG FLAMED OUT AND THE AUTOPLT DISENGAGED. WE WERE HIGHER THAN THE RELIGHT ENVELOPE, AND THE PNF'S ATTEMPTED RESTART WAS UNSUCCESSFUL. THE ACFT HANDLED WELL SINGLE ENG. DESPITE THE TURB, I WAS ABLE TO MAINTAIN ALT AND HDG WHILE HAND-FLYING. I WAS CONCERNED THAT WE WERE STILL EXPERIENCING THE TURB AND LIGHTNING WITHOUT RADAR INDICATION AND THEREFORE, WITHOUT KNOWING WHERE TO GO TO ESCAPE IT (BESIDES BACK THROUGH WHAT WE HAD JUST EXPERIENCED), AND THAT WE COULD JUST AS EASILY LOSE THE FINAL ENG ANY TIME. I MENTALLY REVIEWED DOUBLE FLAMEOUT, BEST GLIDE SPD. THE PNF STATED HE WOULD FOCUS ON ATTEMPTING A RELIGHT. I CONCURRED, INFORMED ATC OF THE SIT AND DECLARED AN EMER REQUESTING VECTORS TO THE NEAREST SUITABLE ARPT AND ADVISING THEM OF WX CONDITIONS AND LOCATION. ATC IDENTED INDIANAPOLIS. I CONCURRED. ATC PROVIDED A VECTOR AND DSCNT CLRNC WHICH I EXECUTED. PNF INFORMED THE FLT ATTENDANT, PAX AND COMPANY OF THE SIT AND INTENT. WE BROKE UNDERNEATH THE WX. PNF ADVISED CTR CVG WAS AS CLOSE TIME-WISE AS IND BECAUSE OF THE HIGH ALT. CTR PROVIDED A VECTOR TO CVG AND ASKED IF WE WERE CANCELLING THE EMER. I REPLIED NOT UNTIL THE SECOND ENG WAS RESTORED. THE SECOND RELIGHT ATTEMPT WAS SUCCESSFUL. WE CANCELLED THE EMER WITH ATC AND REBRIEFED THE FLT ATTENDANT, PAX AND COMPANY OPS REPRESENTATIVE. THE REMAINDER OF THE FLT WAS UNEVENTFUL. CVG APCH CTL ASKED IF WE DESIRED EMER EQUIP. I DECLINED.
