Narrative:

We were en route cvg-mht at 31000 ft abeam cxr when we received a flap fault caution and an aural overspd warning. The aural overspd warning went out after approximately 10 seconds. The gear/flaps icon appeared on the primary screen with 0 degree flaps and the flight control page showed amber boxed flaps, 0 degrees. The flaps fault checklist was performed. I contacted atl radio and got a phone patch to dispatch maintenance. We were directed over several conversations to try and correct the fault to no avail. Dispatch and I discussed options (ie, returning to cvg, continuing to mht, or diverting to another airport). We looked at the WX performance for mht and prepared for landing. The flight attendant was briefed. I elected to have the fire rescue trucks standing by as a precaution. I briefed the passenger as to our situation, the differences they could expect in the landing technique, and that the emergency equipment would be standing by as a precaution. The checklists were performed. The landing went as planned.

Title: FLC OF AN MDT LANDED WITH NO FLAPS DUE TO FLAP WARNING INDICATION. EMER EQUIP STANDBY.

Narrative: WE WERE ENRTE CVG-MHT AT 31000 FT ABEAM CXR WHEN WE RECEIVED A FLAP FAULT CAUTION AND AN AURAL OVERSPD WARNING. THE AURAL OVERSPD WARNING WENT OUT AFTER APPROX 10 SECONDS. THE GEAR/FLAPS ICON APPEARED ON THE PRIMARY SCREEN WITH 0 DEG FLAPS AND THE FLT CTL PAGE SHOWED AMBER BOXED FLAPS, 0 DEGS. THE FLAPS FAULT CHKLIST WAS PERFORMED. I CONTACTED ATL RADIO AND GOT A PHONE PATCH TO DISPATCH MAINT. WE WERE DIRECTED OVER SEVERAL CONVERSATIONS TO TRY AND CORRECT THE FAULT TO NO AVAIL. DISPATCH AND I DISCUSSED OPTIONS (IE, RETURNING TO CVG, CONTINUING TO MHT, OR DIVERTING TO ANOTHER ARPT). WE LOOKED AT THE WX PERFORMANCE FOR MHT AND PREPARED FOR LNDG. THE FLT ATTENDANT WAS BRIEFED. I ELECTED TO HAVE THE FIRE RESCUE TRUCKS STANDING BY AS A PRECAUTION. I BRIEFED THE PAX AS TO OUR SIT, THE DIFFERENCES THEY COULD EXPECT IN THE LNDG TECHNIQUE, AND THAT THE EMER EQUIP WOULD BE STANDING BY AS A PRECAUTION. THE CHKLISTS WERE PERFORMED. THE LNDG WENT AS PLANNED.
