While there have been several RJ incidents recently there does not seem to be any real pattern. I can think of accidents involving the majors as well. 737 off runway in CMH, US Air in the Hudson, CAL burning in DEN, SWA in Chicago, AMR loosing a couple engines on the MDs (and by that I mean the engine separated), Quantas having a few rather large holes blown out of the side of their aircraft, BA having a 777 fall short of the runway, 757 landing on taxiway in EWR, Frontier guys falling asleep, NWA guys getting arrested for drinking, DAL having an engine come apart on TO roll(just a recent event that's all), etc.

These are all off the top of my head. Anyone that says it's happening at he regionals more isn't paying attention. I've yet to see anything that points to any anomaly in the safety records. Everything seems to be spread out pretty evenly to me.
