Certified to 410, Why the Problem?

CRJ Certified to 410, FLG, Why the Problem?

If the CRJ200 is certified to 41,000, why did these guys lose their engines?

I do not know, I am not flaming, I am asking an honest question, just curious.

I don't know but I seriously doubt it had anyhting to do with altitude.

Do a search on Pinnacle. There is an extensive thread on this crash in the regional forum.

I am not going to speculate, but just because an airplane is CERTIFIED to fly at 41,000 ft. doesn't mean you can fly at that altitude at ANY weight and or temperature.

The MD80 is certified to 37,000 ft., but you could never fly that high above about 125,000 lbs. GTOW is 149,000 lbs. The 80 was notorious for "falling" out of the sky if you were at weights and temperatures over what was charted for your altitude. It never happened to me, but I heard lots of pretty scary stories for the 3 years I flew it.

Thanks for the info

The CRJ-200 will only make it to FL410 under the best of circumstances. That means very light and very cold. It was ISA+9 on that night at altitude. A quick glance at the PERF charts shows that you'd have to be very light to make it to 410 at that temp. We don't know what the weight of the aircraft was that night, so we won't know whether they were within limits until the NTSB report is released.
