It happened toward the end of last yeard, October I believe without visiting my friend Google.
410 refers to Flight Level Four-One-Zero meaning 41,000 feet. That is the maximum altitude of the CRJ, of which I'm sure you're familiar as a fellow "retired" line guy

The CRJ can only make 410 when it's lightly loaded, it's ISA or colder, the moon is full and the stars are aligned properly. The accident was on a ferry flight from A to B when the pilots, the only two on board, took the airplane up to FL410.
I've got a few friends at Pinnacle, one of whom wrote a LOR for me when I went down for an interview. The captains they had during the interview process were all real great to talk to and seemed to know their stuff. The friend who wrote a letter for me is nearing his captain upgrade and has met a few knuckleheads there. Most of these guys have come from the Gulfstream Academy and if I'm not mistaken the FO on this flight was as well. Regardless, the captain being as experienced as he was to be Captain (Pinnacle required 3500TT, 1500 turbine and an exemption to that if you had 500hours in Pinnacle jets IIRC...I can't be certain I didn't take notes during the powerpoint) shouldn't have been there.
I've read the transcripts a few times and the fuel flow they're referring to isn't them trying to save money (on the line I'm told that some of the pilots are slowing down because the block times scheduled are out of whack) its them noticing the effect of the altitude on fuel flow. The higher you go in a jet the less fuel you burn because the air is less dense and to keep the ratio of fuel:air ideal you require less fuel in terms of pounds of fuel per pound of air while keeping the same volume flowing through the engine. This works for any airplane (with an exception in some cases in some turbocharged models just as a disclamer) and is a reason that jets don't go cruising around at 12,000 ft. They mention that they've seen the fuel flow at 4000lbs/hr (about 600 gallons/hr) and up there they were burning about 2000lbs/hr (roughly 300 gallons/hr). The problem you encounter with high altitude flying is your indicated airspeed decreases and if the air isn't "thick" or dense enough to hold up the jet...it'll stall. That's what happened here. They allowed the airplane to stall...even after commenting how nose high the airplane was.
This incident wouldn't have happened with passengers on board because they would have never made it to FL410 in the first place. The pilots both died in the crash. They started from 8 miles high, put all their eggs in the 'we can restart' basket and didn't make a runway. They averaged a 2000ft/min rate of decent. That's from the first master warning horn signaling engine flame out at 21:54:38 to the crash at 22:15:06. Thats 41,000 feet in 20:28. Not having flown one and asking around, you've got a short window and strict paramaters when the engines will relight using the APU. You need to meet temperature, airspeed, N1 and altitude requirements that start at only 13,000ft. 13000ft to the ground at 2000ft/min ROD is 00:06:30.
The good news is no passengers died. The good news is that there is a lot to learn from this with regard to not properly training already inexperienced crewmembers. Like Dnil mentioned...ExpressJet hires at 600hrs Total Time with 100hrs Multiengine as their published minimums. Pinnacle is 1000/150 (i think?) with preference given to Gulfstream Academy grads...a practice no longer in place following several violations of P-56 (the white house's airspace) on departure from Regan National in DC and several pilots asking for 300kts at 6,000 feet (Speed limit over the USA for civil aircraft is 250kts below 10,000 feet without ATC approval...which you don't really get unless you've got a good reason. Shedding ice in a Heavy airliner for example is a good reason)
Dnil like I said...it's not the student's fault. It's the system at the moment and it's going to get someone else killed. What quality of experience do you expect to have a 600hr "fast-track" wonder to have? I can cite ATP as an example since I went there. It's a training bubble. The kids come in with their private and are taken through the "ATP way" and get only the bare minimum qualifications they require to become bare minimum CFIs. They then (if lucky) CFI for ATP until they have 500 hours. Before reaching 500hrs...if they attend the ATP Regional Jet Standards course for a discounted price of only $1,000 (what's that when they already have a $50,000+ loan) they are permitted to interview at ExpressJet at 500 hrs. When I was there in February, the ATP instructors said they've got a 100% interview/hire rate. The cool thing is...I had more actual instrument time than the entire instructor staff combined (and I was a 750hr wonder at the time!) and during the flights they'd ask me dumbfounded why I wasn't heading to CoEx and 'bothering' with getting my CFIs.
During my time there I was also complimented on my ability to consitantly and smoothly land a seminole, my voice on the radio, situational awareness and common sense approach to talking through maneuvers. [Sarcasm mode on] It's reassuring when I fork over several thousand dollars for a program that the instructors are asking me for tips on basic airmanship.
It's also great when they proclaim that they never had to 'stoop' to work the flight line, when that was easily the most fun and educational job I've ever had. None had seen an airplane with it's cowling off, none could describe what a vaccuum pump looked like and none had any idea where the propeller accumulators were located.
There are some good people at the regionals, but there are enough bad, dorky or foolish ones that I think I'll keep doing what I'm doing and keep networking my way into a corporate job.
Best of luck to you and do all you can to learn everything you can because you're not getting the whole scoop from DCA.
Email is always open as well. Again...good luck.
