Air midwest crashes into hangar @ CLT??

[Beantown]

Before today, does anyone know when was the last fatal commuter turboprop flight? I can't think of one in the last three or four years. In that time, I can think of 4 or 5 major airline fatal crashes. Why is this never talked about????????? -Bean

Not to flame, but the press is reporting some valid statistics: Check it out at

I hope the formatting comes out ok.

Just because it's covered "LIVE" doesn't mean it's a story we should watch.

True.

You have to remember that the common twenty to fifty year old was raised on video games and instant gratification. As Alvin Toffler described in Future Shock, we are driven in a MacLuhan-esq quest for the new, the shiny, the leading edge, the freshest fresh, and the whitest whites. Seeing something "LIVE" is a fascination all its own, like a California car chase. In some ways, the medium IS the message.

I can't condemn Fox for attempting to do something new in TV news, despite being the network that brought us Al Bundy. Apparently, they have found an audience that has tired of Jennings and friends.

I noted today (a day off for me) that ALL of the news outlets had this repetitive "LIVE" coverage.

The MOST fascinating part of the coverage happened once the fire was completely extinguished. Then, all of the news outlets went back to the tape of the wreckage with the billowing SMOKE, recorded over an hour earlier!

HHhmm...

Raytheon lists the One Engine Inoperative (OEI) rate of climb with flaps and gear retracted, and Autofeather as 670 fpm... I find it VERY hard to believe it will do better one engine inoperative with the gear hanging out and the dead engine windmilling...

Falcon Capt............Arent the figures that you gave from Raytheon predicated on a standard day at MGTOW with the LH engine inop? I think that the conditions today were quite a bit better, and would certainly give better #s than the ones from their website. I would imagine that they did not have a full bag of gas, and I would guess 10% of them were coming back to Charlotte tonight, and maybe another 20% were staying in Greer, SC for the night, so not a whole lot of baggage. So, with one engine out, the gear out, and T/O flaps, I bet with today's conditions, 1000FPM would not be out of reach, if they did in fact loose an engine...Your thoughts? BTW, that 900EX is one bad dude!!!!

Spent many nights in Mesas 1900's doing training, I can tell you are not getting 1000'/min with a prop windmilling and the gear hanging, at least not in a brand new D-model.

LrBob,

Your post shows exceptionally poor taste. You should be ashamed for your crass sense of humor. I would advise that you remove the post and think before you type next time.

1900 crash

Terrible..Terrible..Terrible.
Who knows?????
First flight of the day..Still a little tired..Just wanting to get that first leg going...Who hasn't been there?
IF she did loose the left one on takeoff,all you guys and girls know how fast stuff happens. In a rush you might do something wrong accidently,like step on the wrong rudder pedal.Who hasn't been a little confused as to which engine was lost initially on failure?? God knows I have in a simulator,especially when I wasn't expecting it.
BUT I say again,what happened is all speculation at this point. I take this flight about 3 to 4 times a month.......
God bless all who perished and their families.

Well with 19 pax on board I am guessing they were probably pretty close to MGTOW... Using Raytheon's numbers below:

BOW: 10,685 lbs. (Is this even a realistic BOW for a D model? this number is from the Mfg.)
19 Pax: 3,800 lbs. (Yeah I know airlines can use 170 lbs/pax, but lets be realistic)
Baggage: 600 lbs. (Very light for 19 pax by any measure)
Fuel: that only leaves 2,035 lbs. left for fuel... Not sure what kind of fuel load they would have taken for this trip, but I can't imagine it was much less than this amount.

Lets keep in mind that gear hanging out is a huge performance penalty (although it helps to slightly reduce Vmc due to the lowered CG and the directional stability extended gear adds)

Also another huge performance penalty would be the windmilling prop (I am NOT speculating that is what happened here, I am merely using the example from the post above which mentioned with gear down and prop windmilling the 1900 will climb at better than 1000 FPM)

Charlotte was very near ISA temp this morning (low 50°'s, ISA being 58°F at KCLT) and they are 749 ft MSL, so not at sea level either

I think in a training situation (no pax, fairly light on fuel) the 1900D would probably do 1,000 FPM with gear down and one windmilling... but I doubt under these conditions it could do anywhere near that kind of performance... My guess based on the numbers provided by Raytheon, with the gear up and autofeather working they would have been lucky to get 600 FPM...

*************************************
The above conjecture is not meant to speculate on the cause of todays unfortunate crash, it is merely meant as a discussion of aircraft performance in a non-standard operation (OEI).

My heart and thoughts go out to the families of the crew and passengers of Air Midwest Flight 5481...

Statistics are all in the details

You have to look at all the factors involved with statistics before you decide what they truly mean and the media rarely does that. It's like all of the harping about the avg. hours flown by UA crews versus SWA over the last year when, SWA didn't park 75 a/c and crews, shrink ASM's, and isn't an international airline with augmentation. Unless something has been changed recently, the stats for commuter airplane accidents include alot of stuff that most pilots typically wouldn't associate with commuter flying. Stuff like charter's and Air Taxi's in places like AS. I doubt the major US airlines would like it if the stats included all of the global airlines! Additionally if you going to compare regional vs. major accident statistics a better metric would be accidents per cycle instead of accident's per xx hours. The average stage length is much greater for the majors than the regionals which skews the stats. Sure the gap is closing with some SJ flights, but not nearly enough to make a dent on the stats.
