United Express jet makes emergency landing
A regional United Express jet bound for Chicago made an emergency landing at DuPage County Airport after pilots reported problems controlling the plane and maintaining altitude, the Federal Aviation Administration said. The flight was coming from Asheville, N.C. Ray Shoffner (www.chicagotribune.com) 기타...

I wish they had posted more info on this one... the biggest problem is that he was not able to maintain altitude... Based on that, my first thought would be "Stab Trim" issues....
At least they did not sensationalize the article and only posted what they knew...

So let me see if I have this right....you made 2 posts...one about a Flap Fail and another about Stab Trim issues but you are glad they didn't sensationalize the problem AND wish they had published more information. Can't have your peanuts and eat them too...
Yeah... the 2nd was after I read the 2nd article... You cannot edit and when you get better information, I updated accordingly...
This was originally posted back on Monday. It landed at DuPage; all safe and bused to ORD. End of story. Why drag it up again. Makes it look like 2 in a row for SkyWest which ain't so.
First time that I had seen it... I searched for it before I posted it and it did not come up. For a CRJ article, it is one I would not normally miss, so I thought it was new.
CRJ of any kind is a highly used plane. With regular use, anything will break. They must be watched closely and maintained. I put clos to 1000 hours on ours last year and never had a flap fail or any major failure of that kind. To me, if something happens on a regular basis, there is a cause which needs to be found rather than just accept and go on. When we got ours, there had been a warning on flap fail that Bombardier had put out but no cure for it.
Keep in mind that your plane has very low hours and cycles... I have worked these planes with 60 to 70 thousand hours plus and especially when the weather gets cold the flaps fail for one reason or the other and when it hits a flaps fail, they stop and will not move until intervened by maintenance. The CRJ-200's have a bad history of that. In the winter months of cold weather this is very common as well as Gear Disagrees. This does seem to be unique to the CRJ-200 and earlier, but the CRJ-700's and later doe not have the same problem. Bombardier found the problem and rectified it. I think it has a lot to do with the Flap Drive Transmissions and the BPSU's (Brake Position Sensor Units). When the flaps are in a failed position there is an AD that must be accomplished, and depending on the situation can be deferred for one day, but if it comes back the plane is grounded where it is at.
Like I said, the 200's are the oldest and you know as well as me that if something gets used heavy, it will eventually fail or break, regardless of mx. Bombardier found their problem and rectified it, although AD has not been fully met yet but they will get there. There will be other stuff on other planes and it goes on, keeping you in a job.LOL
That AD re-enacts itself every time a flap fail strikes.... There is no true fix for it, but a lot of airlines changes out all the flap actuators every 2 years or so and that seems to help, but still does not prevent it.
Well, the 2 year replaement cycle ain't bad. You have to consider that the flaps and all their parts are ne of the most highly used items out of all controls as they are used on every takeoff and landing and by virtue of their position, are lightweight and probably among the weakest. Gear cycle is the only other thing that comes to mind as far as usage. It is strange though that it is only on the 200 and not the rest in that line nor on AC of other mfg.
Nope, the flap problem appears to be mostly in CRJ-200... It does happen to other planes, I have heard of one happening on a boeing 737, but only 1. It is rare on other planes, but not unheard of.
From a Passenger Quote "I definitely knew we were going really, really fast" and seeing the images, I would guess a flap fail. Notice the image from the first article that the Flaps are partially extended. The CRJ-200 has a bad history of Flap Fails.
