Delta CRJ900 left wing stuck the runway while performing a "go-around" maneuver due to "unstable approach"

This is evidence that a CRJ can survive a wing strike and not lose an entire wing, apparently.
 
Yes, and Further evidence that perhaps there is systemic issue with CRJ900's that make then difficult to land in cross winds without wing strike?
 
there is a big difference between touching the wing tip on the ground, and slamming an aircraft into the runway, breaking the landing gear and driving the wing into the ground.
 
I suspect the root cause of the wing coming off is related to the AD which has been issued with a very short time scale to comply.

The exceeding bank during flare and not flaring is in the same league in my book.
 
"Having conducted an approach to RWY 18L, flight crew initiated a missed approach. During the go around procedure the aircraft’s left wing impacted the runway."


The more I search, rhe more CRJ900 wing strikes I find. Examples below. I stopped adfing to list only because it is getting to be a pain to mske sure no duplicate entries. However, it seems some airports made the quick search list more than once.

Clearly we need more data to determine cause of trend, but in the last few years CRJ900's are doing a lot of 'Sparking' and wing tip indpections and repair.







 
I would suggest that you would need to look at the pilot experience profiles of those involved both Captain and First officer.

I would imagine it's a first swept wing Jet type in the USA with low experience in both seats in those roles.

Like the 737 it's short gear makes it more prone to excessive roll.

The higher gear types you can have over 15degs roll before any chance of a tip strike. I can't find any public data on the crj limit but suspect it's under 10 Deg.
 
I was wondering what roll angle was "normal". The CRJ has a pretty low wing due to the engines at the back and about 11 degrees. Not so different from the 737 due to is low gear and low slung engines

I had a look but couldn't find anything.

I know for the A220 it's 16 degs but there is a EGPWs mode 7 warning at 10 degs. To be honest 10 degs of bank below 300ft is alarming while landing even for the ex military guys.

Never been near 10degs in the SIM in the flare nevermind the real aircraft.

Max xwind would be less than 5. But to be honest I don't really look at the instruments at that point. If it looks safe out the window I am happy. If it's not I do something about it. Which is extremely rare. In fact on the A220 I haven't yet. Which is more about the quality of the training department than aircraft type.
