I couldn’t find the thread on the Toronto crash…. Which I thought was odd… If I missed it could a mod merge it into the proper the thread

> At 1412:43.6, the right main landing gear (MLG) contacted the runway. The aircraft was in a 7.5° bank to the right with 1° of nose-up pitch and 3g vertical acceleration, at a rate of descent of approximately 1098 fpm (18.3 fps).

The original thread devolved and ended up in the Lav.

We’ll leave this in General Topics…

3Gs and 1100 fpm onto one strut. Ooph

Oct 2007 DOH with 3570TT and 764 time in type? Would this be consistent with more of a full time ground school/sim instructor role? Seems kinda low for a 18 yr tenure?

That's a lot to decompress.

Is that normal? The strut falling off?

If you plant it on one strut at 3Gs, 1100fpm, below ref, with idle thrust, maaaaaaayyyybeeee?

Sounds like a design flaw. Single point failures and whatnot. Maybe we need two struts on each side. As a backup.

I seem to remember that someone said the CRJ has published hard landing criteria unlike a lot of planes. Anyone know what that is?

Don't tell anyone about your idea. It could be a life-changing concept for you And your family if you figure out how to monetize it.

The next question… why?

I'm digging really deep, but I think it was just under 400fpm.

I'm digging really deep, but I think it was just under 400fpm.

I believe the report said that it is 600 fpm

 

[HeyEng]

Wow...facts. How crazy, eh? That sink rate...oof.
