Snow big deal.

We had some aircraft do that about a month ago near where I live in Tennessee when some heavy wet snow came through.
Looks to me like it's on its wingtips! Lots of sweep on that plane.
Not enough sweep. They didn't sweep the snow off.
You don't think those surfaces can take those loads? That's exactly what the horizontal stabilizer does for a living: push down. The wings can easily take it, as well.That overnight hangar rate is not looking so high now!
I have never heard of any damage to aircraft after such an event, but those surfaces are not designed with those loads in mind.
Anyone even hear of an inspection procedure?

Good that that happened before they got farther along like the sad Atlas Air incident.

Well Kenny, I don't think anyone has even weighed 12" (the amounts I witnessed when I was flying in Canada) or more of wet snow, covering the area that the surfaces are - so how can anyone have any idea until that is weighed and compared to air loads in flight?
I think we'd have to actually estimate or weigh it, in order to proclaim damage is not possible.
I completely agree. No doubt an inspection will be in order, but I'm quite sure it will be more at the ground contact points and pressure bulkhead.. It was pretty common in Boston when I lived there to come out in the morning after snow and see planes sitting on their tailYou don't think those surfaces can take those loads?

ProbablyDo you mean National Airlines in Bagram?
I was curious, so some very rough math:
-according to what I could find the horizontal stabilizer of the Citation X has (**at most**) 100 SQ FT of area (looks to actually be much less in reality) .. assuming the heaviest of all possible "snow", pure water, and a depth of 12 inches, IE, 1 foot, that works out to about 62 lbs per square foot.. so with a surface area of 100 SQ FT with 62 lbs per square foot that works out to 6,200 lbs of force. Surely a lot of weight. But with a max takeoff weight of around 36,000 lbs the Citation X is not a small, or light plane.. so even with all that water on there the tail is only carrying 1/6 of the plane's weight.. if you factor in a forward most CG and a steep turn up to the plane's maximum certificated G load of 2.7 then that tail is under a *tremendous* amount of force.. I would bet more than 6,200 lbs. Someone with more time to do the math who has the forward loading limits can graph it out fairly easily of the force actually encountered
