Bent aiplane

The 737’s like all airliners have shear pins fitted to their U/C’s. They are designed to fail during abnomaly high loads to protect the wing stucture and therefore the integrity of the fuel tanks. In the case of heavy landing the main trunions will fail and the gear will punch it’s way through the top of the wing (Good turn of phrase Bmused55!) but the fuel tank is forward of the forward mount and the structure that gets dammaged is the composite panel above the U/C.
It will be interesting to see the other dammage to this aircraft.

Here is a link to the video of the DC9 losing its tail….

Link doesn’t appear to work?

I’ve never heard of gear being designed to give way and serious doubt that is the case. It’s been seen before, aircraft breaking in 2 after a hard landing while the gear stands up to the punishment. There’s that footage of the DC-9 test flight landing where they snap the tail off and 5-6 years ago an EMB-145 crew snapped the tail off while landing.

What would the sheer pin allow, the gear to fall off?

I always assumed it was so that the gear would fail given a specific (and probably very high) loading to prevent it punching through the wing. Much like the Engine retainer bolts are designed to give way at a specific G loading.

Presumably the method to it is, its a lot easier to replace engines, gear and a few skin panels, than a wing, or entire fuselage.

Maybe I’m getting my wires crossed?

This airline is going to be lucky if it has a fleet by the end of the year. That’s now two aircraft written off in a very short space of time.

According to the Adamsair website, they have 30 Airbus A320’s on order…..

I will happily stand corrected.
I’m just sure I saw something about sheer pins in the upper parts of the MLG on 737s.

Even if the pilot was late on the flare, the planed should not have broken like that. The gear, if I’m not mistaken, is designed to give way at certain high loadings to prevent this sort of thing.

I reckon the fuse was weak in some way, fatigue or possibly corrosion. Too early to tell of course, but just my own personal inkling

Must have been one hell of a hard landing(s)

Mr Casey, have you been snapping planes again? 🙂

Certain reports suggest that the plane encountered windshear while on v.late finals.

Oh dear….that’s destined to become soda cans i’m afraid
