In the first picture with the tail
http://www.pprune.org/5699903-post611.html there is a bigger part, looking like a main gear strut, the lower part with the wheel sheared off?
Here a picture from the whole assembly
http://commondatastorage.googleapis....al/7296126.jpg, note the three hollow connection bolts, which can also bee seen on the crash picture if you zoom into it.
Would that tell us something concerning the way of first impact?
