Add a fourth type of damage...
'Disassembly for hauling through the streets of Noo Joisey'. The severe tail damage was probably just that, plus a lot of the dings on the fuselage. Or, being Noo JOisey, the Crips and Bloods maybe stole the tail bling.
There has been a previous query with regard to the missing APU. Your answer below, from a US Airways Airbus Instructor.
Speaking of hitting the water:
Did I mention that the underside was shredded? It appears that the force deformed the airframe enough that the R1 door (the galley service door directly across from the passenger boarding door) was forced open! I cannot imagine what sort of force that took. You couldn't chop your way through that structure with an axe and a six-day week to do it. The APU, and its entire fire containment box was ripped loose from the mounts and was hanging underneath the airplane by a single cable. There is also a wrinkle, an airframe deformation across the top of the fuselage just a ways aft of the wings. That airplane might have looked intact but it is junk; it is beercans.
