Possibly but not necessarily. These epicyclic gears are hardened and if thrown clear, falling free and hitting rock from 2000ft it is easily conceivable that they would break apart


The forward suspension bar mounting looks to have failed under a sudden single stress event although there appears to be some signs of minor cracking or corrosion at surface edges.
Agreed but the cause of this overstress could still be due to various scenarios. Amongst these are still some where first the lower attachment of the bar came lose and then due to it being stuck somewhere while the head tilts backward could shear it off.
Admittedly with the new pieces of information we have a G-REDL scenario seems a bit more probable than other scenarios. Still, we need to wait for the experts doing their work. There is no benefit in jumping to conclusions.
