A chain of events?
There seems to be a classic CRM chain forming from all the pieces that are muted in this string...
Repossessed aircraft only the month before (maintenance state? when the previous owner stopped paying the bank, he probably stopped paying the maintenence some time before that)
Pilot unfamiliar with new aircraft and flying alone.
Big weather conditions - for me he was trying to get out of or being thrown around by some big weather.Would explain the rapid directional changes.
The photos show the fueslage damage to be where the emergency exit is located. Did this fail causing explosive decompression? A few seconds of useful consciousness in an unfamiliar aircraft perhaps was not enough.
If the pilot was unconcious then the aircraft could end up in all manner of positions, including a flat spin to Earth
All supposition of course. My thoughts remain with the family and friends of the victims of this very sad accident.
