If I recall correctly the key to survival was the pilots actions in closing the live engine throttle to ensure wings level impact.
We may have just witnessed an almost identical set of circumstances in this crash - the only difference being which engine had failed.
Watching, over and over, that video linked to by OttoL does indeed suggest the aircraft was on runway heading but then skidded violently to the left. If this was indeed the case then it suggests the pilot may have reduced the power on the starboard engine so as to regain control.
The few seconds before disappearing from view certainly suggest very strongly that control had been regained. The act of extending the undercarriage (clearly visible in the video) also strongly suggests that the pilot's actions were oriented towards making the ground contact as survivable as possible.
I am wondering if the propeller refused to feather.
Question for the B200 experts regarding the valve that opens to allow oil pressure to leave the hub, thus causing the prop to feather: does the autofeather (via the solenoid) operate the same valve as the manual control (via the prop lever)?
