This would seem to indicate loss of an engine on takeoff. I don;t know how much torque the engines on the Beech produce, but I witnessed the same thing at Beale AFB, CA involving a KC-135 (707)
Crew was doing touch an go's and somehow smacked the left wing into the runway. The impact crushed the left out board engine, and as the pilot tried to climb out the left inboard ingested all the crap stirred up. The plane then was left with no Left side power and 2 right side engines at full thrust for climb - bam right over on it's back and nose first into the ground.
