What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was unable to maintain directional control on take off roll resulting in two (2) uncommanded departures from the hard surface into the grass infield borders to the left of the runway. There was no apparent correction for torque other than an attempt at diffrential braking, resulting in both mainmount tires being blown and separating from the wheel assemblies.
Aft elevator input, rapid application of power with little or no rudder authority appears to be causal. Mainmount impact on the concrete runway border(s) resulted in wing spar and wing attach fitting damage.
