What happened
The pilot was in the process of picking up two other pilots who had ferried an aircraft to a paint shop. The aircraft (type not specified) had been towed to the departure end of the runway, where all necessary takeoff checks were completed.
During the takeoff roll, the aircraft failed to accelerate normally. The pilot attributed this lack of acceleration to either the condition of the sand and dirt runway or turbocharger lag. While attempting to maintain directional alignment using the rudder, the pilot noted that his heels were not on the floor, which likely resulted in the inadvertent application of brake pressure.
As the aircraft proceeded down the runway, it passed over a depression in the surface and became airborne momentarily. Upon settling back onto the runway, the aircraft bounced over a fence and struck a tree. The impact caused the right wing to separate at the wing root. Following the collision, the aircraft traveled an additional 50 feet before coming to a complete stop. The pilot reported that there were no mechanical discrepancies with the aircraft prior to the event. There were no injuries reported.
