Analysis

Aircraft began left drift during takeoff roll. Pilot corrected with right rudder, and aircraft veered sharply right. Aircraft did not respond to application of left rudder or increased thrust from right engine; departed runway and crashed into drainage ditch. Pilot never attempted to abort takeoff. Investigation revealed that the right wheel bearing inner and outer bushings had been interchanged allowing the brake/backing plate assembly to bind on the wheel/drum assembly. The wheel bearings had been repacked on the last annual inspection, 20 operating hours prior to accident.
