What happened
During the initial phase of the takeoff roll, the aircraft began to drift toward the left boundary of the paved surface. The pilot recognized this deviation and initially reduced engine power in an effort to manage the situation. However, rather than aborting the takeoff, the pilot reapplied full power and decided to continue the departure sequence.
As the aircraft accelerated, the pilot attempted to maneuver the airplane back toward the centerline of the runway. These control inputs resulted in a loss of directional control. The aircraft subsequently departed the paved surface on the right side and impacted a ditch located adjacent to the airfield.
