A student pilot was unable to maintain directional control during the takeoff roll of a light aircraft, resulting in contact with two parked planes due to unfamiliarity with the controls.

What happened

During the initial phase of the takeoff roll, the flight crew attempted to accelerate the aircraft for departure. As the pilot advanced the throttle to full power, the aircraft began to drift toward the left side of the runway. The pilot recognized the deviation and applied right rudder input in an effort to correct the heading and maintain the centerline.

Despite these corrective efforts, the aircraft continued to roll and yaw to the left. The pilot was unable to regain directional control before the airframe made contact with two aircraft that were parked nearby on the ramp or apron area. The incident concluded with the loss of control during this critical phase of flight.

The investigation

Post-accident analysis focused on the pilot's handling of the aircraft during the high-power portion of the takeoff roll. Investigators examined the sequence of events leading to the deviation from the runway centerline and the subsequent collision with stationary objects.

Findings

The primary factor contributing to the accident was determined to be the student pilot's lack of experience and familiarity with the specific aircraft being flown. The pilot could not adequately counteract the left-turning tendencies or control inputs required during the takeoff roll, leading to a loss of directional control.

Probable cause

The student pilot's loss of directional control during takeoff due to unfamiliarity with the aircraft.
