Aircraft collided with a parked vehicle while taxiing in poor weather conditions due to pilot distraction by road surface irregularities.

What happened

The accident occurred while the airplane was being taxied along a designated taxiway. The aircraft's left wing struck a vehicle that was stationary and parked on the taxiway surface. According to the available information, the pilot had positioned the airplane near the center of the taxiway during this maneuver.

During the taxi, environmental conditions included light snow and slush. The pilot's attention was drawn to a dip in the taxiway surface where these weather-related accumulations were present. While the pilot was focused on navigating or inspecting this specific depression in the ground, the left wing of the airplane made contact with the parked vehicle.

There were no reports of mechanical issues or system failures with the airplane prior to the incident. The event appears to be linked to situational awareness and attention management during ground operations in adverse weather.

The investigation

Examination of the accident site and the aircraft revealed damage consistent with a collision between the left wing and a stationary object. No mechanical defects were identified that would have contributed to the loss of control or navigation capability during taxi. The pilot did not report any pre-accident mechanical problems, suggesting the aircraft was airworthy and functioning normally up to the point of impact.

Findings

The primary factor in this incident was the pilot's distraction. While taxiing in conditions with light snow and slush, the pilot focused attention on a dip in the taxiway surface. This focus resulted in a loss of awareness regarding the presence of a parked vehicle on the taxiway, leading to the collision. The failure to maintain adequate visual scanning of the taxiway environment contributed directly to the accident.

Safety message

Pilots operating in conditions with reduced visibility or ground surface irregularities must maintain strict situational awareness. Distraction by environmental factors should not compromise the monitoring of the taxiway for other aircraft, vehicles, and obstacles. Effective scanning techniques are essential during all phases of ground operations.

Probable cause

The pilot's distraction while taxiing in light snow and slush, which led to a collision with a parked vehicle on the taxiway.
