A student pilot struck a building with the left wing of an aircraft while executing a taxi turn at a fixed base operator location due to lack of practice.

What happened

The incident occurred when a student pilot initiated a left-hand turn in front of a fixed base operator facility. The intended purpose of this maneuver was to position the aircraft for taxiing toward a runway. During the execution of the turn, the pilot looked to the right side of the cockpit. This head movement coincided with the left wing of the airplane making contact with a nearby building.

The investigation

Post-acc examination revealed no mechanical anomalies or defects with the airplane that would have contributed to the incident. The primary factor identified was the student pilot's lack of experience with specific ground handling maneuvers. Specifically, the pilot had not previously practiced 180-degree turns while taxiing, which likely impaired situational awareness during the tight maneuver.

Findings

The collision resulted from a failure to maintain adequate clearance from obstacles during a low-altitude ground maneuver. The absence of prior practice with wide-angle taxi turns contributed directly to the loss of spatial awareness. No mechanical issues were found to be involved in the sequence of events.

Probable cause

The student pilot's inadequate planning and decision-making, which resulted in striking a building during a taxi turn due to insufficient practice with 180-degree turns.
