A student pilot misjudged distance to an airport fence while maneuvering for a short field takeoff, causing the left wing to strike the barrier as the instructor scanned for traffic.

What happened

During a training flight focused on short field takeoff procedures, the student pilot was responsible for maneuvering the aircraft. The objective was to position the airplane as close as possible to the end of the runway to optimize the takeoff roll. While the student managed the aircraft's positioning, the flight instructor was occupied scanning the surrounding area for potential traffic conflicts.

As the student executed a right turn near the airport boundary, they misjudged the distance between the aircraft and a chain link fence bordering the field. Consequently, the left wing of the airplane struck the fence structure. The incident occurred during the pre-takeoff maneuvering phase, highlighting a critical error in spatial awareness relative to ground obstacles.

The investigation

The examination focused on the circumstances surrounding the contact with the airport boundary infrastructure. Investigators determined that the primary issue was the student pilot's inability to accurately gauge the proximity of the aircraft to the perimeter fence during the turning maneuver. No mechanical failures or weather-related factors contributed to the event; the cause was strictly related to pilot decision-making and spatial judgment during low-level ground operations.

Probable cause

The student pilot's misjudgment of distance from the airport boundary fence during a right turn while preparing for a short field takeoff, which resulted in the left wing striking the fence.
