What happened
The incident occurred while a student pilot was conducting landing practice under calm wind conditions. The pilot was positioned on final approach behind another airplane when the decision was made to execute a go-around. During this maneuver, the student's aircraft encountered wake turbulence generated by the preceding aircraft. This aerodynamic disturbance caused the aircraft to roll abruptly to the right.
Following the loss of control, the aircraft collided with two other airplanes and subsequently struck a hangar. The impact was severe enough to cause a wall of the hangar to collapse. As a result of this structural failure, a third aircraft located inside or adjacent to the hangar sustained damage.
The investigation
The investigation focused on the sequence of events leading to the collision. Key findings included the presence of wake turbulence from the preceding aircraft as the primary factor affecting the student's aircraft during the go-around phase. The abrupt right roll was identified as a direct consequence of this turbulence encounter.
