What happened
On 25 September 2001, a Cessna 152, registered ZS-LSP, was conducting training maneuvers at Swartkops Aerodrome (FASK). The student pilot, operating for the Defence Flying Club, had initially departed from Runway 02 to perform exercises in the Gliding Field before returning to practice circuits and landings.
During the flight, the pilot observed a shift in wind direction that favored the use of Runway 20. Consequently, the pilot transitioned from the existing circuit to a left-hand downwind pattern for the new runway heading. While transitioning from the base leg to the final approach, the aircraft encountered severe turbulence. As the aircraft touched down, a sudden gust of wind lifted the right wing, causing the aircraft to veer toward the left side of the runway. The aircraft subsequently struck a PAPI light adjacent to the runway, resulting in the collapse of the nose gear and causing the aircraft to overturn.
The investigation
The investigation focused on the sequence of maneuvers and the meteorological conditions present during the landing phase. Investigators examined the pilot's flight path, noting the change in circuit direction prompted by the shifting winds. The inquiry also reviewed the impact of the turbulence encountered during the final approach and the specific mechanical consequences of the collision with the runway lighting equipment.
Findings
- The aircraft sustained extensive damage during the accident.
- The pilot sustained minor injuries to the lower legs.
- The primary factor in the accident was the loss of directional control during the landing phase, triggered by a wind gust that lifted the right wing and pushed the aircraft off the runway centerline.
