What happened
On 19 November 2021, a Cessna 172H aircraft, registration ZS-IRA, was performing circuit training at Lanseria Airport. The flight was being conducted under visual flight rules for private operations. After successfully completing an initial touch-and-go maneuver on Runway 07, the pilot was on the downwind leg of a second circuit when air traffic control reported an increase in wind velocity to 16 knots from 3/0 degrees.
In response to the changing wind conditions, the pilot decided to abort the circuit and perform a full-stop landing. During the final approach, the pilot noted that the aircraft was unstable, maintaining a speed of 65 knots against a significant crosswind component of approximately 15 knots. Upon touchdown, the aircraft struck the runway hard on the main wheels, causing the plane to bounce. This impact led to a loss of directional control, causing the aircraft to veer right of the runway centerline and resulting in the propeller striking the runway surface. There were 0 fatalities and 0 injuries, though the aircraft sustained minor damage to the propeller tips.
The investigation
The investigation examined the flight parameters, weather conditions, and the sequence of the landing. Records from the SA Weather Service confirmed that while the wind was initially 10 knots, it had increased significantly. The investigation focused on the pilot's decision-making regarding the approach stability and the physical mechanics of the touchdown.
Findings
- The aircraft experienced an unstable approach due to high airspeed and a strong crosswind component.
- A hard landing on the main landing gear triggered a bounce.
- The loss of directional control caused the aircraft to deviate from the runway centerline.
- The propeller sustained damage due to contact with the runway surface.
