What happened
On 03 October 2005, a Cessna 172, registration ZS-JMI, was conducting a private flight from Richards Bay Aerodrome toward a private aerodrome located near Vryheid in KwaZulu-Natal. The flight, which included the pilot and one passenger, was occurring near sunset. As the aircraft approached the destination, the pilot encountered a runway characterized by an uphill slope and the presence of high-tension wires near the threshold. During the approach, the propeller of the aircraft struck one of these wires, causing the wire to sever. Despite the impact, the aircraft was able to complete a safe landing without further complications.
The investigation
Investigators examined the circumstances surrounding the visibility and the pilot's perception during the approach. The investigation established that the pilot experienced a sudden transition from sunlight into shadow, which caused a momentary impairment of vision due to the rapid change in light intensity. The aircraft sustained minor damage, specifically scratches to the propeller spinner, but no injuries were reported for the occupants. Maintenance records were also reviewed, confirming that the aircraft's last Mandatory Periodic Inspection had been completed in June 2005 and that all relevant Airworthiness Directives and Service Bulletins were up to date.
