What happened
On 10 January 2009, a Cessna T206H, registration ZS-CLR, departed from Kornkopie Game Farm in Limpopo Province, intending to fly to Lanseria Aerodrome. The flight was conducted under Visual Flight Rules (VFR). While the aircraft was initially tracked by radar at 6,500 feet AMSL near Dwaalboom, it was later observed at a lower altitude of 5,800 feet near Pilanesberg Aerodrome. At 1049Z, the aircraft disappeared from radar surveillance.
Following the disappearance, a large-scale search and rescue operation was launched, involving various statutory and voluntary organizations. The wreckage was eventually located four days later by a civilian helicopter. The investigation revealed that the aircraft had struck level, bushy terrain in a left-wing low attitude at a steep angle. The impact and subsequent fire resulted in the death of the pilot.
The investigation
Investigators examined radar data, meteorological records, and wreckage characteristics. Radar imagery confirmed that the accident site was experiencing thunderstorms and heavy rain at the time of the disappearance. Air Traffic Control had declared Instrument Meteorological Conditions (IMC) for Pilanesberg Aerodrome earlier that morning due to low clouds and reduced visibility.
Analysis of the wreckage showed the aircraft hit the ground with its left wing tip first, entering a high nose-down attitude. While the engine and propeller sustained severe damage, no mechanical abnormalities were found that would suggest a pre-impact failure. The investigation also noted that the pilot was flying without a filed flight plan and was not rated for flight in IMC.
Findings
- The pilot continued the flight into adverse weather conditions characterized by rain and embedded cumulonimbus clouds.
- The pilot became spatially disoriented due to the lack of a visible horizon.
- The aircraft entered a graveyard spiral, leading to the fatal impact with the terrain.
- The pilot was not rated to operate the aircraft in IMC conditions.
