What happened
On the morning of 4 February 2012, a pilot operating a Windlass Aquilla 582 microlight departed Crosswinds Airfield in Krugersdorp for a series of private scenic flights. After successfully completing an initial flight with a young passenger, the pilot departed again at approximately 0555Z, this time accompanied by a female passenger.
The flight path took the aircraft over several notable landmarks, including the Cradle of Humankind, the Lion & Rhino Park Nature Reserve, and the Sterkfontein Caves. While descending toward Tarlton Oaks, the aircraft struck high-tension power lines that were spanning an open field at a height of approximately 12 metres. The impact severed the wires and caused the aircraft to crash into rocky, grass-covered terrain roughly 50 metres beyond the wires. The collision resulted in one fatality and one serious injury.
The investigation
An investigation by the SACAA AIID examined the aircraft, the pilot's credentials, and the flight circumstances. The ZU-EGH was found to be in a serviceable condition, with no mechanical defects or engine malfunctions reported prior to the impact. Maintenance records and the aircraft's certificate of registration were all found to be in compliance with regulations.
The pilot, who held a valid National Pilot License and medical certificate, reported that he was distracted by an individual on the ground during his descent. Investigators also noted that while the pilot was familiar with the local area, the aircraft was flying at an altitude significantly below the regulatory minimum of 500 feet.
Findings
- The aircraft was operating a private scenic flight under Visual Flight Rules (VFR).
- The pilot was flying at a very low altitude, well below the required 500 feet above ground level.
- The primary cause of the accident was the collision with high-tension wires during low-level flight.
- A contributing factor was the failure to maintain a safe altitude.
