What happened
On the morning of 27 August 2016, a private scenic flight departed from the Komati Gorge Lodge private airstrip in Mpumalanga Province. The flight, involving the pilot and two passengers, was intended to provide an aerial view of the surrounding nature reserve. Shortly after lifting off from the gravel and sand runway, the aircraft appeared to struggle with its climb. Witnesses observed the aircraft banking to the right, followed by a loud bang and smoke emanating from the engine. The Cessna C182Q, registration ZS-PHB, impacted a rocky hill approximately 330 meters from the end of the runway. The force of the impact and a subsequent fire destroyed the aircraft, and all three occupants sustained fatal injuries.
The investigation
SACAA AIID investigators examined the wreckage, the airfield conditions, and the pilot's credentials. The investigation noted that the airstrip was a recent construction with an uneven, soft sandy surface and a significant pothole located near the centerline. Meteorological data revealed a high-density altitude of 7,345 feet, which significantly impacts engine performance and lift. The investigation also reviewed the aircraft's weight and balance, noting the presence of two 25-litre jerry cans on board. Additionally, the pilot's medical certificate had expired in July 2016, rendering his license invalid at the time of the accident.
Findings
- The aircraft likely experienced a stall shortly after takeoff due to incorrect takeoff configuration or diminished performance.
- High-density altitude significantly reduced engine thrust and aerodynamic lift.
- The soft, sandy runway surface likely hindered the aircraft's ability to accelerate to an appropriate takeoff speed.
- The pilot was operating with an invalid medical certificate.
- The aircraft was likely improperly configured regarding flap settings or fuel mixture for the high-altitude conditions.
