Incident Overview
On November 30, 2000, a Bell 407 helicopter with registration ZS-RLA was involved in a fatal accident during a private night flight. The aircraft departed from Olifantsfontein at approximately 2217Z (00:17 SAST) with the intention of landing at Duck Point in the Sasolburg area along the Vaal River. All four occupants on board were killed in the incident.
Operational Context and Occupants
The pilot-in-command, who was also the Managing Director of an international company, held a valid private license. At the time of the accident, he had accumulated 828.5 total flying hours and 150.1 hours on type. The flight carried three passengers: the pilot's wife, a business associate, and the associate's wife. The group had attended a corporate function at the St. George Hotel south of Pretoria before being driven to the departure point.
Accident Sequence and Discovery
The helicopter failed to arrive at its intended destination by 0600Z the following morning. Upon notification from the pilot's driver, an aerial search was initiated. The wreckage was located at approximately 0830Z in the Hartzenbergfontein area. GPS coordinates for the site were recorded as 26° 23’ 25” South and 027° 59’ 05” East, at an elevation of approximately 6,100 feet above mean sea level.
Meteorological Conditions and Cause
At the time of the accident, weather conditions included wind from 130 degrees at 8 knots, visibility between 1 and 3 kilometers, fog patches, and stratus clouds covering 6-7/8 of the sky at altitudes between 300 and 500 feet. The investigation concluded that the non-instrument rated pilot likely entered instrument meteorological conditions during a Visual Flight Rules (VFR) night flight. This resulted in a failure to maintain adequate terrain clearance, leading to a collision with the ground.
