Accident Details

On 20 November 2002 at approximately 0830Z, a Robinson R22 Beta helicopter (registration ZS-RIK) was involved in an accident at Buffelsdrift farm near Ellisras in the Northern Province. The pilot, a 37-year-old commercial pilot with 1001.12 total flying hours and 597.2 hours on type, was conducting a game darting exercise with one passenger. Weather conditions were fine: wind easterly at 5 knots, no cloud, temperature 25°C.

Sequence of Events

During the flight, the helicopter ran low on fuel. The pilot landed and the helicopter owner added fuel from drums. Shortly after takeoff, approximately 100 meters from the departure point, the engine began running rough and the low rotor RPM warning activated. The pilot attempted a downwind landing, but the helicopter landed hard. The landing skids collapsed, and the main rotor struck dense bush.

Investigation Findings

No on-site investigation was carried out. The approved maintenance organization recovering the helicopter reported that the fuel drums contained water contamination. Records showed the aircraft was properly maintained; the last maintenance inspection was certified on 16 September 2002 at 5323.9 airframe hours, with an additional 61.1 hours accumulated since. The pilot held a valid commercial license, type rating, medical certificate (valid until 28 February 2003), and a cull rating for game and livestock.

Damage

The accident resulted in collapsed skids and damage to the main rotor from contact with dense bush. There were no injuries to the two occupants.

Probable cause

The aircraft was refuelled with contaminated fuel.
