Confidence Rating: Accident investigation report completed and information captured
A Rand Robinson KR-2 crashed on approach to Boschkop-Kitty Hawk Airport (FAKT).
According to an eyewitness at FAKT, the aircraft was observed executing a few aerobatic manoeuvres and had later joined the base leg pattern in preparation for landing on Runway 01. A second eyewitness who was located to the south of the accident site on a farm observed the aircraft at an estimated height of 800 feet (ft) above ground level (AGL) on base leg. The aircraft then made a steep turn to the left for the final approach at high speed after which the left wing broke and fell into his yard. The aircraft consequently entered a spin and crashed.
The pilot died in the crash.

Probable Cause
The pilot lost control of the aircraft after the right-wing broke off in-flight due to the aileron aerodynamic flutter.
Contributing Factor:
The aileron was under balanced to the extent of 60 kilograms per millimetre (kg/mm) residual moment.
