Steve Heugh, a top South African aerobatic pilot and former member of the SAAF Silver Falcons aerobatic team as well as a first officer on Boeing 747s was conducting some aerobatic manoeuvres with the plane's owner, Gerald Sweidan. They were flying above the famous Vergelegen wine estate at Somerset West, when the plane suffered a structural failure and the wing came off.
Probable Cause
Whilst conducting aerobatic manoeuvres and pulling out from a dive, both wings failed and separated from the aircraft. The failure of the wing probably resulted from the removal of the spades/mass balances from the ailerons induced aileron flutter during the dive.
