Beschrijving:
The DC-4 took off from Francistown runway 11 at 02:32. The engine temperatures started to rise, even after opening the gills. When temperatures exceeded the limit, the engines started backfiring. A left hand circuit was made to return to the airport, but the aircraft kept descending and crash-landed 3600 m short of the runway. The aircraft struck some trees and burst into flames.

Probable Cause:

PROBABLE CAUSE: Powerloss on all 4 engines due to fuel contamination. A load of Jet A1 (Avtur) fuel had been unloaded in one of the Aviation gasoline (Avgas) tanks, causing a contamination of 25-30%.
