The board considered it "quite likely" that after the turn the captain re-tuned first VOR receiver to the ILS frequency, as the instrument was found in this state after the crash. For the final stages of flight, the aircraft was not following any VOR signal; instead the autopilot was tracking the 221° heading the navigator had set earlier during the turn. The post-accident settings of the second VOR receiver showed that it was displaying the aeroplane's position relative to Maputo and was correctly set to the Maputo VOR frequency, but was apparently not being used to guide the autopilot nor was it being monitored by the crew.
