Built 1946. Delivered to Northwest A/L as NC6403 18 March 1946. To Trek Airways as ZS-CIG April 1958. On -3 Sept.1960 while en route from Cairo to Johannesburg via Entebbe, the No.2 engine caught fire at 9,500ft and could not be contained. Unable to reach the Egyptian airfield at Assiout, it was belly-landed in a sandy area of the desert near El Badary. Despite the aircraft being in flames, all 61 passengers and 6 crew escaped to safety, although the aircraft was destroyed by the fire. Fire thought to have been caused by a leak from a fuel pressure pipe, ignited by sparks from the generator.

ZS-DVJ flew its last flight into a makeshift airstrip in Warmbaths, Transvaal (now Bela-Bela, Limpopo) on 9 October 1971 for display at the Klein Kariba Resort. It was donated to the SAA Museum and moved to Johannesburg for restoration and currently on display at the museum at Rand Airport.
