Two Qantas pilots from NSW have been injured in a fatal vintage plane crash in South Africa.
A380 training captain Douglas Haywood and recently retired captain Ross Kelly were among the 19 people onboard the 1954-era Convair 340 aircraft when it crashed into a factory near Pretoria's Wonderboom Airport on Wednesday afternoon (Thursday AEST).
A South African flight engineer and a factory worker were killed in the crash.
About 20 people were injured with several trapped in the aircraft, according to private emergency service ER24.
Qantas said it was providing whatever support it could to the pilots, who were in hospital being treated for serious injuries.
"This news has shocked the Qantas pilot community and everyone's thoughts are with the families," a spokesperson said in a statement on Thursday.
South African Civil Aviation Authority said two Australians, three Dutch people and 14 South Africans made up the flight's three crew and 16 passengers.
However, Mr Kelly's wife, Lyndal, was also reportedly on board and believed to be in a stable condition, according to News Corp Australia.
The Convair 340 aircraft was on a test flight before it was to be flown to a Dutch plane museum within weeks.
In 2016, Mr Haywood and Mr Kelly, who both have at least 30 years' flying experience, flew another Convair 340 aircraft from the Pretoria airport to the Historical Aircraft Restoration Society in NSW's Illawarra region.
The pair has been members of HARS for decades, while Mr Haywood was a former Air Force pilot before joining Qantas.
South African crash investigators said two people on the ground at the time of the crash were among the injured.
