Aztecs in PNG
SIL in Aiyura had an Aztec that crashed in Nadzab, enroute from Lae to Aiyura in 1975. I don't recall the model or callsign.
One of the engines caught on fire due to a fuel line coming adrift and spraying fuel inside the cowling, not 100% sure of that but it was something similar. Unfortunately all on board perished, if I recall it was 5 missionaries and the pilot, Doug Hunt. I think this may have been the worst accident for the SIL Aviation team in their long history in PNG.
