It then became P2-PNG, then P2-PNH (both ex-Macair Porter rego's) and finally P2-CAA.
Yes, that is the aircraft. Yields fuel burn figures far lower than the POH!
P2-PNH (both ex-Macair Porter rego's)
VH-PNH (Macair) crashed in the Gulf on 9 March 1974. Also VH-PNF, another PC-6B/H2 Turbo Porter (PATAIR) crashed at Terapo on 14 December 1965.
I think VH-PNG became P2-SEZ with Talair.
