PX 393 B737 facts all confirmed
In addition LVO autoland on a non LVO runway by non qualified LVO crew in an airline not approved for LVO is not only tacitly approved by the fleet office at PX but actively encouraged. Thus makes up for the lack of in flight operational support, the lack of a viable alternate and a minimum fuel operation.
IOSA is just a box ticking exercise. CASA PNG are in PX's pocket and the various aviation authorities in the region are fearful of imposing any type of sanction in case they anger the PNG government and lose access to resources or allow the Chinese more influence in PNG.
Another accident in the making.
