Touched down out of runway at least with one mlg...possibly confused edge with centerline.All actors RNP approach certified but approach type seems to have no influence on event.
Well if your info is correct that confirm us that there was not 900m vis.
As to whethter the APP type had nothing to do , well. we'll see but one has to remember the definition of RNP 0.3. . the GPS is not designed to align you with centre line and to maintain you there , but just to align you with the runway with a precision of 0.3 of a NM orv 500 meters.
