So anyway ….. QSK? provides a logical and practically reasonable explanation for the apparent lack of mutual understanding, between Australia and New Zealand, as to which of them is responsible for providing what services and where.
I think the responsibility for providing the FIS for YSNF "fell through the cracks" between the Australian and NZ civil aviation agencies when the Norfolk Island FSU closed.
So, Australia used to provide an FSU on Norfolk Island. That makes sense: Norfolk Island is part of Australia.
And the NZ AIP references would appear to imply that NZ still thinks the FIS responsibility for Norfolk Island lies with Australia.
That makes sense: Norfolk Island is part of Australia.
Is anyone aware of or able to point to the agreement with NZ in which NZ promised to take over FIS responsibility for Norfolk Island?
It's this issue that requires investigation and comment on by the ATSB and, if necessary, be the subject of a safety recommendation so that the appropriate MoU/LoA remedial action, as you have proposed, is implemented between the Australian and NZ agencies so that we don't have a repeat of this situation again in the future.
Hear! Hear!
