no way I would interpret that as which landing it was
Nor I. Just suggesting a possible reason for confusion as it
could be interpreted either way.
Well, it would be the airline / fleet maager which grounded them. Don't know of any law / rule / practice where either the CAA / IAA or AAIU / AAIB would action the grounding?
Nope, neither do I. What I meant to imply was just that. No point waiting for the official report as the CAA/AAIB can't undo the grounding.
you might as well either reinstate or sack
On the basis of the information available I know what I'd do.
