You're right but this was a landing accident in conditions that seem to have been below CAT1, therefore Article 39 and 40 of the ANO applies (unless you have passed the OM or 4 mile point). With no LVO capability on a Citation something else may have been going on to foce the crew into this approach?
I'd rather nor speculate too much, I hate Bizjet accidents, ours is a small world and it always feels very close to home when some of our colleagues come to grief.
Lets just hope they both fully recover.
