For example, the NDB 19 approach at CYO has a current approach chart.
There are no NOTAMs against it. But the NDB is no longer functioning.
It has been decommisioned. I don't know of any way a pilot could get
this information without a current AF/D.

Jepp publishes both chart notams, that come with updates, and Navdata
Notams, which are on a 7-day cycle, and list all nav facility notams and
outages.
