What's irksome to me about this case is that an abbreviated amendment would have triggered a new chart (plate is what I have dinner on) within about 45 days, or so. Also, "Amendment 10A" tends to get a pilot's attention during those 45 days. And, this NOTAM violated policy. It is a temporary NOTAM, and the time limit for those is 224 days. This one goes well beyond that, because the next amendment is scheduled for Feb 01, 2018.
The 224 day limit came about because some "temporary" NOTAMS were in the system for up to 10 years.
