Has there been a recent change in the airspace configuration at KFYV-- Drake Field near Fayetteville AR?
A little more googling has provided an answer -- on 12/10/18, effective 2/28/19, the extension was greatly reduced in size (and the remaining bit converted to class D) due to the decommissioning of the Drake VHF omnidirectional range (VOR) navigation aid -- see https://www.federalregister.gov/documents/2018/12/10/2018-26498/amendment-of-class-d-and-e-airspace-and-revocation-of-class-e-airspace-fayetteville-ar

I'm not sure why that airspace change was not reflected in any of these documents-- https://www.faa.gov/air_traffic/publications/airspace_amendments/

Actually, it was there, I just didn't see it because they mistakenly used the abbreviation "AK" not "AR" for Arkansas in the table.  

Nothing more need be said here--
