The FAA fixed a typo in Dallas airspace rules. The rules themselves did not change.
What happened
The Federal Aviation Administration corrected a docket number error in a recent rule about Dallas airspace. This means the original rule, which defined Class D airspace around Dallas, remains exactly as intended, just with the correct administrative identifier.
Why it matters
This document is a clerical correction. It does not change any operational rules for pilots or air traffic control. The original rule about Dallas airspace stands as published, with no new effects or consequences.
The signal
There is nothing to watch. This is a correction of a clerical error.
