FAA corrects a regional code in Alaska airspace rule

The Federal Aviation Administration fixed a clerical error in a rule it published three months earlier that created controlled airspace around Birch Creek Airport in Alaska. The mistake was in the region code designation, not the airspace itself — the correction ensures the rule now points to the correct regional authority.

This is a purely administrative correction with zero structural consequence. The airspace boundaries and restrictions that were published in March 2026 are unchanged. The only thing that changed is which FAA regional office is responsible for managing it.
