Final rule; correction.

Summary

The Federal Aviation Administration (FAA) has issued a corrective amendment to a rule that created Class E airspace around the OSF St. Elizabeth Medical Center heliport in Ottawa, Illinois. The correction simply fixes a typographical mistake in the legal description of that airspace; the underlying airspace design and its purpose—to provide controlled airspace for safe helicopter operations at the medical center—remain unchanged. The rule is issued by the Department of Transportation’s FAA and primarily affects pilots, air traffic controllers, and operators who fly in the vicinity of the Ottawa heliport. By clarifying the official description, the FAA ensures that navigation charts and flight plans accurately reflect the designated airspace. The correction becomes effective on December 24, 2026. Because it is an amendment that only fixes a wording error, there is no public comment period or further procedural step required; the FAA will update its publications and databases to reflect the corrected description.
