The Federal Aviation Administration is updating an existing airworthiness directive to address interference between 5G wireless signals and airplane equipment. Specifically, this rule aligns U.S. requirements with new safety standards set by Canada after changes to their spectrum protections increase the risk of signal interference near airports.
Why it matters: This action ensures that commercial flights operating between the United States and Canada maintain consistent safety standards regarding radio interference. While most domestic U.S. operations are already covered by prior rules requiring equipment upgrades, this update closes a gap for cross-border flights where Canadian spectrum changes have increased interference risks. It is largely a technical adjustment to keep compliance requirements synchronized with neighboring airspace regulations.
Who it affects
- Airlines operating transport and commuter category airplanes in or near Canadian airspace
