The Federal Aviation Administration is updating airworthiness directives for certain Boeing airplanes to address new 5G wireless interference risks in Canadian airspace. This final rule aligns U.S. requirements with changes made by Transport Canada, the aviation authority for Canada.

Why it matters: Radio altimeters are critical for safe landings, especially in poor weather. If 5G signals drown out the altimeter’s readings, pilots may lose accurate height data right before touchdown. This rule ensures that airlines have clear instructions on how to handle these situations, preventing potential runway excursions or landing accidents caused by faulty instrument data.

Who it affects

  • Airlines operating Boeing 737-8, 737-9, and 737 MAX 8 aircraft in the United States

This rule was issued by the Federal Aviation Administration; check the original document at Docket No. FAA-2026-7208 for full technical details before relying on this summary.
