FAA updates Boeing airplane rules for Canadian airspace due to 5G changes

The Federal Aviation Administration is updating airworthiness directives for certain Boeing airplanes operating in Canada. This change follows a notification from Transport Canada, the aviation authority there, about new 5G wireless broadband regulations that will increase interference with radio altimeters.
Why it matters: This rule addresses a specific safety hazard for Boeing models operating between the U.S. and Canada or within Canadian airspace. It does not change rules for domestic U.S. flights, which are governed by separate FAA directives regarding 5G interference. The practical effect is that airlines must ensure their flight crews follow updated procedures when flying into Canada after July 2026 to avoid using unreliable altitude information.
Who it affects
- Airlines operating Boeing 747-8F, 747-8 series, and 777 airplanes in Canadian airspace
