Airworthiness Directives; Transport and Commuter Category Airplanes
What happened
The FAA adopted a new airworthiness directive (AD) for all transport and commuter category airplanes equipped with a radio altimeter, effective July 1, 2026. This AD, signed by Donald Trump, was prompted by interference from wireless broadband (5G Lower C-Band) in Canadian airspace. It requires revising the airplane flight manual to prohibit operations requiring radio altimeter data when flying in Canada.
Why it matters
This policy ensures the continued safety of flights in Canadian airspace by preventing potential malfunctions of radio altimeters caused by 5G interference. Aircraft will be restricted from certain operations when relying on radio altimeter data, which could affect flight procedures.
Who it affects
- ›Transport category airplane operators
- ›Commuter category airplane operators
- ›Pilots operating in Canadian airspace
- ›Manufacturers of radio altimeters
