Airworthiness Directives; The Boeing Company Airplanes
What happened
The FAA adopted a new airworthiness directive (AD) for all Boeing Company Model 757 and Model 767 airplanes. This action was signed by Donald Trump and became effective on July 1, 2026. It requires revising the airplane flight manual (AFM) to include limitations that prohibit certain operations requiring radio altimeter data when flying in Canadian airspace, due to interference from 5G Lower C-Band wireless broadband operations.
Why it matters
This directive aims to prevent unsafe flight conditions on Boeing 757 and 767 airplanes by addressing potential radio altimeter interference from 5G signals. Without these changes, flight crews could face increased workload during critical phases like landing, potentially compromising the safety of the flight and landing.
