FAA Orders Boeing Fixes Over 5G Signal Interference

## Summary

The FAA is updating rules for Boeing 757 and 767 airplanes because their radio altimeters can get messed up by 5G signals in Canadian airspace. Pilots will have to follow new flight manual limits to keep flights safe during landings and approaches starting July 1, 2026. This change helps avoid tricky situations but might mean extra work for flight crews and some operational limits.

## Abstract

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 757 airplanes and Model 767 airplanes. This AD was prompted by the determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G Lower C-Band) while operating in Canadian airspace, and a determination that, during approach, landings, and go-arounds, as a result of this interference, certain airplane systems may not properly function, resulting in increased flightcrew workload while on approach with the flight director, autothrottle, or autopilot engaged, which could result in reduced ability of the flightcrew to maintain safe flight and landing of the airplane. This AD requires revising the existing airplane flight manual (AFM) to incorporate limitations prohibiting certain operations requiring radio altimeter data when operating in Canadian airspace. The FAA is issuing this AD to address the unsafe condition on these products.

## Effects PRIA read

- AFM limits for Canadian flights: cost, low. If you operate Boeing Model 757 or Model 767 airplanes that are NOT radio altimeter tolerant, you must revise the airplane flight manual (AFM) to add limitations prohibiting certain operations that require radio altimeter data when operating in Canadian airspace before further flight in Canadian ai…
- Optional upgrades to remove limits: cost, high. Operators may modify airplanes to become radio altimeter tolerant to terminate the AFM limitations. The FAA lists two optional cost examples: full radio altimeter replacement up to $120,000 per airplane, or adding a filter estimated at up to $14,040 per airplane (24 work-hours x $85 = $2,040 labor…
- Upgraded altimeters exempted: benefit, medium. If your Boeing 757 or 767 airplane is a radio altimeter tolerant airplane (demonstrates the tolerances for 3.7–3.98 GHz as approved by the FAA), no AFM revision or the operating limitations in this AD are required for that airplane, and modifying a non-tolerant airplane to tolerant status terminate…
