737 Fleet Must Update Manuals for Canadian 5G Zones

Published Date: 6/30/2026

Rule

Summary

Starting July 1, 2026, all Boeing 737-8, 737-9, and 737-8200 planes must update their flight manuals to avoid using radio altimeter data when flying in Canadian airspace. This change stops 5G signals from messing with important landing and takeoff systems, keeping flights safer and preventing runway mishaps. Pilots and airlines should act fast to follow these new rules and send feedback by August 14, 2026.

Analyzed Economic Effects

3 provisions identified: 1 benefits, 1 costs, 1 mixed.

Options to remove AFM limits cost money

Operators may eliminate the AFM operating limitations by modifying a non-radio altimeter tolerant airplane to a radio altimeter tolerant configuration. Optional modification costs listed include up to $120,000 for radio altimeter replacement, or up to $14,040 for a filter-addition option (24 work-hours plus $12,000 parts).

No action for tolerant airplanes

If a Boeing 737-8, 737-9, or 737-8200 is determined to be a radio altimeter tolerant airplane using an FAA-approved method, no actions are required by this AD and the AFM limitations do not apply. The AD states that airplanes already demonstrated tolerant performance under the 3.7–3.98 GHz criteria need not comply with the AFM revisions.

Must revise AFM before flying to Canada

Starting July 1, 2026, all Boeing 737-8, 737-9, and 737-8200 airplanes that are not radio altimeter tolerant must have their airplane flight manual (AFM) revised before any further flight in Canadian airspace. The FAA estimates the AFM revision takes 1 work-hour at $85 per airplane and that up to 832 U.S.-registered airplanes are in the affected fleet.
