FAA Issues Radio Altimeter Upgrade Mandate - Aviation Week

Detected July 25, 2026 · in Aviation Maintenance & Airworthiness (FAA)

FAA mandates upgrade of radio altimeters to mitigate 5G interference risks, affecting operators and repair stations.

Aforeworn detected this change in the Aviation Maintenance & Airworthiness (FAA) space on July 25, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated High urgency. Part 145 repair stations, Part 135/121 operators, flight schools, corporate flight departments should confirm how it applies to their specific situation before acting. There is a time constraint attached: Compliance dates vary by aircraft type; typically within 30-90 days of AD effective date. Check specific AD for your fleet.. Acting after that point can mean penalties, a lapsed licence, or lost eligibility — exactly the kind of surprise Aforeworn exists to prevent. Aforeworn monitors Aviation Maintenance & Airworthiness (FAA) continuously and turns every detected change into a plain-English briefing like this one, so you always know first.
