Navigation - 5G C-Band wireless Broadband Interference with Radio Altimeter System when operating in Canadian airspace - Amendment

The document titled "Navigation - 5G C-Band wireless Broadband Interference with Radio Altimeter System when operating in Canadian airspace - Amendment" is a Federal Aviation Administration (FAA) final rule airworthiness directive (AD 2026-13-15) addressing interference issues affecting radio altimeters on various Boeing aircraft models including 707, 717, 727, DC-8, DC-9, DC-10, MD-10, MD-11, MD-81 through MD-88, and MD 90-30 airplanes. This AD responds to increased 5G Lower C-Band wireless broadband interference in Canadian airspace that compromises radio altimeter reliability and the proper functioning of critical airplane systems during approach, landing, and go-around phases. The directive mandates revisions to the airplane flight manual (AFM) to restrict certain operations dependent on radio altimeter data when operating in Canadian airspace.
