The FAA has proposed to adopt a new airworthiness directive for CRJ regional jets found to be suspectable of 5G interference. The FAA has found that the interference can cause “certain failure messages to be inhibited longer than intended.” The 5G network has been causing some interference issues for aircraft since 2020 , when the rollout picked up steam. In mid-2023, the FAA introduced new rules that restricted aircraft that lacked upgraded or new 5G-tolerant altimeters from conducting low-visibility landings (aircraft altimeters have been upgraded since 2022).
