What to do
Operators of Boeing 757 and 767 airplanes must revise their airplane flight manuals to incorporate the updated limitations and operating procedures as specified by this amendment. These revisions must be implemented by June 30, 2023, to ensure compliance with the new safety requirements addressing 5G C-Band interference. Flight crews should follow the updated procedures during dispatch, approach, landing, and go-around operations.
Summary
The Aircraft Flight Manual - Limitations / Operating Procedures - Amendment is a final rule issued by the Federal Aviation Administration (FAA) addressing Boeing Model 757 and 767 airplanes. This amendment supersedes previous airworthiness directives and updates the airplane flight manual (AFM) to include specific operating procedures related to interference from 5G C-Band wireless broadband signals affecting radio altimeters and related systems.
What changed
This amendment supersedes AD 2022-04-05 and requires revising the limitations and operating procedures sections of the AFM to incorporate updated procedures for landing distance calculations, instrument landing system (ILS) approaches, non-precision approaches, speedbrake deployment, and go-around and missed approaches due to 5G C-Band interference. The updated requirements reflect the expanded deployment of 5G C-Band base stations across the contiguous United States and the associated increased risk of interference.
Why it matters
This amendment is critical for aviation professionals because 5G C-Band interference can cause radio altimeters and other airplane systems to malfunction during critical phases of flight such as approach and landing. This interference increases flightcrew workload and may reduce the ability to safely operate the aircraft using automated flight controls. Compliance ensures continued safe flight operations and mitigates risks associated with new wireless broadband deployments.
