What to do
Affected operators must revise the airplane flight manual to include the updated limitations and operating procedures by June 21, 2023, the effective date of this directive. They must comply with these procedures for dispatch, takeoff, approach, landing, and go-around operations at all airports, especially where 5G C-Band interference is present. Continued adherence to these requirements is necessary until further FAA rulemaking or updated radio altimeter standards are issued.
Summary
The Aircraft Flight Manual - Limitations / Operating Procedures - Amendment is a final rule issued by the Federal Aviation Administration (FAA) addressing Boeing Model 747 series airplanes, including 747-100 through 747-400F variants. This amendment supersedes a previous Airworthiness Directive and updates the airplane flight manual to include new limitations and operating procedures related to interference from 5G C-Band wireless broadband signals affecting radio altimeter performance.
What changed
This amendment replaces Airworthiness Directive 2022-06-16 and requires revising the limitations section of the airplane flight manual to incorporate additional operating procedures for takeoff, instrument landing system approaches, non-precision approaches, and go-around maneuvers in the presence of 5G C-Band interference. It retains previous procedures but adds new limitations due to expanded 5G deployment across the contiguous United States.
Why it matters
This amendment is critical for aviation professionals because 5G C-Band interference can degrade radio altimeter functionality, potentially causing other airplane systems to malfunction and increasing flightcrew workload during critical phases of flight. Operators, maintenance, and compliance teams must ensure updated manuals and procedures are followed to maintain safe flight operations and regulatory compliance.
