Resumo da Diretiva
A FAA está adotando uma nova diretriz de aeronavegabilidade (AD) para todos os aviões Boeing Model 707, 717 e 727; aviões Model DC-8, DC-9 e DC-10; aviões Model MD-10 e MD-11; aviões Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87) e MD-88 (descritos coletivamente no preâmbulo desta AD como MD-80); e aviões Model MD-90-30. Esta AD foi motivada pela constatação de que os altímetros de rádio não podem ser considerados confiáveis para realizar sua função pretendida se sofrem interferência de operações de banda larga sem fio na faixa de frequência 3,7-3,98 GHz (5G Banda C), e pela constatação recente de que durante aproximação, pousos e procedimentos de arredondada, como resultado desta interferência, certos sistemas da aeronave podem não funcionar adequadamente, resultando em aumento da carga de trabalho da tripulação de voo durante aproximação com o diretor de voo, autoacelerador ou piloto automático acionados. Esta AD exige a revisão das seções de limitações e procedimentos operacionais do manual de voo da aeronave (AFM) existente para incorporar procedimentos operacionais específicos para, dependendo do modelo da aeronave, aproximações por sistema de pouso por instrumentos (ILS), aproximações sem precisão, acionamento de spoilers de solo e procedimentos de arredondada e aproximações frustradas, quando na presença de interferência 5G Banda C conforme identificado por Avisos aos Aeronavegantes (NOTAMs). A FAA está emitindo esta AD para abordar a condição insegura nestes produtos.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 707, 717, and 727 airplanes; Model DC-8, DC-9, and DC-10 airplanes; Model MD-10 and MD-11 airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 (collectively described, in the preamble of this AD, as MD-80) airplanes; and Model MD-90-30 airplanes. This AD was prompted by a determination that radio altimeters cannot be relied on to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band), and a recent determination that during approach, landings, and go- arounds, as a result of this interference, certain airplane systems may not properly function, resulting in increased flightcrew workload while on approach with the flight director, autothrottle, or autopilot engaged. This AD requires revising the limitations and operating procedures sections of the existing airplane flight manual (AFM) to incorporate specific operating procedures for, depending on the airplane model, instrument landing system (ILS) approaches, non- precision approaches, ground spoiler deployment, and go-around and missed approaches, when in the presence of 5G C-Band interference as identified by Notices to Air Missions (NOTAMs). The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 707, 717, and 727 airplanes; Model DC-8, DC-9, and DC-10 airplanes; Model MD-10 and MD-11 airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 (collectively described, in the preamble of this AD, as MD-80) airplanes; and Model MD-90-30 airplanes. This AD was prompted by a determination that radio altimeters cannot be relied on to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3.98 GHz frequency band (5G C-Band), and a recent determination that during approach, landings, and go-arounds, as a result of this interference, certain airplane systems may not properly function, resulting in increased flightcrew workload while on approach with the flight director, autothrottle, or autopilot engaged. This AD requires revising the limitations and operating procedures sections of the existing airplane flight manual (AFM) to incorporate specific operating procedures for, depending on the airplane model, instrument landing system (ILS) approaches, non-precision approaches, ground spoiler deployment, and go-around and missed approaches, when in the presence of 5G C-Band interference as identified by Notices to Air Missions (NOTAMs). The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective May 23, 2022. The FAA must receive comments on this AD by July 7, 2022. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov. Follow the instructions for submitting comments. • Fax: 202-493-2251. • Mail: U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. • Hand Delivery: Deliver to Mail address above between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. Examining the AD Docket You may examine the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2022-0509; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.
