FAA Expresses Concern Over Anomalies On Boeing Model 787-8, 787-9, And 787-10

The Federal Aviation Administration will require operators of Boeing 787s to take additional precautions when landing on wet or snowy runways at airports where 5G C-band service is deployed. During the two-week delay in deploying new 5G service, safety experts determined that 5G interference with the aircraft’s radio altimeter could prevent engine and braking systems from transitioning to landing mode, which could prevent an aircraft from stopping on the runway. This decision advises of the FAA’s ongoing continued operational safety activities related to 5G C-Band interference with airplane systems using radio (also known as radar) altimeter data during landi

AD 2021-26-05 Requires Revising The Existing Maintenance Or Inspection Program

The FAA is superseding Airworthiness Directive (AD) 2020-07-17, which applied to all Saab AB, Support and Services Model SAAB 2000 airplanes. AD 2020-07-17 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-07-17, it has determined that new or more restrictive airworthiness limitations are necessary. This AD retains the requirements of AD 2020-07-17 and requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety A

AD 2021-26-06 Requires Visual Inspection Of The TGB Radial Gearshaft

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GE90 model turbofan engines. This AD was prompted by two separate in-flight shutdowns (IFSDs) resulting from failure of the transfer gearbox (TGB) radial bevel gear (TGB radial gearshaft). This AD requires visual inspection of the TGB radial gearshaft and, depending on the results of the inspection, replacement of the TGB radial gearshaft. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective February 15, 2022.
