Federal Aviation Administration March 6, 2023 – Federal Register Recent Federal Regulation Documents

This action proposes to amend Class E airspace extending upward from 700 feet above the surface for Bomar Field/Shelbyville Municipal Airport, Shelbyville, Tennessee, as an airspace evaluation determined an update for this airport necessary. This action would also update this airport's geographic coordinates, as well as the geographic coordinates of Ellington Airport. In addition, this action would remove the Shelbyville VOR/DME from the description and update the description header.

This action proposes to establish Area Navigation (RNAV) routes T-469 and T-472 in the southwest United States. The new RNAV routes would expand the availability of the enroute structure and provide additional RNAV routing within the National Airspace System (NAS) in support of transitioning it from ground-based to satellite- based navigation.

The FAA is superseding Airworthiness Directive (AD) 2020-15- 20, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-15-20 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2020-15- 20 and requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2020-22- 16, AD 2021-16-01, and AD 2022-04-03, which applied to certain Airbus SAS Model A318, A320, and A321 series airplanes; and Model A319-111, - 112, -113, -114, -115, -131, -132, -133, -151N, and -153N airplanes. AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD continues to require the actions in AD 2020-22-16, AD 2021-16-01, and AD 2022-04-03, and also requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Cirrus Design Corporation (Cirrus) Model SF50 airplanes. This AD was prompted by reports of an accident and an incident due to uncommanded activation of the Cirrus Airframe Parachute System (CAPS) autopilot mode while in flight. This AD requires booting the avionics in configuration mode, inhibiting the CAPS autopilot, fabricating and installing information placards, revising the existing airplane flight manual (AFM) for your airplane, and revising the airworthiness limitations section (ALS) of the existing airplane maintenance manual (AMM) or Instructions for Continued Airworthiness (ICA) and your existing approved maintenance or inspection program, as applicable. For certain airplanes, this AD also requires modifying the wiring to remove the CAPS power timer functionality. The FAA is issuing this AD to address the unsafe condition on these products.
