Department of Transportation December 19, 2022 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report of a thrust reverser actuation system (TRAS) deploy hose failure upon the commanded deployment of a thrust reverser. This AD requires removing each non- conforming TRAS deploy hose, and replacing it with a conforming TRAS deploy hose, as specified in a Transport Canada 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) 2018-18- 05, which applied to certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes; and AD 2020- 09-16, which applied to all ATR-GIE Avions de Transport R[eacute]gional Model ATR42-200, -300, and -320 airplanes. AD 2018-18-05 and AD 2020- 09-16 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD is prompted by a determination that additional new or more restrictive airworthiness limitations are necessary. This AD retains the requirements of AD 2020-09-16. This AD also requires revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive maintenance requirements and 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 adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-1041 airplanes. This AD was prompted by a report of a loud noise and vibration in the belly fairing (BF) access panel above the wings. This AD requires a one-time detailed inspection of the BF access panels and, depending on findings, accomplishment of applicable corrective actions, 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 superseding Airworthiness Directive (AD) 2020-18- 04, which applied to Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-18-04 required a one-time health check of the slat power control unit (PCU) torque sensing unit (TSU) for discrepancies, and corrective actions if necessary; a detailed inspection of the left-hand (LH) and right-hand (RH) slat transmission systems for discrepancies, and corrective actions if necessary; and LH and RH track 12 slat gear rotary actuator (SGRA) water drainage and vent plug cleaning (which includes an inspection for moisture). This AD was prompted by a determination that requiring modification of the PCU by replacing each affected slat PCU with a serviceable PCU (one having a different part number) is necessary. This AD continues to require the actions required by AD 2020-18-04, and also requires modification (replacement of each affected slat PCU with a slat PCU having a different part number), and revising the limitations on the installation of affected parts; 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 proposes to rule and invites public comment on the release and sale of one parcel of land at the Liberal Mid-America Regional Airport (LBL), Liberal, Kansas.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface at Torrington Municipal Airport, WY. This proposal would remove a northwest extension and a procedure turn airspace area to the east, add a southeast extension, and reduce the Class E airspace encircling the airport. This action will ensure the safety and management of instrument flight rules (IFR) operations at the airport.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-03-11, which applies to all Dassault Aviation Model FALCON 2000 airplanes. AD 2021-03-11 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2021-03- 11, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2021-03-11 and would require 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 Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

Diono LLC, (Diono), has determined that certain models of its child restraint systems do not fully comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 213, Child Restraint Systems. Diono filed two noncompliance reports dated June 22, 2022, and later amended one of the reports on August 10, 2022. Diono subsequently petitioned NHTSA on July 21, 2022, and July 22, 2022, and later amended one of the petitions on August 18, 2022, for a decision that the subject noncompliances are inconsequential as they relate to motor vehicle safety. This document announces receipt of Diono's petitions.
