Federal Aviation Administration October 31, 2022 – Federal Register Recent Federal Regulation Documents

The FAA proposes to rule and invites public comment on the request to release and sell two parcels, 2.69 acres and 5.13 acres respectively, of federally obligated airport property at the Malden Regional Airport & Industrial Park (MAW), Malden, Missouri.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-08-02, which applies to all Safran Helicopter Engines, S.A. (Safran) Arriel 2D and Arriel 2E model turboshaft engines. AD 2021-08- 02 requires replacing certain critical parts before reaching their published in-service life limits, performing scheduled maintenance tasks before reaching their published periodicity, and performing unscheduled maintenance tasks when the engine meets certain conditions. Since the FAA issued AD 2021-08-02, Safran has revised the airworthiness limitation section (ALS) of the existing maintenance and overhaul manuals, introducing new and more restrictive instructions and maintenance tasks. This proposed AD would require revisions to the ALS of the operator's existing approved aircraft maintenance program (AMP), as applicable, 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.

This action proposes to remove Colored Federal airway A-9 due to the planned decommissioning of the Evansville, AK (EAV), Non- Directional Beacon (NDB), which provides navigation guidance for the affected route. The Evansville, AK (EAV), NDB is scheduled to be decommissioned effective on June 15, 2023.

This rule establishes, amends, suspends, or removes Standard Instrument Approach Procedures (SIAPS) and associated Takeoff Minimums and Obstacle Departure procedures (ODPs) for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

The FAA proposes to supersede Airworthiness Directive (AD) 2021-04-05, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2021-04-05 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2021-04-05, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2021-04-05 and require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

This action amends United States Area Navigation (RNAV) route T-278 in the vicinity of Sisters Island, AK, in support of a large and comprehensive T-route modernization project for the state of Alaska.
