Department of Transportation June 25, 2021 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AB139, AW139, and AW189 helicopters. This AD was prompted by a report of the in-flight failure of one of the three stainless steel external rings bonded to the main rotor swashplate boot. This AD requires repetitive inspections of these stainless steel external rings for corrosion, cracks, and the condition of the adhesive that bonds the rings to the main rotor swashplate boot, and corrective action if necessary, 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 adopt a new airworthiness directive (AD) for certain Williams International Co., L.L.C. (Williams) FJ44-2A, FJ44-2C, FJ44-3A, and FJ44-3A-24 model turbofan engines. This proposed AD was prompted by a report of cracks in high-pressure turbine (HPT) disk posts and failure of an HPT disk post. This proposed AD would require the removal and replacement of the affected HPT disk before reaching its new life limit. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to amend the Class D and Class E airspace at Scott AFB/MidAmerica St. Louis Airport, Belleville, IL. The FAA is proposing this action as the result of a biennial airspace review. The name of the airport would also be updated to coincide with the FAA's aeronautical database.

Notice is being given that the FAA is considering a request from the City of Lebanon, NH to change the land use from Aeronautical to Non-Aeronautical use for 7.6 acres of land at Lebanon Municipal Airport, Lebanon, NH. The land is not required for aeronautical use and can be developed as an extension of the existing business park. The expansion would create a new long term revenue source for the airport and the proceeds will be deposited in the airport's operations and maintenance account.

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 is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B64, 1B64/P1, -1B64/P2, - 1B67, -1B67/P1, -1B67/P2, -1B70, -1B70/75/P1, -1B70/75/P2, -1B70/P1, - 1B70/P2, -1B70C/P1, -1B70C/P2, -1B74/75/P1, -1B74/75/P2, -1B76/P2, - 1B76A/P2, -2B67, -2B67/P, and -2B67B model turbofan engines. This AD was prompted by a finding during an inspection by the manufacturer that two stages 6-10 compressor rotor spools in the high-pressure compressor (HPC) assembly were damaged at similar locations. Additionally, the manufacturer reported that certain stages 6-10 compressor rotor spool webs did not undergo a required fluorescent penetrant inspection (FPI) during production. This AD requires inspection of the stages 6-10 compressor rotor spool and, depending on the results of the inspection, replacement of the stages 6-10 compressor rotor spool. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes to amend Class D and Class E airspace in the south Florida area, by updating the geographic coordinates of the following airports; Fort Lauderdale-Hollywood International Airport, Miami-Opa Locka Executive Airport, (formerly Opa Locka Airport), North Perry Airport, Pompano Beach Airpark, Miami International Airport, Homestead ARB, Boca Raton Airport, Miami Executive Airport (formerly Kendall-Tamiami Executive Airport). This action would also update the geographic coordinates of the Fort Lauderdale Very High Frequency Omnidirectional Range Collocated with Distance Measuring Equipment (VOR/DME), and the QEEZY Locator Outer Marker (LOM). This action would also make an editorial change replacing the term Airport/Facility Directory with the term Chart Supplement in the legal descriptions of associated Class D and E airspace. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
