Federal Aviation Administration June 16, 2023 – Federal Register Recent Federal Regulation Documents

The FAA proposes to supersede Airworthiness Directive (AD) 2022-18-12, which applies to all Airbus SAS Model A330-841 and -941 airplanes. AD 2022-18-12 requires installing serviceable engine electronic control (EEC) software or EEC units having the serviceable software, limiting certain parts installation configurations, and prior or concurrent modification of EEC software. Since the FAA issued AD 2022-18-12, there was a determination that engine crystal icing protection could be (temporarily) lost if an erroneous total pressure value is provided by the airplane system, which is addressed through EEC software. This proposed AD would continue to require certain actions in AD 2022-18-12 and would require adding new limitations for intermixing of certain EEC software standards and a new operational limitation for engines with certain EEC software installed, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also prohibit the installation of certain engines under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-100-1A10 airplanes. This AD was prompted by a report that a design deficiency was discovered which could allow a no-back pawl to be incorrectly installed in a horizontal stabilizer trim actuator (HSTA). This AD requires a check for part number and serial numbers of the HSTA, and if necessary, inspection of the no-back pawl installation, and corrective action. 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 DAHER AEROSPACE (type certificate previously held by SOCATA) Model TBM 700 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as interference between the emergency exit trim panel and the upholstery panel, which could result in additional effort required to open the emergency exit door. This AD requires modification of the gripping strap, which maintains the upholstery panel on the emergency exit trim panel. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is requesting public comment on the Allegheny County Airport Authority's proposal to change 48.262 acres of airport property at Pittsburgh International Airport in Pittsburgh, Pennsylvania from aeronautical to non-aeronautical use. This acreage was purchased with federal financial assistance through the Airport Development Aid Program under Grant Agreement 8-42-0081-03.

This action amends the Class D and Class E surface airspace and Class E airspace extending upward from 700 feet above the surface in Huntsville, AL, as the result of a biennial airspace evaluation. This action extends the Class E airspace extending upward from 700 feet above the surface surrounding Redstone Army Airfield (AAF) and Huntsville Executive Tom Sharp Jr. Field. The FAA will also update terminology in the Class D and Class E surface airspace descriptions for Redstone AAF.

This action proposes to establish Class E airspace extending upward from 700 feet above the surface at Grand Coulee Dam Airport, Electric City, WA, in support of the airport's transition from visual flight rules (VFR) to instrument flight rules (IFR) operations.
