Federal Aviation Administration July 22, 2021 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Airbus Helicopters
Document Number: 2021-15477
Type: Proposed Rule
Date: 2021-07-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Model EC 155B and EC155B1 helicopters. This proposed AD would require replacing the main gearbox (MGB), or as an alternative, replacing the epicyclic reduction gear module for certain serial numbered planet gear assemblies installed on the MGB. This proposed AD would also require inspecting the MGB magnetic plugs, MGB filter, and oil sump for particles. Depending on the outcome of these inspections, this proposed AD would require further inspections and replacing certain parts. This proposed AD would also prohibit installing certain parts. This proposed AD was prompted by the failure of an MGB second stage planet gear. The actions of this proposed AD are intended to correct an unsafe condition on these helicopters.
Airworthiness Directives; Pacific Aerospace Limited Airplanes
Document Number: 2021-15474
Type: Proposed Rule
Date: 2021-07-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as installation of the wing leading edge tank fuel pickup assembly in a pre-stressed condition, which could cause cracks in the wing spar web or the fuel pickup assembly pipe. This proposed AD would require inspecting the angle of the support bracket on the wing leading edge tank fuel pickup assembly and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Gulfstream Aerospace Corporation Airplanes
Document Number: 2021-15473
Type: Rule
Date: 2021-07-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation (Gulfstream) Model GVII-G500 airplanes. This AD results from flap yoke fittings with design features that cause decreased fatigue life. This AD requires replacing the flap inboard and outboard yoke fitting assemblies and establishing a 20,000 flight cycle life limit for the fittings. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Pilatus Aircraft Ltd. Airplanes
Document Number: 2021-15469
Type: Proposed Rule
Date: 2021-07-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for Pilatus Aircraft Ltd. (Pilatus) Models PC-12/45, PC-12/47, and PC- 12/47E airplanes with Supplemental Type Certificate (STC) SA00634DE installed. This proposed AD was prompted by a report of strake attachment brackets and the fuselage frame failing at the upper most bracket attachment location. This proposed AD would require inspecting the strake, attachment brackets, surrounding structure, and bolts and replacing components and repairing damage if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Dassault Aviation Airplanes
Document Number: 2021-15465
Type: Rule
Date: 2021-07-22
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes and Model FALCON 2000EX airplanes. This AD was prompted by a report that non-certified ANCRA seat tracks were installed on some airplanes and that those seat tracks might not sustain required loads during an emergency landing. This AD requires replacement of certain ANCRA seat tracks with certified (Brownline) seat tracks, 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.
Proposed Amendment of Class E Airspace; Chester, SC, Lancaster, SC, Waxhaw, NC, and Lincolnton, NC
Document Number: 2021-15452
Type: Proposed Rule
Date: 2021-07-22
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to amend Class E airspace extending upward from 700 feet above the surface for Chester Catawba Regional Airport, Chester, SC; Lancaster County-McWhirter Field Airport, Lancaster, SC; JAARS-Townsend Airport, Waxhaw, NC; and Lincolnton- Lincoln County Regional Airport, Lincolnton, NC. The FAA is proposing this action as a result of the Charlotte Class B Biennial Review. This action would also update the airport's names of Chester Catawba Regional Airport, (previously Chester Municipal Airport); JAARS- Townsend Airport, (previously Waxhaw, JAARS-Townsend Airport); and Lincolnton-Lincoln County Regional Airport, (previously Lincolnton, Lincoln County Airport). In addition, this action would also update the geographic coordinates of Lancaster County-McWhirter Field Airport and Lincolnton-Lincoln County Regional Airport to coincide with the FAA's database. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area.
