Federal Aviation Administration September 15, 2021 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Fokker Services B.V. Airplanes
Document Number: 2021-19817
Type: Rule
Date: 2021-09-15
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. This AD was prompted by a report of a crack found on the forward pressure bulkhead web plate, at the edge of a bonded doubler. This AD requires a one-time inspection of the forward bulkhead for cracking, repair if necessary, and a report of inspection results, 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.
Airworthiness Directives; Airbus SAS Airplanes
Document Number: 2021-19816
Type: Rule
Date: 2021-09-15
Agency: Federal Aviation Administration, Department of Transportation
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This AD was prompted by reports of low halon concentration in the forward and aft cargo compartments due to air leakage through cargo door seals, and the certification of improved cargo door seals. This AD requires repetitive cleaning and greasing of affected cargo door seals; replacing the forward, aft, and bulk cargo compartment door seals with new seals; and installing a placard on the forward, aft, and cargo compartment doors; and for certain airplanes, implementing an operational limitation for certain routes, 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.
Airworthiness Directives; Bombardier, Inc., Airplanes
Document Number: 2021-19814
Type: Proposed Rule
Date: 2021-09-15
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. This proposed AD was prompted by a report of a wing stall (wing drop/ un-commanded roll) during a landing flare. This proposed AD would require revising the existing airplane flight manual (AFM) to incorporate a limitation and procedure for the wing anti-ice (WAI) system in order to mitigate the risk of ice accumulation on the wing leading edges. The FAA is proposing this AD to address the unsafe condition on these products.
