This proposed AD would require installing protective rubber borders on the edge of the baggage avionics bay frames, 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.
Airworthiness Directives; RUAG Aerospace Services GmbH (Type Certificate Previously Held by Dornier Luftfahrt GmbH) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2007-02- 13, which applied to certain Dornier Luftfahrt GmbH (type certificate currently held by RUAG Aerospace Services GmbH) Model Dornier 228-212 airplanes. AD 2007-02-13 required inspecting the landing gear carbon brake assembly. This AD requires inspecting certain carbon brake assemblies and corrective actions if necessary. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the European Union Aviation Safety Agency (EASA) to correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as loose bolts and nuts on the landing gear carbon brake assembly. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; DG Flugzeugbau GmbH Gliders
The FAA is adopting a new airworthiness directive (AD) for all DG Flugzeugbau GmbH Models DG-808C and DG-1000T gliders. This 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 identifies the unsafe condition as damaged fuel hoses due to environmental and fatigue deterioration. This AD requires inspecting the polyurethane (PU) fuel hoses, replacing the PU fuel hoses if there is damage, and establishing a life limit for the PU fuel hoses. The FAA is issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Goodrich Externally-Mounted Hoist Assemblies
The FAA is revising a notice of proposed rulemaking (NPRM) for various model helicopters with certain part-numbered Goodrich externally-mounted hoist assemblies (hoists) installed. This action revises the NPRM by adding a figure and revising certain requirements. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since some of these actions would impose an additional burden over those in the NPRM, the agency is requesting comments on this SNPRM.
Airworthiness Directives; Arrow Falcon Exporters, Inc. (Previously Utah State University); California Department of Forestry; Firefly Aviation Helicopter Services (Previously Erickson Air-Crane Co.); Garlick Helicopters, Inc.; Global Helicopter Technology, Inc.; Hagglund Helicopters, LLC (Previously Western International Aviation, Inc.); International Helicopters, Inc.; Precision Helicopters, LLC; Robinson Air Crane, Inc.; San Joaquin Helicopters (Previously Hawkins and Powers Aviation, Inc.); S.M.&T. Aircraft (Previously US Helicopters, Inc., UNC Helicopter, Inc., Southern Aero Corporation, and Wilco Aviation); Smith Helicopters; Southern Helicopter, Inc.; Southwest Florida Aviation International, Inc. (Previously Jamie R. Hill and Southwest Florida Aviation); Tamarack Helicopters, Inc. (Previously Ranger Helicopter Services, Inc.); US Helicopter, Inc. (Previously UNC Helicopter, Inc.); West Coast Fabrication; and Williams Helicopter Corporation (Previously Scott Paper Co.) Model AH-1G, AH-1S, HH-1K, TH-1F,
The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to supersede Airworthiness Directive (AD) AD 2002-20-01, which applies to certain Model HH-1K, TH-1F, TH-1L, UH-1A, UH-1B, UH- 1E, UH-1F, UH-1H, UH-1L, and UH-1P helicopters; and Southwest Florida Aviation Model SW204, SW204HP, SW205, and SW205A-1 helicopters, manufactured by Bell Helicopter Textron, Inc. (BHTI) for the Armed Forces of the United States. The NPRM would have required removing certain serial-numbered tension-torsion (TT) straps from service, reducing the retirement life for other TT straps, and establishing a retirement life in terms of calendar time in addition to hours time-in- service (TIS) for certain other affected TT straps. The NPRM also would have added two model helicopters to the applicability of the AD. The NPRM was prompted by fatigue cracking in certain TT straps that have stainless steel filament windings and a determination that corrosion damage, which is related to calendar time, necessitated a calendar time retirement life for certain TT straps in addition to the retirement life based on hours TIS. The NPRM was also prompted by fatigue cracking in other TT straps with encased thin stainless steel plates. Since issuance of the NPRM, the FAA has re-reviewed the available information and determined that the totality of the available information does not support issuance of a final rule. Accordingly, the NPRM is withdrawn.
Airworthiness Directives; Airbus SAS Airplanes
The FAA proposes to supersede Airworthiness Directive (AD) 2020-18-04, which applies to all Airbus SAS Model A350-941 and -1041 airplanes. AD 2020-18-04 requires a one-time health check of the slat power control unit (PCU) torque sensing unit (TSU), a detailed inspection of the slat transmission systems, corrective actions if necessary, and track 12 slat gear rotary actuator (SGRA) water drainage and vent plug cleaning. Since the FAA issued AD 2020-18-04, it has been determined that the one-time health check must be repetitive instead to monitor the TSU wear, and that the water drainage and vent plug cleaning is no longer required. This proposed AD would require repetitive health checks of the slat PCU TSU, a detailed visual inspection of the slat transmission systems, and corrective actions if necessary; as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
