Public Notice of Surplus Property Release; Spokane International Airport, Spokane, Washington
Document Number: 2021-19796
Type: Notice
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
Notice is being given that the FAA is considering a request from the City of Spokane, Washington and the County of Spokane, Washington, to waive the surplus property requirements for approximately 2.9 acres of airport property located at Spokane International Airport, in Spokane, Washington. The subject property is located away from the aeronautical area and currently includes two existing city water reservoirs located in the southeast section of the business park. This release will allow the City and the County to sell a portion of 1 parcel of airport property to the City of Spokane and to construct an additional potable water reservoir. There will be proceeds generated from the proposed release of this property for capital improvements at the airport. The City and County will receive not less than fair market value for the property and the revenue generated from the sale will be used for airport purposes. It has been determined through study that the subject partial parcel will not be needed for aeronautical purposes.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2021-19703
Type: Proposed Rule
Date: 2021-09-14
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 determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Austro Engine GmbH Engines
Document Number: 2021-19628
Type: Proposed Rule
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2021-09-04, which applies to all Austro Engine GmbH E4 and E4P model diesel piston engines. AD 2021-09-04 requires replacing a certain oil pump as well as the oil filter and engine oil. Since the FAA issued AD 2021-09-04, the FAA determined that the requirement to replace the oil pump should be limited to only Austro Engine E4 and E4P model diesel piston engines with a certain oil pump, identified by part number (P/N) and serial number (S/N), installed. This proposed AD would require replacing a certain oil pump, the oil filter, and the engine oil installed on Austro Engine GmbH E4 and E4P model diesel piston engines. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters
Document Number: 2021-19614
Type: Proposed Rule
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. This proposed AD was prompted by a report of chafing marks on a wiring harness near the locking washer of the lateral control rod. This proposed AD would require an inspection of the wiring harness and the routing of the wiring harness and corrective actions if necessary, 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; Bell Textron Canada Limited Helicopters
Document Number: 2021-19608
Type: Proposed Rule
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede Airworthiness Directive (AD) 2021-06-06, which applies to certain Bell Textron Canada Limited Model 505 helicopters. AD 2021-06-06 requires repetitive fluorescent penetrant inspections (FPIs) of the pilot collective stick and grip assembly and revising the existing Rotorcraft Flight Manual (RFM) for your helicopter. Since the FAA issued AD 2021-06-06, the pilot collective stick and grip assembly has been redesigned. This proposed AD would retain certain requirements of AD 2021-06-06, require modifying your helicopter to include the improved pilot collective stick tube and would add a terminating action for the repetitive FPIs. This proposed AD would also prohibit installing any pilot collective stick and grip assembly unless certain requirements of this proposed AD were met. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Leonardo S.p.a. Helicopters
Document Number: 2021-19607
Type: Proposed Rule
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA is revising an earlier proposal for certain Leonardo S.p.a. Model AB139 and AW139 helicopters. This action revises the notice of proposed rulemaking (NPRM) by expanding the required actions. This proposed AD would require various inspections of certain main rotor (MR) dampers, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also require reducing the torque of the MR damper hub attachment bolts, installing a special washer, installing a certain part-numbered MR damper, and prohibit installing other part-numbered MR dampers. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, the FAA is requesting comments on this SNPRM.
Airworthiness Directives; Daher Aerospace (Type Certificate Previously Held by SOCATA) Airplanes
Document Number: 2021-19606
Type: Proposed Rule
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Daher Aerospace (type certificate previously held by SOCATA) Model TBM 700 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 a non-conforming dump switch ejecting from its slot. This proposed AD would require modifying certain dump switches. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bell Textron Canada Limited
Document Number: 2021-19605
Type: Proposed Rule
Date: 2021-09-14
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 206, 206A, 206A-1, 206B, 206B-1, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This proposed AD was prompted by reports of cracked or missing nuts on the tail rotor drive shaft (TRDS) disc pack (Thomas) couplings. This proposed AD would require removing certain nuts from service, installing newly designed nuts, and applying a specific torque and a torque stripe to each newly installed nut. This proposed AD would then require, after the installation of each newly designed nut, inspecting the torque and, depending on the inspection results, either applying a torque stripe or performing further inspections and removing certain parts from service. Finally, this proposed AD would prohibit installing any affected nut on any TRDS Thomas coupling. The FAA is proposing this AD to address the unsafe condition on these products.
