Federal Aviation Administration September 14, 2021 – Federal Register Recent Federal Regulation Documents

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.

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.

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.

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.
