Public Notice for Waiver of Aeronautical Land-Use Assurance Bolton Field Airport, Columbus, OH
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport designated aeronautical use to non-aeronautical use and to authorize the release of 1.5411 acres of airport property for an exchange of property between the Columbus Regional Airport Authority (CRAA) and the City of Columbus. The land currently houses a fire station that will remain on the site. The land was conveyed to the City of Columbus in Deed Volume 2806, page 644 of the Recorder's Office, Franklin County, Ohio. The land was acquired by the City of Columbus with funding from Federal Grant 8-39-0026-01. There are no impacts to the airport by allowing the airport to dispose of the property. Approval does not constitute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. In exchange, the CRAA will receive a parcel of land (43.562 acres) currently being used as a golf course facility adjacent to Port Columbus International Airport. This parcel is partially located in the existing Runway Protection Zone for Runway 10R-28L and is partially located in the Runway Protection Zone for future Runway 10R-28L as indicated on the approved Airport Layout Plan (ALP) for Port Columbus International Airport. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
Airworthiness Directives; Airbus Model A300 B2 Series Airplanes, Model A300 B4 Series Airplanes, Model A310-200 Series Airplanes, Model A310-300 Series Airplanes, and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus transport category airplanes. This proposed AD would require repetitive eddy current inspections for cracks of the stiffener fittings of the fuselage at frame (FR) 12A, and corrective actions if necessary. This proposed AD also provides a terminating action for the inspections. This proposed AD results from reports of cracks on the upper attachment fitting of the stiffener fitting at FR12A. We are proposing this AD to prevent failure of the stiffener fittings, which could result in the reduced structural integrity of the floor and rods around FR12A.
Airworthiness Directives; Boeing Model 747-100B SUD, 747-200B, 747-300, 747-400, and 747-400D Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747-100B SUD, 747-300, 747-400, and 747-400D series airplanes; and Model 747-200B series airplanes having a stretched upper deck. This proposed AD would require repetitively inspecting for cracking or discrepancies of the fasteners in the tension ties, shear webs, and frames at body stations 1120 through 1220, and related investigative and corrective actions if necessary. This proposed AD results from new reports of severed tension ties, as well as numerous reports of cracked tension ties, broken fasteners, and cracks in the frame, shear web, and shear ties adjacent to tension ties for the upper deck. We are proposing this AD to detect and correct cracking of the tension ties, shear webs, and frames of the upper deck, which could result in rapid decompression of the airplane.
Airworthiness Directives; Rolls-Royce plc RB211 Trent 875, 877, 884, 884B, 892, 892B, and 895 Series Turbofan Engines
The FAA is revising an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 875, 877, 884, 884B, 892, 892B, and 895 series turbofan engines with certain part number (P/N) low pressure compressor (LPC) fan blades installed. That AD currently requires initial and repetitive ultrasonic inspections of the fan blade dovetail roots and defines a specific terminating action to the repetitive blade inspection requirements. This AD requires the same actions but clarifies the terminating action. We are issuing this AD to prevent multiple LPC fan blade failures due to cracks, which could result in uncontained engine failure and possible damage to the airplane.
