Federal Aviation Administration June 7, 2019 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 D-2 helicopters. This AD requires replacing the rescue hoist cable cut pushbutton flip guard (flip guard). This AD was prompted by reports of unintended lifting of several flip guards. We are issuing this AD to address the unsafe condition on these products.

The FAA is considering a request from Tulsa Airports Improvement Trust to change approximately 507 acres located on the east side of the airport between North Mingo Road and Highway 169 from aeronautical use to non-aeronautical use and to authorize the conversion of the airport property. The proposal consists of three parcels of land which were originally acquired under the following grants: Federal Airport Aid Program (FAAP) Nos. 9-34-032-C132 in 1963 and 3-34-032-C514 in 1965 and Airport Development Aid Program (ADAP) No.6-40-99-15 in 1978. The land comprising these parcels is outside the forecasted need for aviation development and is no longer needed for indirect or direct aeronautical use. The Airport wishes to develop this land for compatible commercial, non-aeronautical use. The Airport will retain ownership of this land and ensure the protection of Part 77 surfaces and compatible land use. The income from the conversion of these parcels will benefit the aviation community by reinvestment in the airport. Approval does not constitute a commitment by the FAA to financially assist in the conversion of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the conversion of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. 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.

This action proposes special conditions for the Airbus Model A330-300 and Model A330-900 series airplanes. These airplanes, as modified by TTF Aerospace, LLC (TTF Aerospace), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is a lower deck mobile crew rest (LD- MCR) installed in the aft cargo compartment of Model A330-300 and Model A330-900 series airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action amends Class E airspace extending upward from 700 feet above the surface in Monroe-Walton County Airport, Monroe, GA, to accommodate airspace reconfiguration due to the decommissioning of the Monroe non-directional radio beacon and cancellation of the NDB approach. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at this airport. This action also updates the geographic coordinates of this airport.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A321-111, A321-112, A321-131, A321-211, A321- 212, A321-213, A321-231 and A321-232 airplanes. This proposed AD was prompted by a quality control review, which determined that the wrong aluminum alloy was used to manufacture several structural parts. This proposed AD would require a one-time eddy current conductivity measurement of certain structural parts of the outer flaps to determine if the incorrect alloy was used, and replacement if necessary, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
