The FAA is adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd. & Co KG (RRD) Trent XWB-75, XWB- 79, XWB-79B, and XWB-84 model turbofan engines. This AD was prompted by analysis by the manufacturer of the low-pressure compressor (LPC) outlet guide vane (OGV) assembly and LPC OGV outer mount ring assembly. The analysis predicted that when the front engine mount is in the fail- safe condition, the most highly stressed LPC OGV outer mount ring assembly has a life that could be substantially less than one shop visit interval. This AD requires initial and repetitive inspections of the LPC OGV outer mount ring assembly and, depending on the results of the inspections, possible replacement of the LPC OGV outer mount ring assembly. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2017-18-17, which applies to all Airbus SAS Model A300 B4-603, A300 B4- 620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4- 622R, and A300 C4-605R Variant F airplanes. AD 2017-18-17 requires modifying certain fuselage frames and a repair on certain modified airplanes. Since AD 2017-18-17 was issued, the FAA has determined that, for certain airplanes, a rotating probe inspection must be performed prior to oversizing of the open-holes, and consequently more work is necessary for airplanes that have previously been modified. This proposed AD would continue to require the actions in AD 2017-18-17. This proposed AD would also require, for certain airplanes, an inspection to determine if rotating probe inspections were performed prior to oversizing of the open-holes, and repair if necessary, as specified in a European Union 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.

The FAA proposes to supersede Airworthiness Directive (AD) 2018-15-04, which applies to certain General Electric Company (GE) CF6- 80A, CF6-80A1, CF6-80A2, CF6-80A3, CF6-80C2A1, CF6-80C2A2, CF6-80C2A3, CF6-80C2A5, CF6-80C2A5F, CF6-80C2A8, CF6-80C2B1, CF6-80C2B1F, CF6- 80C2B2, CF6-80C2B2F, CF6-80C2B4, CF6-80C2B4F, CF6-80C2B5F, CF6-80C2B6, CF6-80C2B6F, CF6-80C2B6FA, CF6-80C2B7F, CF6-80C2D1F, CF6-80C2L1F, and CF6-80C2K1F model turbofan engines. AD 2018-15-04 requires ultrasonic inspection (UI) of high-pressure turbine (HPT) stage 1 and stage 2 disks. Since we issued AD 2018-15-04, GE determined the need to expand the population of affected disks. This proposed AD would retain the required inspections while expanding the population of affected disks. The FAA is proposing this AD to address the unsafe condition on these products.

The Federal Aviation Administration (FAA) is considering a proposal and invites public comment to change a portion of the airport from aeronautical use to non-aeronautical use at Salinas Municipal Airport (SNS), Salinas, Monterey County, California. The proposal consists of one parcel containing 13.25 acres of airport land, located outside of the airfield, south of Airport Boulevard, between Mercer Way and Skyway Boulevard, and north of Mortensen Avenue.

This action amends the Class D airspace at Fort Worth Spinks Airport, Fort Worth, TX, and the Class E airspace extending upward from 700 feet above the surface at Bourland Field, Fort Worth, TX, and Mesquite Metro Airport, Mesquite, TX, and Stephenville Clark Regional Airport, Stephenville, TX. These actions are the result of airspace reviews caused by the decommissioning of the Glen Rose VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates and names of several airports are also being updated to coincide with the FAA's aeronautical database.
