The FAA is considering a proposal to change 0.50 acres (future Parcel 17D) of Clear Zone Easement contained in Parcel 17B to Avigation Easement in exchange for converting 2.94 acres of land currently not controlled by the Airport Sponsor (future Parcel 36) to an Avigation Easement for approach protection. Both Parcel 17B and future Parcel 36 are owned by Crossing Rivers Health Center (and are being sold to a commercial developer) and located adjacent to Prairie du Chien Municipal Airport, Prairie du Chien, WI. The proposed release of 0.50 acres of Clear Zone Easement to Avigation Easement is not in the Runway Protection Zone (RPZ). The release of 0.50 acres from Clear Zone Easement to Avigation Easement is required to allow development on the property that is being sold by the Crossing Rivers Health Center. The conversion from Clear Zone Easement to Avigation Easement will not result in any impact to surfaces protected by Part 77 or airport design surfaces. The Clear Zone Easement was originally purchased to enable the Airport to ensure airport compatible land use. The proposed future use of 0.50 acres of the land will be a compatible land use.

In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request Office of Management and Budget (OMB) approval to renew an information collection. The collection involves information required to process a request for a Minimum Equipment List (MEL) Letter of Authorization (LOA) in accordance with certain regulations prescribing general operating and flight rules. The information to be collected is necessary because a written request is required to obtain an MEL LOA. The information collected includes only those details essential to evaluate the request, approve the MEL, and issue the LOA.

This action proposes to amend the Class D and Class E airspace and establish Class E airspace at airports in Waco, TX. The FAA is proposing this action as the result of biennial airspace reviews. The name and geographic coordinates of various airports and navigational aids would also be updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class D airspace and Class E airspace at Carbondale, IL, and Marion, IL; revoke the Class E airspace area designated as an extension to Class D airspace at Veterans Airport of Southern Illinois, Marion, IL; and establish Class E airspace extending upward from 700 feet above the surface at Southern Illinois Airport, Carbondale/Murphysboro, IL. The FAA is proposing this action as the result of airspace reviews caused by the decommissioning of the Marion very high frequency (VHF) omnidirectional range (VOR) as part of the VOR Minimal Operational Network (MON) Program. The names and geographic coordinates of the airports would also be updated to coincide with the FAA's aeronautical database.

This action proposes to amend the Class E airspace extending upward from 700 feet above the surface at Eveleth-Virginia Municipal Airport, Eveleth, MN. The FAA is proposing this action as the result of an airspace review caused by the decommissioning of the Eveleth non- directional beacon (NDB). The geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 model turbofan engines. This proposed AD was prompted by reports of cracks in the intermediate-pressure compressor (IPC) rotor 1 (R1) blades installed on certain Trent XWB model turbofan engines. This proposed AD would require initial and repetitive borescope inspections (BSIs) of the affected IPC R1 blades and, depending on the results of the inspections, replacement of all 34 IPC R1 blades. The FAA is proposing this AD to address the unsafe condition on these products.
