Federal Aviation Administration July 17, 2020 – Federal Register Recent Federal Regulation Documents

This action proposes to establish Class E airspace, extending upward from 700 feet above the surface, at Granby-Grand County Airport. This action would ensure the safety and management of IFR operations at the airport.

This action proposes to amend the Class E airspace extending upward from 700 feet above the surface at Frankfort Dow Memorial Field Airport, Frankfort, MI. The FAA is proposing this action as the result of an airspace review caused by the cancellation of instrument procedures at the airport. The geographic coordinates of the airport would also be updated to coincide with the FAA's aeronautical database.

This action amends the Class E airspace extending upward from 700 feet above the surface at Baudette International Airport, Baudette, MN. This action is the result of an airspace review caused by the decommissioning of the Baudette VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database.

This action amends the Class E airspace extending upward from 700 feet above the surface at Decorah Municipal Airport, Decorah, IA. This action is the result of an airspace review caused by the decommissioning of the Waukon VHF omnidirectional range (VOR) navigation aids as part of the VOR Minimum Operational Network (MON) Program. The name of the Winneshiek Medical Center, Decorah, IA, is also being updated to coincide with the FAA's aeronautical database.

This action amends the Class D airspace and Class E surface airspace at Spirit of St. Louis Airport, St. Louis, MO, and the Class E airspace extending upward from 700 feet above the surface at St. Louis Lambert International Airport, St. Louis, MO, Spirit of St. Louis Airport, and St. Charles County Smartt Airport, St. Charles, MO, and removes St. Louis Regional Airport, Alton/St. Louis, IL. This action is the result of airspace reviews caused by the decommissioning of the Cardinal VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program; and the decommissioning of the outer markers for runways 12R, 24, and 30L at St. Louis Lambert International Airport. Airport and navigational aid names are also being updated to coincide with the FAA's aeronautical database.

The FAA proposes to supersede Airworthiness Directive (AD) 2015-22-08, which applies to all Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes. The FAA also proposes to supersede AD 2018-17-19, which applies to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, - 113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, -233, -251N, and -271N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and - 271N airplanes. The FAA also proposes to supersede AD 2019-19-15, which applies to certain Airbus SAS Model A318 series airplanes; Model A319- 111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, -233, -251N, and -271N airplanes; and Model A321 series airplanes. AD 2019-19-15 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2019-19-15, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, 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 adopt a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-550 and EMB-545 airplanes. This proposed AD was prompted by reports of cracks, delamination, and failure of the flight deck side windows during certification fatigue tests. This proposed AD would require repetitive inspections of the flight deck side windows for any cracking or delamination, corrective action if necessary, and eventual replacement of the windows, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

These special conditions are issued for Textron Aviation Inc. (Textron) Model 550, 560, and 560XL airplanes. These airplanes, as modified by Avidyne Corporation, 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 Avidyne Corporation avionics that allow internal connection to previously isolated data networks, which are connected to systems that perform functions required for the safe operation of the airplane. This feature creates a potential for unauthorized persons to access the aircraft-control domain and airline information-services domain, and presents security vulnerabilities related to the introduction of computer viruses and worms, user errors, and intentional sabotage of airplane electronic assets (networks, systems, and databases). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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.
