Federal Aviation Administration March 7, 2024 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model EMB-545 and EMB-550 airplanes. This proposed AD was prompted by occurrences of premature cracks in the outer layer of certain flight deck side windows caused by interference due to manufacturing tolerances. This proposed AD would require initial and repetitive inspections of the flight deck side windows and applicable corrective actions, and would prohibit the installation of affected flight deck side windows, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD. The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes special conditions for BETA Technologies Inc. (BETA) Model H500A electric engines that operate using electrical technology installed on the aircraft, for use as an aircraft engine. These engines have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards applicable to aircraft engines. The design feature is the use of an electric motor, motor controller, and high-voltage systems as the primary source of propulsion for an aircraft. 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 the Class D and Class E airspace at Anderson, IN. This action is the result of an airspace review conducted as part of the decommissioning of the Muncie very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operating Network (MON) Program. The name of the airport is also being updated to coincide with the FAA's aeronautical database. This action brings the airspace into compliance with FAA orders to support instrument flight rule (IFR) operations.

This notice announces the FAA's intent to designate North American Flying Service Supplemental Type Certificate (STC) No. SA1-150 as abandoned and make the related engineering data available upon request. The FAA has received a request to provide engineering data concerning this STC. The FAA has been unsuccessful in contacting North American Flying Service concerning the STC. This action is intended to enhance aviation safety.
