Federal Aviation Administration August 24, 2020 – Federal Register Recent Federal Regulation Documents

These special conditions are issued for the Safran Helicopter Engines, S.A. (Safran Helicopter Engines), Arrano 1A turboshaft engine model. This engine model will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for aircraft engines. This design feature is a 30-minute All Engines Operating (AEO) power rating. 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.

This action amends Class E surface airspace, and Class E airspace extending upward from 700 feet above the surface at Boone County Airport, Harrison, AR, due to the decommissioning of the (HRO) RWY 36 Outer Marker (OM) and Compass Locator and cancellation of associated approaches. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations in the area. This action also updates the airport's designator by removing the city from the second line of the header.
