Federal Aviation Administration November 19, 2020 – Federal Register Recent Federal Regulation Documents

This action proposes to amend the Class E airspace extending upward from 700 feet above the surface at Billy Free Municipal Airport, Dumas, AR. The FAA is proposing this action as the result of airspace reviews caused by the decommissioning of the Monticello VHF omnidirectional range (VOR) navigation aid as part of the VOR Minimum Operational Network (MON) Program.

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters. This AD requires inspecting the main rotor (M/R) hub assembly (hub) phonic wheel lock washer (lock washer) for correct installation and depending on the outcome, repairing or replacing the M/R hub. This AD was prompted by reported occurrences of M/R revolutions per minute (``NR'') sensor fluctuations. The actions of this AD are intended to address an unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC130B4 helicopters. This AD was prompted by reports of inflight detachment of the left-hand (LH) side cabin sliding doors and cases of impact damage on the main rotor blades, which were caused by degradation of the sliding door locking mechanism. This AD requires repetitive checks (measurements) of the load that operates the sliding door opening mechanism, repetitive inspections of the markings of the attachment screws for proper alignment, modifying the attachment system of the sliding door, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

This action proposes special conditions for magniX USA, Inc. (magniX), magni250 and magni500 model 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, 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.
