April 20, 2017 – Federal Register Recent Federal Regulation Documents

This action proposes to modify Class E airspace extending upward from 700 feet above the surface at Dexter B. Florence Memorial Field Airport, Arkadelphia, AR. This action is necessary due to the decommissioning of the Arkadelphia non-directional radio beacon (NDB) and cancellation of the NDB approach. This proposed change would enhance the safety and management of standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. The FAA also proposes to update the airport name in the legal description from Arkadelphia Municipal Airport to Dexter B. Florence Memorial Field Airport.

We propose to adopt a new airworthiness directive (AD) for certain Siemens S.A.S. smoke detectors installed on various transport category airplanes. This proposed AD was prompted by a report that the affected smoke detectors failed an acceptance test. This proposed AD would require inspection and replacement of the affected smoke detectors. We are proposing this AD to correct the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This AD was prompted by a report of cracking at fastener holes located at a certain frame on the lower shell panel junction. This AD requires repetitive inspections of certain fastener holes, and related investigative and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
