Federal Aviation Administration February 2017 – Federal Register Recent Federal Regulation Documents

This action modifies Class D and Class E surface area airspace at Sugar Land Regional Airport, Houston Sugar Land, TX; and Class E airspace extending upward from 700 feet above the surface at Kingsville Kleberg County Airport, Alice, TX; Bay City Municipal Airport, Bay City, TX; Brenham Municipal Airport, Brenham, TX; Burnet Municipal Airport-Kate Craddock Field, Burnet, TX; Brooks County Airport, Falfurrias, TX; Possum Kingdom Airport, Graford, TX; and Hamilton Municipal Airport, Hamilton, TX. Decommissioning of non-directional radio beacons (NDBs), cancellation of NDB approaches, and implementation of area navigation (RNAV) procedures have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at these airports. Additionally, the geographic coordinates at Bay City Municipal Airport, Brenham Municipal Airport, and Brooks County Airport, as well as the name of Sugar Land Regional Airport (formerly Sugar Land Municipal/Hull Field) are being adjusted to coincide with the FAA's aeronautical database. This action does not remove Class E airspace at Horseshoe Bay Resort Airport, Austin, TX, as was proposed.

We propose to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN- 235-300, and C-295 airplanes. This proposed AD was prompted by a reported inability to extend the external handle of the emergency door from its recess due to a jammed spring mechanism. This proposed AD would require a one-time functional check of each emergency door handle, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 airplanes.
