Amendment of Class D and E Airspace for the Following Texas Towns; Houston Sugar Land, TX; Alice, TX; Bay City, TX; Brenham, TX; Burnet, TX; Falfurrias, TX; Graford, TX; and Hamilton, TX
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.
Airworthiness Directives; General Electric Company Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B64, -1B64/P1, -1B64/P2, - 1B67, -1B67/P1, -1B67/P2, -1B70, -1B70/P1, -1B70/P2, -1B70/75/P1, - 1B70/75/P2, -1B70C/P1, -1B70C/P2, -1B74/75/P1, -1B74/75/P2, -1B76A/P2 turbofan engines. This proposed AD was prompted by a fracture of the fuel manifold which led to an in-flight shutdown of the engine. This proposed AD would require replacement of the outer left side signal fuel manifold with a part eligible for installation. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes
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.
Airworthiness Directives; Learjet Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Learjet Inc. Model 36A airplanes. This AD was prompted by a report indicating that an aileron cable failed on an airplane during a tension check and a determination that Model 36A airplanes were not included in AD 2005-13-36, which addresses this issue for other Learjet Inc. airplanes. This AD requires a one-time inspection of the center ball of the aileron control cables for a defective swage, and corrective actions if necessary. We are issuing this AD to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 airplanes. This proposed AD was prompted by several reports of nose wheel steering failures in service. This proposed AD would require a part verification and replacement of certain steering manifolds. We are proposing this AD to address the unsafe condition on these products.
