We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the aft pressure bulkhead is subject to widespread fatigue damage (WFD). This AD requires repetitive inspections of the aft pressure bulkhead web for any cracking, crack indications, discrepant fastener holes, and corrosion; and corrective actions if necessary. We are issuing this AD to detect and correct cracks in the aft pressure bulkhead web, which could result in an uncontrolled decompression of the fuselage.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-203 and A300 B4-2C airplanes. This AD was prompted by cracks found on pylon side panels (upper section) at rib 8. This AD requires a detailed inspection for crack indications of the pylon side panels; a high frequency eddy current (HFEC) inspection to confirm any crack indications; and repair of any cracking, or modification of the pylon side panels, and repetitive inspections and repair if necessary. We are issuing this AD to detect and correct cracking of the pylon side panels. Such cracking could result in pylon structural failure and in- flight loss of an engine.

This action establishes Class E airspace in Jetmore, KS. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures developed at Jetmore Municipal Airport, for the safety and management of Instrument Flight Rules (IFR) operations at the airport.

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4-600R series airplanes, Model A300 C4-605R Variant F airplanes, and Model A300 F4-600R series airplanes. This proposed AD was prompted by the results of a full stress analysis of the lower area of a certain frame that revealed a crack could occur in the forward fitting lower radius of a certain frame after a certain number of flight cycles. This proposed AD would require an inspection of the lower area of a certain frame radius for cracking, and corrective action if necessary. We are proposing this AD to detect and correct cracking in the forward fitting lower radius of a certain frame. Such cracking could reduce the structural integrity of the fuselage.

We are adopting a new airworthiness directive (AD) for all Gulfstream Aerospace Corporation Model G-1159, G-1159A, G-1159B, G-IV, and GV airplanes; and certain Model GIV-X and GV-SP airplanes. This AD requires a one-time replacement of the actuator end cap fitting of the main landing gear (MLG) door, and revision of the maintenance or inspection program to establish the life limit of the end cap fitting. This AD was prompted by a report of the failure of the right MLG to extend due to fatigue cracking of the end cap fitting. We are issuing this AD to prevent such cracking, which could result in depletion of the combined (left) and utility hydraulic system fluid and the nitrogen emergency blowdown system, failure of the combined (left) hydraulic system (all phases) to provide adequate hydraulic pressure, and failure of the MLG to extend when commanded.

We propose to adopt a new airworthiness directive (AD), for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This proposed AD was prompted by an analysis which determined that, for certain areas of the fuselage, the current threshold of an Airworthiness Limitations Section inspection is insufficient to detect early crack development. This proposed AD would require one time high and low frequency eddy current inspections of the affected fuselage skin for cracks and repair if necessary. We are proposing this AD to detect and correct cracks in the fuselage skin; such cracking could result in reduced structural integrity of the fuselage.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This proposed AD was prompted by a report of incidents involving fatigue cracking in transport category airplanes that are approaching or have exceeded their design service objective and a structural reevaluation by the manufacturer that identified additional structural elements that qualify as structural significant items (SSIs). This proposed AD would require revising the maintenance or inspection program, as applicable, to include inspections that will give no less than the required damage tolerance rating (DTR) for certain SSIs, and repairing any cracked structure. This proposed AD would also require inspections to detect cracks of all SSI structure, and repair if necessary. We are proposing this AD to ensure the continued structural integrity of all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes.

We propose to adopt a new airworthiness directive (AD) for various aircraft equipped with a BRP-Powertrain GmbH & Co KG (formerly Rotax Aircraft Engines) 912 A series engine. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a manufacturing defect found in certain carburetor floats. We are issuing this proposed AD to prevent the fuel supply to the affected cylinder from becoming reduced or blocked, which could cause an in-flight engine shutdown and result in a forced landing and damage to the airplane or injury to the occupants.

This action proposes to modify Class D airspace at Georgetown Municipal Airport, Georgetown, TX, and modify Class E airspace extending upward from 700 feet above the surface at Rockport Aransas County Airport, Corpus Christi, TX; Lancaster Airport, Dallas/Fort Worth, TX; Gainesville Municipal Airport, Gainesville, TX; Georgetown Municipal Airport, Georgetown, TX; (Hebbronville, TX) O.S. Wyatt Airport, Realitos, TX; and Jasper County-Bell Field, Jasper, 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 Corpus Christi International Airport; the Corpus Christi VORTAC; Aransas County Airport, Rockport, TX; Nueces County Airport, Robstown, TX; Dallas/Fort Worth International Airport, Dallas/Fort Worth, TX; McKinney National Airport, McKinney, TX; Lancaster Airport; Bourland Field Airport, Fort Worth, TX; and Jasper County-Bell Field would be adjusted to coincide with the FAA's aeronautical database. Also, the names of McCampbell- Porter Airport (formerly T.P. McCampbell Airport); McKinney National Airport (formerly Collin County Regional Airport); and Ralph M. Hall/ Rockwall Municipal Airport (formerly Rockwall Municipal Airport) would be updated to coincide with the FAA's aeronautical database.

We are adopting a new airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This AD was prompted by a report that on some airplanes, during the paint removal process for repainting the airplane, the basic corrosion protection (anodizing and primer) coating was sanded down to bare metal on the aluminum skin panels, and the bare metal might not have been treated correctly for corrosion prevention. This AD requires an inspection of structural components of the airplane for any damaged protective coating; inspections of those areas for pitting corrosion, if necessary; a thickness measurement to determine if there is reduced skin thickness, if necessary; and repair, if necessary. We are issuing this AD to detect and correct damaged protective coatings. This condition could result in pitting corrosion damage; and reduced metal thickness, which could result in reduced static and fatigue strength of the airplane's structural parts.
