Federal Aviation Administration April 24, 2015 – Federal Register Recent Federal Regulation Documents

We propose to supersede Airworthiness Directive (AD) 97-07-14, for certain Airbus Model A320-111, -211, and -231 airplanes. AD 97-07- 14 currently requires modification of an area on the front spar of the wing center section by installing shims and new fasteners to reinforce pressure floor fittings. Since we issued AD 97-07-14, we have determined the need for repetitive inspections on airplanes on which the modification of the rib flange on the front spar of the wing center section has been done. This proposed AD would continue to require modifying the rib flange on the front spar of the wing center section by installing shims and new fasteners to reinforce pressure floor fittings; and would require repetitive high frequency eddy current inspections for cracking of the radius of the rib flanges and vertical stiffener at frame 36, a rototest inspection for cracking of the fastener holes of the rib flanges, repair if needed, and adding additional airplanes to the applicability. We are proposing this AD to prevent fatigue cracking on the rib flange area of the front spar of the wing center section, which can reduce the structural integrity of fuselage frame 36 and the wing center section.

This action establishes Class E Airspace at West Creek, NJ, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving Eagles Nest Airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations within the National Airspace System.

This action establishes Class E airspace at Cando, ND. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Cando Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.

This action amends the legal description of the Baton Rouge, LA, VHF Omnidirectional Range/Tactical Air Navigation aid (VORTAC) located in Class E airspace at Baton Rouge, LA. The Baton Rouge VORTAC and Baton Rouge Metropolitan Airport, Ryan Field, have similar names and both share the same facility identifier but are not co-located. The FAA is renaming the Baton Rouge VORTAC as well as assigning a new facility identifier for the safety and management of aircraft operations within the Baton Rouge, LA, airspace area. This does not affect the boundaries or operating requirements of the airspace.

This action establishes Class E airspace at Cypress, TX. Controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures (SIAPs) at Dry Creek Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPS at the airport.

This action proposes to amend Class E Airspace at Greenville, SC as new Standard Instrument Approach Procedures have been developed at Greenville Downtown Airport. This action would enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also would update the geographic coordinates of the airport.

This action proposes to establish Class E Airspace at Defuniak Springs, FL, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving Defuniak Springs Airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport.

This action amends Class E Airspace at Zephyrhills, FL, as the Zephyrhills Non-Directional Beacon (NDB) has been decommissioned, requiring airspace redesign at Zephyrhills Municipal Airport. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport.
