Department of Transportation 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.

Consistent with the Paperwork Reduction Act of 1995 and its implementing regulations, this document provides notice of FRA's intent to modify the existing instructions applicable to one currently approved information collection reporting form (Form FRA F 6180.54, Rail Equipment Accident/Incident Report). For a projected five-year period, FRA seeks to gather additional data on Form FRA F 6180.54 concerning rail cars carrying petroleum crude oil (crude oil) in any train involved in an FRA reportable accident. At present, railroads do not report this specific information to FRA on Form FRA F 6180.54, but rather aggregate crude oil information with information about all other hazardous materials being transported. This new reporting requirement will help FRA capture more specific information on accidents that involve trains transporting crude oil and provide FRA an opportunity to better address risks to railroad safety and the general public.

This action proposes to amend Class E Airspace at Campbellsville, KY as the Taylor County NDB has been decommissioned, requiring airspace redesign at Taylor County Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

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

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

This action establishes Class E airspace at Edgeley, ND. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Edgeley 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 Class E Airspace at Manchester, NH, as a new approach procedure has been developed, requiring airspace redesign at Manchester Airport. This enhances the safety and management of instrument flight rules (IFR) operations at the airport. This action also updates the geographic coordinates of the airport.

This action establishes Class E airspace at Sonora, TX. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at JL Bar Ranch 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 establish Class E airspace at Highmore, SD. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Highmore 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.

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a report of a rupture of a main landing gear (MLG) sliding tube axle. This proposed AD would require an inspection to identify the part number and serial number of the MLG sliding tubes installed on the airplane; and an inspection of the axle on certain MLG sliding tubes for burned areas, and replacement of the sliding tube if necessary. We are proposing this AD to detect and correct cracks in the axle and (partial) detachment of the axle and wheel from the sliding tube, which could result in failure of an MLG.
