Operations in Class D Airspace
The FAA is removing the provision describing an abbreviated taxi clearance. Previously, air traffic controllers issued abbreviated taxi instructions to aircraft en route to their assigned departure runway, which allowed pilots to cross all runways that intersected the taxi route to their departure runway. The FAA no longer uses these abbreviated taxi clearances and is removing the provision of the regulation that describes this clearance. This action aligns the regulation with current air traffic control practice and responds to the National Transportation Safety Board (NTSB) Safety Recommendation Numbers A-00- 67 and -68.
Amendment of Class E Airspace; Omaha, NE
This action amends Class E airspace at Omaha, NE. Additional controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Eppley Airfield. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport.
Amendment of Class E Airspace; Decatur, IL
This action amends Class E airspace at Decatur, IL. Additional controlled airspace is necessary to accommodate new Area Navigation (RNAV) Standard Instrument Approach Procedures at Decatur Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rule (IFR) operations at the airport. The geographic coordinates of the airport are also adjusted.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
We propose to adopt a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters, which requires inspecting the tail rotor (T/R) pylon for a loose or missing fastener, a crack, damage, or corrosion and adding an internal doubler to the aft shear deck tunnel assembly. This proposed AD is prompted by the discovery of cracks in T/R pylons. The proposed actions are intended to detect a loose or missing fastener, a crack, damage, or corrosion on the T/R pylon and, if present, to repair the T/R Pylon and install a doubler on the aft shear deck tunnel assembly or to replace the T/R pylon and install the doubler on the aft shear deck tunnel assembly to prevent failure of the T/R pylon or other T/R components, and subsequent loss of control of the helicopter.
Amendment of Class E Airspace; Tullahoma, TN
This action amends Class E Airspace in the Tullahoma, TN area, as the Arnold Air Force Base has been closed and controlled airspace associated with the airport is being removed. Airspace reconfiguration is necessary for the continued safety and airspace management of Instrument Flight Rules (IFR) operations within the Tullahoma, TN airspace area. This action also makes a minor adjustment to the geographic coordinates of the Tullahoma Regional Airport/Wm Northern Field.
Amendment of Class D Airspace; Cocoa Beach, FL
This action corrects an error in the legal description of a final rule; technical amendment, published in the Federal Register on April 11, 2012 that amends Class D airspace at Cocoa Beach, FL.
Amendment of Class D and E Airspace; Baltimore, MD
This action amends Class D and E airspace at Martin State Airport, Baltimore, MD. The geographic coordinates of the Baltimore VORTAC are being adjusted to coincide with the FAA's aeronautical database, which show the correct coordinates. This does not affect the boundaries or operating requirements of the airspace.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and -300 series airplanes. This AD was prompted by reports of multiple site damage cracks in the radial web lap and tear strap splices of the aft pressure bulkhead at station (STA) 1582 due to fatigue. This AD requires repetitive inspections for cracking of the aft pressure bulkhead at STA 1582, repair or replacement of any cracked bulkhead, and eventual replacement of the aft pressure bulkhead at STA 1582 with a new bulkhead. Accomplishing the replacement terminates the repetitive inspections required by this AD. We are issuing this AD to prevent fatigue cracking of the aft pressure bulkhead, which could result in rapid decompression of the airplane and possible damage or interference with the airplane control systems that penetrate the bulkhead, and consequent loss of controllability of the airplane.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A319-111, -112, and -132 airplanes; Model A320-111, -211, -212, -214 and -232 airplanes; and Model A321-111, -211, -212, and -231 airplanes. This AD was prompted by reports that corrosion was found on the overwing refueling aperture on the top wing skin, and that for certain airplanes, repairs made using primer coating may prevent proper electrical bonding provision between the overwing refueling cap adaptor and the wing skin. This AD requires performing an electrical bonding test between the gravity fill re-fuel adaptor and the top skin panels on the left-hand and right-hand wings, and if necessary performing a general visual inspection for corrosion of the component interface and adjacent area, and repairing the gravity fuel adaptor if any corrosion is found. We are issuing this AD to detect and correct corrosion and improper bonding, which in combination with a lightning strike in this area, could create a source of ignition in a fuel tank, resulting in a fire or explosion, and consequent loss of the airplane.
