Proposed Amendment of Class E Airspace; Woodland, CA
This action proposes to amend Class E airspace at Watts- Woodland Airport, Woodland, CA. The proposed decommissioning of the Travis VHF Omni-Directional Radio Range (VOR) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Proposed Amendment of Class E Airspace; Fairfield, CA
This action proposes to amend Class E airspace at Travis Air Force Base (AFB), Fairfield, CA. The proposed decommissioning of the Travis VHF Omni-Directional Radio Range (VOR) has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; Agusta S.p.A. Helicopters
We are publishing a new airworthiness directive (AD) for certain Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters that requires establishing a revised life limit for each tail rotor (T/R) blade and updating the helicopter's historical records, repetitively inspecting T/R blades for a crack, and replacing certain T/R blades. This AD is prompted by a fatal accident involving an Agusta Model AW139 helicopter, which may have been caused by cracks in a T/R blade. These actions are intended to detect and prevent a crack in a T/R blade, which could lead to failure of a T/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC- 10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require adding design features to detect electrical faults, to detect a pump running in an empty fuel tank, and to ensure that a fuel pump's operation is not affected by certain conditions. We are proposing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to revise an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes; all Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes; all Model CL-600-2D15 (Regional Jet Series 705) airplanes; and all Model CL-600-2D24 (Regional Jet Series 900) airplanes. The existing AD currently requires replacing certain water accumulator assemblies having a certain part installed on the pitot and static lines of the air data computer (ADC). Since we issued that AD, an error was discovered in one service document number, and we have determined that credit for accomplishing actions in another erroneously cited service document should be removed from that AD. This proposed AD would correct the erroneous service document number and remove the other erroneously cited service document from that AD. We are proposing this AD to prevent pitot-static tubing from becoming partially or completely blocked by water, which could result in erroneous airspeed and altitude indications and consequent loss of control of the airplane.
Modification of VOR Federal Airways V-135 and V-137; Southwest United States
This action modifies VHF omnidirectional range (VOR) Federal airways V-135 and V-137 by extending the airways to the Mexicali, Mexico VOR/DME. This action enhances navigation and air traffic control coordination for aircraft proceeding across the United StatesMexican border.
Modification, Revocation and Establishment of Air Traffic Service Routes; Windsor Locks Area; CT
This action corrects a final rule published in the Federal Register on April 5, 2012, that amends the airway structure in the vicinity of Windsor Locks, CT, due to the planned decommissioning of the Bradley VHF omnirange/tactical air navigation aid. This action corrects the longitude coordinate for one point in the description of area navigation (RNAV) route T-300.
