Change to Time of Designation of Restricted Area 6320; Matagorda, TX
This action amends the time of designation for Restricted Area 6320 (R-6320), Matagorda, TX. Specifically, this action amends the time of designation from ``Continuous'' to ``Intermittent by [Notice to Airmen] NOTAM.'' This rule makes no other changes to R-6320. The FAA is issuing this amendment because R-6320 is no longer continuously needed for the aerostat balloon, used in support of U.S. National Security interests.
Use of Certain Portable Oxygen Concentrator Devices Onboard Aircraft
The Federal Aviation Administration (FAA) is making minor technical changes to a final rule published in the Federal Register on July 12, 2005 (70 FR 40156). That final rule created Special Federal Aviation Regulation 106 (SFAR 106). In that final rule the FAA inadvertently failed to make conforming amendments to additionally apply the SFAR to parts 125 and 135 as proposed, and to include references in those parts to the existence of SFAR 106 published in part 121.
Fire Penetration Resistance of Thermal/Acoustic Insulation Installed on Transport Category Airplanes
The FAA extends, by 24 months, the date for operators to comply with the fire penetration resistance requirements of thermal/ acoustic insulation used in transport category airplanes manufactured after September 2, 2007. This extension is from September 2, 2007, to September 2, 2009. This action is necessary to allow airframe manufacturers enough time, after getting an acceptable certification test facility, to select and certificate appropriate installations.
Change to Controlling Agency of Restricted Area 2312; Fort Hauchuca, AZ
This action amends the controlling agency for Restricted Area 2312 (R-2312), Fort Hauchuca, AZ. Specifically, this action amends the controlling agency from ``Libby [Army Air Field] AAF [Airport Traffic Control Tower] ATCT'' to ``Albuquerque [Air Route Traffic Control Center] ARTCC.'' This is an administrative change that does not alter the boundaries, designated altitudes, time of designation, or activities conducted within R-2312. The FAA is taking this action at the request of the United States (U.S.) Army and the U.S. Air Force because Libby AAF ATCT is not a 24-hour facility and R-2312 is not fully contained within the airspace delegated to Libby AAF ATCT by Albuquerque ARTCC.
Modification of VOR Federal Airway V-2; East Central United States
This action modifies VOR Federal Airway V-2 over the East Central United States to support modified arrival and departure procedures to the Detroit Metropolitan Wayne County Airport (DTW), Detroit, Michigan. These procedures were modified in conjunction with the Midwest AirSpace Enhancement (MASE) project. The FAA is taking this action to enhance safety and to improve the efficient use of the navigable airspace assigned to the Chicago and Cleveland Air Route Traffic Control Centers (ARTCC).
Airworthiness Directives; Airbus Model A318, A319, A320, and A321 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A318-100, A319-100, A320-200, A321-100, and A321-200 series airplanes; and Model A320-111 airplanes. The existing AD currently requires modification of the electrical bonding of all structures and systems installed inside the center fuel tank. That AD results from fuel system reviews conducted by the manufacturer. This proposed AD would require modification of additional bonding points inside the center fuel tank. This proposed AD results from a report that additional bonding points need to be modified in order to prevent electrical arcing in the center fuel tank. We are proposing this AD to prevent electrical arcing in the center fuel tank due to inadequate bonding, which could result in an explosion of the center fuel tank and consequent loss of the airplane.
Airworthiness Directives; Airbus Model A330 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued 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 an incomplete discharge of the extinguishing agent in the fire zone, which could lead, in the worst case, in combination with an engine fire, to a temporary uncontrolled engine fire. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes
The FAA is superseding an existing airworthiness directive (AD), that applies to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That AD currently requires repetitive inspections for cracks, sealant damage, and corrosion of the main fittings of the main landing gear (MLG), and corrective actions if necessary. This new AD reduces the compliance times for inspecting certain low-utilization airplanes, and provides a terminating action for the repetitive inspections. This AD results from a report of a cracked main fitting of the MLG. We are issuing this AD to detect and correct fatigue cracking of the main fitting of the MLG and consequent failure of the main fitting, which could result in the collapse of the MLG.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP Series Airplanes Equipped with General Electric CF6-45 or -50 Series Engines, or Equipped with Pratt & Whitney JT9D-3 or -7 (Excluding -70) Series Engines
The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. The existing AD currently requires repetitive inspections to detect cracks and fractures of the strut front spar chord assembly at each strut location, and repair if necessary. This new AD expands the inspection area by requiring repetitive inspections for any cracks or fracture of the strut front spar chord assembly in an area forward of the existing inspection area at each strut location, and repair if necessary. This AD results from a strut front spar chord assembly that was found fractured, forward of the inspection area required by the existing AD. We are issuing this AD to detect and correct cracks and fracture of the nacelle strut front spar chord assembly. Fracture of the front spar chord assembly could lead to loss of the strut upper link load path and consequent fracture of the diagonal brace, which could result in in-flight separation of the strut and engine from the airplane.
Ninth Meeting: RTCA Special Committee 203/Minimum Performance Standards for Unmanned Aircraft Systems and Unmanned Aircraft
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 203, Minimum Performance Standards for Unmanned Aircraft Systems and Unmanned Aircraft.
Public Notice of Waiver of Aeronautical Land-Use Assurance-Hallock Municipal Airport, Hallock, MN
The Federal Aviation Administration (FAA) is considering a proposal to change a portion of the airport from aeronautical use to non-aeronautical use and to authorize the sale and/or conversion of the airport property. The proposal consists of two parcels of land containing a total of 4.18 acres located on the north side of the airport along County Road 13. There are no impacts to the airport by allowing the airport to dispose of the property. These parcels were originally acquired under Grant No. FAAP-01 in 1964. The parcels were acquired for a runway that has since been abandoned and replaced by a new primary runway in a different location. The land comprising these parcels is, therefore, no longer needed for aeronautical purposes and the airport owner wishes to sell at 4.0 acre parcel for an agricultural implement dealership and convert 0.18 acres of another parcel for use as a city wastewater lift station site. The income from the sale/conversion of these parcels will be reinvested in the airport for extending the useful life of the runway pavement. Approval does not consistute a commitment by the FAA to financially assist in the disposal of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the disposal of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.
