Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series 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) originated 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: * * * * * [B]ogie beam internal paint has been degraded, leading to a loss of cadmium plating and thus allowing development of corrosion pitting. If not corrected, this situation under higher speed could result in the aircraft departing the runway or in the bogie [beam] detaching from the aircraft or [main landing] gear collapses, which would constitute an unsafe condition. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800, -900 and -900ER Series Airplanes
We propose to adopt a new airworthiness directive (AD) for all Boeing Model 737-600, -700, -700C, -800, -900 and -900ER series airplanes. This proposed AD would require repetitive testing of the rudder pedal forces or repetitive detailed inspections of the inner spring of the rudder feel and centering unit, and corrective actions if necessary. This proposed AD also requires replacement of the spring assembly in the rudder feel and centering unit, which terminates the repetitive tests or inspections. This proposed AD results from reports of low rudder pedal forces that were caused by a broken inner spring in the rudder feel and centering unit; a broken inner spring in conjunction with a broken outer spring would significantly reduce rudder pedal forces. We are proposing this AD to prevent reduced rudder pedal forces, which could result in increased potential for pilot- induced oscillations and reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane.
Airworthiness Directives; McDonnell Douglas Model MD-90-30 Airplanes
We propose to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-90-30 airplanes. This proposed AD would require installing fuses and wire protection in certain wing and fuel tank spars. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent possible damage to the fuel level float or pressure switch wires. Such damage could become a potential ignition source inside the fuel tank, and, combined with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Early Scoping Notice for an Alternatives Analysis of Proposed Transit Improvements in Ogden-Weber State University Transit Corridor of Ogden, UT
The Federal Transit Administration (FTA) and the Utah Transit Authority (UTA) issue this early scoping notice to advise other agencies and the public that they intend to explore, in the context of the Council on Environmental Quality's early scoping process, methods of improving transit service in the City of Ogden, Utah. The early scoping process is part of a planning Alternatives Analysis (AA) required by Title 49 United States Code (U.S.C.) Sec. 5309 for the selection of alternatives that will be subject to the appropriate environmental process under the National Environmental Policy Act (NEPA). Early scoping meetings have been planned and are announced below. The Ogden-WSU Transit Corridor Alternatives Analysis is focusing on improving transit service in a 5-mile corridor between downtown Ogden and Weber State University (WSU). The entire study area is located within the City of Ogden, Weber County, Utah. The corridor connects the Ogden Intermodal Center/FrontRunner commuter rail station to the area's major employment, housing, commercial and education destinations, including Downtown Ogden, Weber State University, and McKay Dee Hospital. With the connection to FrontRunner commuter rail, the corridor also serves trips to and from the greater Wasatch Front Region. In 2005, the UTA and its regional partners completed a Major Investment Feasibility Study of the corridor. The 2005 study concluded that a corridor connecting downtown Ogden and WSU was a promising candidate for increased transit capital investment, potentially incorporating streetcar or Bus Rapid Transit service. This study also developed local consensus for an initial statement of the Purpose and Need for the project, and evaluated potential alignments and modes. The planning Alternatives Analysis now being initiated is expected to result in the selection of a Locally Preferred Alternative by the Utah Transit Authority and its partners, which include the Wasatch Front Regional Council, the metropolitan planning organization for the Greater Salt Lake metropolitan area. Other partners include the City of Ogden, Weber County, Weber State University, McKay Dee Hospital, and the Utah Department of Transportation. The Locally Preferred Alternative will then be a ``proposed action,'' subject to an appropriate environmental review under the National Environmental Policy Act (NEPA). If the Preferred Alternative is anticipated to have significant impacts, an environmental impact statement (EIS) would be initiated with a Notice of Intent (NOI) in the Federal Register. Public and agency scoping of the EIS would be conducted at that time. The early scoping notice is intended to generate public comments on the scope of the alternatives analysis. This includes the purpose and need for the project, the range of alternatives, and environmental and community impacts and benefits to be considered in the alternatives analysis.
Airworthiness Directives; Piper Aircraft, Inc. PA-23, PA-31, and PA-42 Series Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Piper Aircraft, Inc. (Piper) PA-23 series airplanes and all PA- 31 and PA-42 series airplanes. This proposed AD would establish life limits for safety-critical nose baggage door components. This proposed AD would also require you to replace those safety-critical nose baggage door components and repetitively inspect and lubricate the nose baggage door latching mechanism and lock assembly. This proposed AD results from several incidents and accidents, including fatal accidents, where the nose baggage door opening in flight was listed as a causal factor. We are proposing this AD to detect and correct worn, corroded, or non- conforming nose baggage door components, which could result in the nose baggage door opening in flight. The door opening in flight could significantly affect the handling and performance of the aircraft. It could also allow baggage to be ejected from the nose baggage compartment and strike the propeller. This failure could lead to loss of control.
Notice of Intent To Rule on Request To Release Airport Property at Baton Rouge Metropolitan Airport, Baton Rouge, LA
The FAA proposes to rule and invites public comment on the release of surplus property land at the Baton Rouge Metropolitan Airport under the provisions of Title 49, U.S.C. Section 47153(c).
Change of Using Agency for Restricted Area 6320; Matagorda, TX
This action changes the using agency of R-6320, Matagorda, TX, from United States Customs Service'' to ``Continental North American Aerospace Defense Command Region (CONR).'' The FAA is taking this action in response to a request from the United States Air Force (USAF), supported by United States Customs and Border Protection (legacy United States Customs Service), to reflect an administrative change of responsibility for the restricted area. There are no changes to the boundaries; designated altitudes; time of designation; or activities conducted within the affected restricted area.
Airworthiness Directives; Airbus Model A330 Airplanes, and Model A340-200 and A340-300 Series Airplanes
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A330, A340-200, and A340- 300 series airplanes. That AD currently requires repetitive inspections of a certain bracket that attaches the flight deck instrument panel to the airplane structure; related investigative and corrective actions if necessary; and replacement of the existing bracket with a titanium- reinforced bracket, which ends the repetitive inspections in the existing AD. This new AD adds requirements only for airplanes on which the existing bracket was replaced with a titanium-reinforced bracket in accordance with the existing AD. The additional requirement is a one- time inspection to determine if certain fasteners are broken or cracked, and corrective actions if necessary. This AD results from a report that incorrect torque values could damage the bracket. We are issuing this AD to prevent a cracked bracket. Failure of this bracket, combined with failure of the horizontal beam, could result in collapse of the left part of the flight deck instrument panel, and consequent reduced controllability of the airplane.
Airworthiness Directives; PILATUS AIRCRAFT LTD. Models PC-12, PC-12/45, PC-12/47, and PC-12/47E Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
