Federal Aviation Administration October 23, 2007 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-90-30 airplanes. This proposed AD would require replacement of the wire harness of the auxiliary hydraulic pump with a new wire harness, and routing the new wire harness outside of the tire burst area. This proposed AD results from fuel system reviews conducted by the manufacturer, as well as reports of shorted wires in the right wheel well and evidence of arcing on the power cables of the auxiliary hydraulic pump. We are proposing this AD to prevent shorted wires or electrical arcing at the auxiliary hydraulic pump, which could result in a fire in the wheel well. We are also proposing this AD to reduce the potential of an ignition source adjacent to the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

This action proposes to modify Restricted Area 3404 (R-3404) at Crane, IN. The United States (U.S.) Navy requests that the FAA take action to modify R-3404 for the protection of nonparticipating aircraft from fragments generated during the disposal of a variety of types of ordnance.

On May 18, 2006, the Federal Aviation Administration's Office of Airports (ARP) published a notice in the Federal Register. That Notice told interested parties about the availability of the Preamble for FAA Order 5050.4B, National Environmental Policy Act (NEPA) Implementing Instructions for Airport Actions (71 FR 29014). In that Preamble, ARP stated that it would prepare a desk reference to provide its staff and interested parties with information on integrating and complying with Federal environmental laws, regulations, and Executive Orders other than NEPA (71 FR 29015). Today's Notice alerts interested parties that ARP has prepared the desk reference, entitled ``Environmental Desk Reference for Airport Actions.'' Interested parties may review a copy of the document at the following Web site: https://www.faa.gov/airportsairtraffic/airports/ environmental/environmentaldeskref/. ARP will publish changes to the Desk Reference that may be needed to respond to changes in the laws, regulations, or Executive Orders the Desk Reference discusses.

The FAA is issuing this notice to advise the public of a second meeting of RTCA Special Committee 215, Aeronautical Mobile Satellite (Route) Services, Next Generation Satellite Services and Equipment.
