Department of Transportation March 14, 2006 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model BD-100-1A10 airplanes. This proposed AD would require an inspection for signs of arcing or heat damage of the electrical connections of the terminal blocks, ground studs, and the end of the wires and surrounding insulation for the windshield and side window anti-ice systems; and repairing any arced or damaged electrical connection. This proposed AD also would require re-torquing electrical connections of the terminal blocks and ground studs for the windshield and side window anti-ice systems. This proposed AD results from an in- service incident involving smoke and odor in the cockpit. We are proposing this AD to prevent loose electrical connections that could arc and overheat, and cause wiring damage of the windshield and side window anti-ice systems. Such wiring damage could result in smoke and/ or fire in the flight compartment.

The FAA proposes to adopt a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) EMB-120() airplane models in operation. This proposed AD would require replacing the protective tubes and conduits of the wiring harnesses of the refueling vent and pilot valves with non-conductive hoses; modifying the harness wiring and supports; and rerouting the harnesses to prevent interference with adjacent strobe light connectors; as applicable. This proposed AD results from a fuel system review conducted by the manufacturer. We are proposing this AD to prevent a potential source of ignition near a fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion.

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 747 airplanes. This proposed AD would require repetitive mid- and low-frequency eddy current inspections for cracks in the overlapped skin panels in the fuselage skin lap joints in sections 41, 42, 44, and 46, and corrective actions if necessary. This proposed AD is prompted by a report indicating that an operator found multiple small cracks in the overlapped skin panels in the fuselage skin lap joints. We are proposing this AD to detect and correct cracks in the overlapped skin panels, which could join together and result in reduced structural capability in the skin and consequent rapid decompression of the airplane.

As authorized by Public Law 105-383 and Public Law 107-295, the Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to grant waivers of the U.S.- build requirement of the coastwise laws under certain circumstances. A request for such a waiver has been received by MARAD. The vessel, and a brief description of the proposed service, is listed below. The complete application is given in DOT docket 2006x-24125 at https:// dms.dot.gov. Interested parties may comment on the effect this action may have on U.S. vessel builders or businesses in the U.S. that use U.S.-flag vessels. If MARAD determines, in accordance with Public Law 105-383 and MARAD's regulations at 46 CFR part 388 (68 FR 23084; April 30, 2003), that the issuance of the waiver will have an unduly adverse effect on a U.S.-vessel builder or a business that uses U.S.-flag vessels in that business, a waiver will not be granted. Comments should refer to the docket number of this notice and the vessel name in order for MARAD to properly consider the comments. Comments should also state the commenter's interest in the waiver application, and address the waiver criteria given in Sec. 388.4 of MARAD's regulations at 46 CFR part 388.

This notice requests public participation in the Office of Management and Budget (OMB) approval process for the renewal of an existing PHMSA information collection.
