April 2, 2010 – Federal Register Recent Federal Regulation Documents

The Federal Aviation Administration (FAA) proposes to amend the lightning protection airworthiness standards by establishing new lightning protection regulations for electrical and electronic systems installed on aircraft certificated under parts 23, 27, and 29, and revising lightning protection regulations for electrical and electronic systems installed on airplanes certificated under part 25. The proposed rulemaking would establish two levels of lightning protection for aircraft systems based on consequences of system function failure: Catastrophic consequences which would prevent continued safe flight and landing and hazardous or major consequences which would reduce the capability of the aircraft or the ability of the flightcrew to respond to an adverse operating condition. The proposed rulemaking would also establish lightning protection for aircraft systems according to the aircraft's potential for lightning exposure. Compliance with the new requirements would be based on demonstration of effective lightning protection for electrical and electronic systems. The proposed airworthiness standards would establish consistent lightning protection requirements for electrical and electronic systems.

We (NMFS) announce a 90-day finding on a petition to list the bumphead parrotfish (Bolbometopon muricatum) as threatened or endangered and designate critical habitat under the ESA. We find that the petition presents substantial scientific or commercial information indicating that the petitioned actions may be warranted. Therefore, we initiate a status review of the bumphead parrotfish to determine if listing under the ESA is warranted. To ensure this status review is comprehensive, we solicit scientific and commercial information regarding this species.

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: Surface defects were visually detected on the rudder of one A319 and one A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were a result of de-bonding between the skin and honeycomb core. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane.

The MCAI describes the unsafe condition as: Surface defects were visually detected on the rudder of one Airbus A319 and one A321 in-service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were the result of de-bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300-600 aeroplanes. An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane.

This document supplements the Coast Guard's July 21, 2009 proposal to establish a permanent Special Local Regulation on the navigable waters of Long Island Sound between Port Jefferson, NY and Captain's Cove Seaport, Bridgeport, CT due to the annual Swim Across the Sound event. The proposed amendment is necessary to provide for the safety of life by protecting swimmers and their safety craft from the hazards imposed by marine traffic. This supplemental notice of proposed rulemaking describes an amendment to the list of potential dates and clarifies the limitations placed on marine traffic.

The U.S. Secretary of Education (Secretary) amends the final requirements for the Race to the Top Fund to incorporate and make binding for Phase 2 of the competition State budget guidance.

The Nuclear Regulatory Commission (NRC) is amending its regulations that govern financial protection requirements and indemnity agreements to increase the primary nuclear liability insurance layer from $300 million to $375 million for liability insurance coverage in the event of nuclear incidents at licensed, operating, commercial nuclear power plants with a rated capacity of 100,000 kW or more.

This 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:

This Treasury decision adopts as a final rule, without change, a temporary rule that amended the regulations administered by the Alcohol and Tobacco Tax and Trade Bureau to reflect the repeal of certain special (occupational) taxes effected by section 11125 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users. The regulatory amendments involved the repeal of special taxes on alcohol beverage producers and dealers, tax-free alcohol users, denatured spirits users and dealers, and persons claiming drawback for the manufacture of nonbeverage alcoholic products, and the inclusion of recordkeeping and registration requirements for dealers in distilled spirits, wines, and beer, and for manufacturers of nonbeverage products who claim drawback.

EPA is proposing to approve severable portions of a submittal from the State of Texas, through the Texas Commission on Environmental Quality (TCEQ), on September 25, 2003, to revise the Texas Major and Minor New Source Review (NSR) State Implementation Plan (SIP). Within this SIP submittal, the State repealed a paragraph of the SIP rule pertaining to the Texas Major and Minor NSR SIP and renumbered the SIP rule's paragraphs. We are proposing to approve the new replacement rule as meeting the Major and Minor NSR SIP requirements for voiding of permits.

EPA is proposing a significant new use rule (SNUR) under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified as 1-Propene, 2,3,3,3-tetrafluoro- (CAS No. 754-12-1) which was subject to premanufacture notice (PMN) P-07- 601. This proposed rule would require persons who intend to manufacture, import, or process the substance for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity. The required notification would provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit the activity before it occurs.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Model 747-200C and -200F series airplanes. That AD currently requires repetitive inspections to find fatigue cracking in the floor panel attachment fastener holes of the upper chord of certain upper deck floor beams in Section 41 (i.e., body station 520 and forward), and repair if necessary. The existing AD also provides optional modifications, which extend the threshold for initiating certain repetitive inspections. This new AD requires additional repetitive inspections to find fatigue cracking in the floor panel attachment fastener holes of the upper chord of certain other upper deck floor beams in Section 41 and Section 42 (i.e., aft of body station 520); repetitive inspections to find fatigue cracking in the permanent fastener holes of the upper chord of certain upper deck floor beams in Section 41; and related investigative and corrective actions. This new AD also provides a new optional modification, which terminates certain repetitive inspections. This AD results from new reports of cracking in the upper chord of the upper deck floor beams in Sections 41 and 42, and new analysis that shows the permanent fastener holes of the upper chord of certain upper deck floor beams in Section 41 are also susceptible to fatigue cracking. We are issuing this AD to detect and correct cracking in the upper chord of the upper deck floor beams. Such cracking could extend and sever the floor beams, which could result in rapid decompression and loss of controllability of the airplane.
