April 21, 2010 – Federal Register Recent Federal Regulation Documents

The Coast Guard is establishing a temporary security zone in certain waters of Washington Channel on the Potomac River. The security zone is necessary to provide for the security and safety of life and property of event participants, spectators and mariners during the U.S. Coast Guard Commandant's Change of Command ceremony from 6 a.m. through 5 p.m. on May 25, 2010. Entry into this zone is prohibited unless authorized by the Captain of the Port, Baltimore, Maryland, or his designated representative.

NMFS announces the reduction of the scup coastwide commercial possession limit from Maine through North Carolina for the Winter I period. Regulations governing the scup fishery require publication of this notification to advise the coastal states from Maine through North Carolina that 80 percent of the commercial quota allocated to the Winter I period is projected to be harvested and to announce that the possession limit for a Federal vessel permit holder is reduced.

The Commander, First Coast Guard District, has issued a temporary deviation from the regulation governing the operation of the SR1A Bridge across the Hampton River at mile 0.0, at Hampton, New Hampshire. This temporary deviation allows the SR1A Bridge to remain in the closed position for 10 hours on one day to facilitate bridge maintenance.

The Coast Guard proposes to establish a safety zone, on the navigable waters of the lower Colorado River, Laughlin, NV, in support of a fireworks display near the AVI Resort and Casino. This safety zone is necessary to provide for the safety of the participants, crew, spectators, participating vessels, and other vessels and users of the waterway. Persons and vessels would be prohibited from entering into, transiting through, or anchoring within this safety zone unless authorized by the Captain of the Port, or his designated representative.

We propose to adopt a new airworthiness directive (AD) for certain Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747- 200F, 747-300, 747-400, 747SR, and 747SP series airplanes. This proposed AD would require repetitive detailed inspections of certain overwing intercostal webs, and related investigative and corrective actions if necessary. This proposed AD results from reports of cracks in overwing intercostal webs. We are proposing this AD to detect and correct such cracking, which could grow and result in a severed intercostal. If an intercostal is severed, cracks could develop in the adjacent frame structure and skin, resulting in a rapid loss of cabin pressure.

We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:
