June 2010 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:

NMFS publishes this final rule implementing the Final Amendment 3 to the Consolidated Atlantic Highly Migratory Species (HMS) Fishery Management Plan (FMP). As it developed Amendment 3, NMFS examined a full range of management alternatives available to rebuild blacknose sharks and end overfishing of blacknose and shortfin mako sharks, consistent with recent stock assessments, the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act), and other applicable law, and evaluated options for managing smooth dogfish as a highly migratory species under the HMS FMP. This final rule implements the final conservation and management measures in Amendment 3 for blacknose sharks, shortfin mako sharks, and smooth dogfish. In order to reduce confusion with spiny dogfish regulations, this final rule places both smooth dogfish and Florida smoothhound into the ``smoothhound shark complex.'' This final rule also announces the opening date and 2010 annual quotas for small coastal sharks (SCS). These changes could affect all fishermen, commercial and recreational, who fish for sharks in the Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea.

The FAA is superseding an existing emergency airworthiness directive (AD) 2009-24-52 that was sent previously to all known U.S. owners and operators of TCM 240, 360, 470, 520, and 550 series reciprocating engines. That AD requires before further flight, replacing certain part number (P/N) hydraulic lifters. This AD results from TCM reporting another occurrence of rapid wear on the face of hydraulic lifters, P/Ns 657913, 657915, and 657916, and from the need to expand the applicability of this AD to include the TCM 346 series reciprocating engines and the R-RM IO-240-A reciprocating engines. We are issuing this AD to prevent excessive hydraulic lifter wear, which can result in loss of engine power and loss of control of the airplane.

We are adopting a new airworthiness directive (AD) for certain AVOX Systems and B/E Aerospace oxygen cylinders, as installed on various 14 CFR part 23 or CAR 3 airplanes. This AD requires you to inspect for and remove substandard oxygen cylinders from the airplane. This AD was prompted by the reported rupture of a high-pressure gaseous oxygen cylinder, which had insufficient strength characteristics due to improper heat treatment. We are issuing this AD to prevent an oxygen cylinder from rupturing, which, depending on the location, could result in structural damage and rapid decompression of the airplane, damage to adjacent essential flight equipment, deprivation of the necessary oxygen supply for the flightcrew, and injury to cabin occupants or other support personnel.
