June 21, 2006 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation 250-B and 250-C series turboprop and turboshaft engines with certain part numbers (P/Ns) of gas producer rotor assembly tie bolts manufactured by EXTEX Ltd., Pacific Sky Supply Inc., Rolls- Royce Corporation (RRC), and Superior Air Parts Inc. This AD requires operators to remove from service affected gas producer rotor assembly tie bolts, and install serviceable tie bolts. This AD results from eleven reports of RRC tie bolt failure due to high cycle fatigue. We are issuing this AD to prevent tie bolt failure that could cause loss of engine power, resulting in a first stage turbine wheel overspeed and an uncontained engine failure.

The availability of the Draft Comprehensive Conservation Plan and Environmental Assessment (Draft CCP/EA) was announced in the Federal Register on May 30, 2006 (71 FR 30687) for a 30-day public review and comment period ending June 29, 2006. The purpose of this notice is to extend the public review and comment period an additional 15 days.

The U.S. Travel and Tourism Advisory Board (Board) will hold a meeting to discuss topics related to the travel and tourism industry. The Board was established on October 1, 2003, and reconstituted October 1, 2005, to advise the Secretary of Commerce on matters relating to the travel and tourism industry.

The Export-Import Bank, as a part of its continuing effort to reduce paperwork and respondent burden, invites the general public and other Federal Agencies to comment on the proposed information collection, as acquired by the Paperwork Reduction Act of 1995. Our customers will be able to submit this from electronically. The proposed forms may be viewed on our Web site at https://www.exim.gov/pub/ins/ pdf/eib92-31prop.pdf, https://www.exim.gov/pub/ins/pdf/ eib92-32 prop.pdf, https://www.exim.gov/pub/ins/pdf/ eib92-53prop.pdf, and https://www.exim.gov/pub/ins/pdf/ eib99-17prop.pdf.

NMFS proposes regulations to implement Framework Adjustment 43 (Framework 43) to the NE Multispecies Fishery Management Plan (FMP), which was developed by the New England Fishery Management Council (Council). Framework 43 proposes measures to address the incidental catch of NE multispecies by vessels fishing for Atlantic herring. The proposed measures would establish a Herring Exempted Fishery. Vessels issued a Category 1 Atlantic herring fishing permit (Category 1 vessels) would be authorized to possess incidentally caught haddock until the catch of haddock reached the level specified as an incidental haddock catch cap; upon attainment of the haddock catch cap, all herring vessels would be limited to 2,000 lb (907 kg) of herring per trip, if any of the herring on board was caught within the Gulf of Maine/Georges Bank (GOM/GB) Herring Exemption Area defined in Framework 43. Herring Category 1 vessels would also be authorized to possess up to 100 pounds (45 kg) of other regulated multispecies (cod, witch flounder, plaice, yellowtail flounder, pollock, winter flounder, windowpane flounder, redfish, and white hake), and would be required to provide advance notification of their intent to land for purposes of enforcement. Atlantic herring processors and dealers that sort herring catches as part of their operations would be required to cull and report all haddock.

We are adopting a new airworthiness directive (AD) to revise AD 68-17-03, which applies to all Pilatus Aircraft Ltd. (Pilatus) PC-6 series airplanes. AD 68-17-03 requires you to repetitively inspect the rudder end rib for cracks and replace the rudder end rib with a modified rudder end rib when you find cracks. Installing the modified rudder end rib terminates the repetitive inspection requirements of AD 68-17-03. Under a licensing agreement with Pilatus, Fairchild Republic Company (also identified as Fairchild Industries, Fairchild Heli Porter, or Fairchild-Hiller Corporation) produced Model PC-6 series airplanes (manufacturer serial numbers 2001 through 2092) in the United States. AD 68-17-03 was intended to apply to all affected serial numbers of Model PC-6 series airplanes listed on Type Certificate Data Sheet (TCDS) No. 7A15, including the Fairchild-produced airplanes. Consequently, this AD clarifies that all models of the PC-6 airplane on TCDS No. 7A15 (including those models produced under the licensing agreement by Fairchild Republic Company) are included in the applicability. We are issuing this AD to detect and correct cracks in the rudder end rib, which could result in failure of the rudder end rib. This failure could result in loss of rudder control.

We are adopting a new airworthiness directive (AD) that supersedes AD 2005-26-53, which applies to certain Pacific Aerospace Corporation Ltd. (PAC) 750XL airplanes. AD 2005-26-53 currently requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand and the FAA's decision that the actions correct an unsafe condition. Consequently, this AD would require you to remove rivets that have not been fully age hardened and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength affects overall structural capability. This AD retains the actions of the previous AD until the rivets are replaced with the bolts, washers, and nuts. We are issuing this AD so that wing ultimate load requirements are met. If wing ultimate load requirements are not met, wing failure could result with consequent loss of control of the airplane.

This provides notice of the Federal Subsistence Board's in- season management actions to protect Chinook and sockeye salmon escapement in the Copper River, while still providing for a subsistence harvest opportunity, and to protect steelhead in Cable Creek and its tributaries. The revised fishing schedule for the Chitina Subdistrict of the Copper River and the closure of the Cable Creek area provide an exception to the Subsistence Management Regulations for Public Lands in Alaska, published in the Federal Register on March 29, 2006. Those regulations established seasons, harvest limits, methods, and means relating to the taking of fish and shellfish for subsistence uses during the 2006 regulatory year.

This notice announces the availability of EPA's cumulative risk assessment for the chlorinated triazine group of pesticides and opens a public comment period on this document and other support documents. As required by the Food Quality Protection Act (FQPA), a cumulative risk assessment, which evaluates exposures based on a common mechanism of toxicity, was conducted to evaluate the risk from food, drinking water, and non-occupational exposure resulting from all registered uses of chlorinated triazine pesticides. The chlorinated triazine group includes the pesticides atrazine, simazine, and propazine, in addition to their three chlorinated degradates. Propazine, however, was not incorporated into the cumulative risk assessment because no dietary, drinking water, or residential human exposure to propazine is anticipated from any of the currently registered uses. The Agency is concurrently issuing for public comment the Reregistration Eligibility Decision (RED) for simazine and the Tolerance Reassessment Progress and Risk Management Decision (TRED) for propazine. See EPA-HQ-OPP-2005-0151 and EPA-HQ-OPP-2005-0496 in the Notices section of this issue of the Federal Register. A memo finalizing the Interim Reregistration Eligibility Decision for atrazine is being added to docket EPA-HQ-OPP-2003-0367.
