Federal Aviation Administration December 5, 2005 – Federal Register Recent Federal Regulation Documents

This document makes a correction to the notice published in the Federal Register announcing an opening on the National Parks Overflight Advisory Group Aviation Rulemaking Committee representing Indian Tribal interests. In that notice, there was no closing date included for nominations. This notice corrects that oversight. Effective Date: This correction is effective on December 5, 2005.

The Federal Aviation Administration (FAA) is issuing this Notice of Availability to advise the public that a Draft Supplemental Environmental Assessment (DSEA) will be available for public review beginning November 22, 2005. The DSEA details the proposed modification to the Four Corner-Post Plan at Las Vegas McCarran International Airport and addresses the potential environmental impacts associated with its implementation. The DSEA presents the Purpose and Need for the proposed project, a comprehensive analysis of the alternatives to the proposed project, and studies the potential environmental impacts associated with the proposed modification to the Four Corner-Post Plan. The Federal Aviation Administration (FAA) proposes to modify an existing departure procedure that was implemented as part of the Four Corner-Post Plan at McCarran International Airport (LAS), Las Vegas, Nevada, in October 2001. The Four Corner-Post Plan was developed and implemented to address growing airspace and air traffic control inefficiencies caused by increases in air traffic in the Las Vegas TRACON airspace. This Draft Supplemental Environmental Assessment (SEA) has been developed to assess the potential environmental impacts that may be associated with the proposed modification of the STAAV Area Navigation (RNAV) Standard Instrument Departure (SID) to accommodate eastbound departures from Runway 25. Public Comment Period and Public Workshops: The public comment period on the DSEA will start November 22, 2005 and will end on December 30, 2005. Public Workshops will be held on December 12, 2005 from 6-9 p.m. at Sierra Vista High School, 8100 W. Robindale Road, Las Vegas, NV and on December 13, 2005 from 6-9 p.m. at Centennial High School, 10200 Centennial Parkway, Las Vegas, NV. The public will be afforded the opportunity to present oral testimony and/or written testimony pertinent to the subject of the workshops. Forms for providing written comments will be available and a court reporter will be available to record oral comments at the Public Workshops. All written comments are to be submitted to Ms. Sara Hassert, Landrum & Brown, Inc., 8755 W. Higgins Rd., Ste. 850, Chicago, IL 60631, fax: 773-638-2901, e-mail: shassert@landrum-brown.com and the comments must be postmarked and email/fax must be sent by no later than midnight, December 30, 2005.

This final rule will revise the Class E airspace area at Wenatchee, WA. Additional Class E airspace is necessary to accommodate aircraft using a new Instrument Landing System (ILS) Standard Instrument Approach Procedure (SIAP) at Wenatchee/Pangborn Memorial Memorial Airport. This change is necessary for the safety of Instrument Flight Rules (IFR) aircraft executing the new SIAP at Wenatchee/ Pangborn Memorial Airport, Wenatchee, WA.

The FAA is requesting public comment on the Pease Development Authority's request to sell a portion (11.57 acres) of Airport property from aeronautical use to non-aeronautical use. The property is located at 40 Oak Avenue, Portsmouth, New Hampshire and is currently used for revenue production. Upon disposition the property will be used for construction of a Federal building by the General Services Administration. The property was acquired under the Surplus Property Act under a Deed from the United States Air Force dated January 28, 2004. The disposition of proceeds from the disposal of airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999.

This document proposes superseding an existing airworthiness directive (AD) that currently applies to Eurocopter France (ECF) Model SA 365N, N1, and AS 365N2 helicopters. That AD currently requires inspecting the main gearbox (MGB) suspension diagonal cross-member (diagonal cross-member) for cracks and replacing it with an airworthy part if any crack is found. This action proposes to require more frequent inspections of the diagonal cross-member and adding the Model SA-366G1 helicopters to the applicability. This proposal is prompted by several reports of cracks in the diagonal cross-member. The actions specified by the proposed AD are intended to prevent failure of the diagonal cross-member, pivoting of the MGB, severe vibrations, and a subsequent forced landing.

The FAA is superseding an existing airworthiness directive (AD), which applies to all Aerospatiale Model ATR42-200, ATR42-300, and ATR42-320 airplanes. That AD currently requires inspections to determine the proper installation of rivets in certain key holes and to detect cracks in the area of the key holes where rivets are missing; and correction of discrepancies. The existing AD also requires various inspections of the subject area for discrepancies, and corrective actions if necessary; and replacement of certain cargo door hinges with new hinges. For certain airplanes, the existing AD also requires replacement of friction plates, stop fittings, and bolts with new parts. This new AD requires additional corrective actions for certain airplanes. This AD results from discovery of cracks around key holes on certain fuselage frames where rivets were missing. We are issuing this AD to prevent fatigue cracks of the cargo door skin, certain frames, and entry door stop fittings and friction plates, which could result in reduced structural integrity of the airplane.

The FAA is superseding an existing airworthiness directive (AD) that applies to certain EMBRAER Model EMB-135 and Model EMB-145 series airplanes. The existing AD currently requires repetitive inspections of the spring cartridges of the elevator gust lock system to determine if the lock washer projection correctly fits the slots in the cartridge flange, and corrective action if necessary. The existing AD also provides for optional terminating action for the repetitive inspections for certain airplanes. This AD retains the requirements of the existing AD and adds a requirement for final terminating action for all affected airplanes. This AD results from reports of an improperly fitting lock washer causing the clevis of the spring cartridge in the electromechanical elevator gust lock system to become unscrewed. We are issuing this AD to prevent the unscrewing of the spring cartridge clevis from jamming the elevator, which could lead to reduced controllability of the airplane.

The FAA is adopting a new airworthiness directive (AD) for certain Learjet Model 45 airplanes. This AD requires modifying the electrical wire bundle for the alternator on the left-hand engine, inspecting for clearance between wire harnesses and engine tubing for each engine, and corrective actions if necessary. For certain airplanes, this AD also requires replacing the fuses for the hydraulic shutoff valves with fuses having higher amperage. This AD results from a report of a fire in the left-hand engine nacelle. We are issuing this AD to prevent chafing between the wire bundle for the alternator on each engine and the hydraulic lines, which could result in a fire in the engine nacelle.
