Airworthiness Directives; Rolls-Royce Corporation AE 2100D3 Turboprop Engines

Thu, Dec 14 2006 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for RollsRoyce Corporation (RRC) AE 2100D3 turboprop engines. This AD requires removing certain part number (P/N) compressor cone shaft assemblies at a new reduced cyclic life limit of 5,000 engine cycles. This AD results from lowcyclefatigue testing and analysis of certain P/N compressor cone shaft assemblies, by RRC. We are issuing this AD to prevent uncontained failure of the compressor cone shaft assembly, leading to engine shutdown and damage to the airplane.

Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH Model Duo Discus T Gliders

Thu, Dec 14 2006 11:00:00 GMT

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the possible failure of the attachment of the propeller blades. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Establishment of Class D Airspace; Castle Airport, Atwater, CA

Thu, Dec 14 2006 11:00:00 GMT

This action establishes Class D airspace at Castle Airport, Atwater, CA. A contract Airport Traffic Control Tower (ATCT) is being established at Castle Airport, Atwater, CA, which will meet criteria for Class D airspace. Class D airspace is required when the ATCT is open, and to contain and protect Standard Instrument Approach Procedures (SIAPs) and other Instrument Flight Rules (IFR) operations at the airport. This action would establish Class D airspace extending upward from the surface to 2,500 feet Mean Sea Level (MSL) within a 4.5 nautical mile radius of the airport.

Establishment of Alaskan High Altitude Reporting Points; AK

Thu, Dec 14 2006 11:00:00 GMT

This action establishes four high altitude reporting points AYZOL, BORAN, EMSOW, and TIBOY in Alaska. The designation of these high altitude reporting points is needed to facilitate the separation of air traffic in Alaska.

Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes and Model C4-605R Variant F

Thu, Dec 14 2006 11:00:00 GMT

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300600 series airplanes. This proposed AD would require revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors caused by latent failures, alterations, repairs, or maintenance actions, could result in fuel tank explosions and consequent loss of the airplane.

Traffic Control Devices on Federal-Aid and Other Streets and Highways; Standards

Thu, Dec 14 2006 11:00:00 GMT

The FHWA is revising its regulation that prescribes procedures for obtaining basic uniformity of traffic control devices on Federal aid and other streets and highways. This final rule makes some nomenclature changes, removes outdated references, and provides clarification on the meaning of roads ``open to public travel'' and ``substantial conformance.''

National Safe Routes to School Task Force to the Secretary of Transportation

Thu, Dec 14 2006 11:00:00 GMT

This document announces the first meeting of the National Safe Routes to School Task Force to the Secretary of Transportation. This is the first meeting of the task force. The purpose of the Task Force is to advise the Secretary of Transportation, through the Federal Highway Administration (FHWA) Office of Safety, on strategies to advance Safe Routes to School (SRTS) Programs nationwide and to encourage children, including those with disabilities, to walk and bicycle to school pursuant to Section 1404(h) of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEALU) (Pub. L. 10959). This meeting is open to the public and will have time allocated for public testimony. The public is welcome to present written or oral comments to the Task Force.

Docket No. NHTSA-2004-25441

Thu, Dec 14 2006 11:00:00 GMT

This final rule amends the agency's regulation on anthropomorphic test devices to add specifications and qualification requirements for a new midsize adult male crash test dummy, called the ``ES2re'' test dummy. The ES2re dummy has enhanced injury assessment capabilities compared to devices existing today, which allows for a fuller assessment of the types and magnitudes of the injuries occurring in side impacts and of the efficacy of countermeasures in improving occupant protection. The agency plans to use the ES2re dummy in an upgraded Federal Motor Vehicle Safety Standard on side impact protection.

Docket No. NHTSA 25442 RIN 2127-AJ16

Thu, Dec 14 2006 11:00:00 GMT

This final rule amends the agency's regulation on anthropomorphic test devices to add specifications and qualification requirements for the 5th percentile adult female crash test dummy, called the SIDIIs Build Level D (``SIDIIs'') test dummy. The SIDIIs dummy is instrumented in the head, thorax, abdomen and pelvis, which enables it to assess in a comprehensive manner the performance of vehicles in protecting smallstature occupants in side impacts. NHTSA plans to use the SIDIIs dummy in an upgraded Federal motor vehicle safety standard on side impact protection.

Nevada Pacific Railroad Corporation--Lease and Operation Exemption--Rail Lines of Pan Western Corporation

Thu, Dec 14 2006 11:00:00 GMT

Nevada Pacific Railroad Corporation (NPRC),\1\ a noncarrier, has filed a verified notice of exemption under 49 CFR 1150.31 to lease from Pan Western Corporation (Pan Western) and operate approximately 2.66 miles of private rail line owned by Pan Western, extending between milepost 0.0, and milepost 2.66, in Clark County, NV.\2\ Pan Western intends to lease the railroad line to NPRC so that NPRC may initiate and provide common carrier rail operations on and over the line. \1\ The verified notice of exemption was originally filed under the name UP Nevada Railroad LLC.
