Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R Series Airplanes and Model C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300-600 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
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 This final rule makes some nomenclature changes, removes outdated references, and provides clarification on the meaning of roads ``open to public travel'' and ``substantial conformance.''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
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 (SAFETEA-LU) (Pub. L. 109-59). 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.
Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH Model Duo Discus T Gliders
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 Alaskan High Altitude Reporting Points; AK
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; Rolls-Royce Corporation AE 2100D3 Turboprop Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce 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 low-cycle-fatigue 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.
Establishment of Class D Airspace; Castle Airport, Atwater, CA
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.
Anthropomorphic Test Devices; SID-IIs Side Impact Crash Test Dummy 5th Percentile Adult Female
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 SID-IIs Build Level D (``SID-IIs'') test dummy. The SID-IIs 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 small-stature occupants in side impacts. NHTSA plans to use the SID-IIs dummy in an upgraded Federal motor vehicle safety standard on side impact protection.
Anthropomorphic Test Devices; ES-2re Side Impact Crash Test Dummy 50th Percentile Adult Male
This final rule amends the agency's regulation on anthropomorphic test devices to add specifications and qualification requirements for a new mid-size adult male crash test dummy, called the ``ES-2re'' test dummy. The ES-2re 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 ES-2re dummy in an upgraded Federal Motor Vehicle Safety Standard on side impact protection.
