Agency Information Collection Activities; Extension of a Currently Approved Information Collection: Transportation of Hazardous Materials, Highway Routing
In accordance with the Paperwork Reduction Act of 1995, FMCSA announces its plan to submit the Information Collection Request (ICR) described below to the Office of Management and Budget (OMB) for review and approval. The FMCSA requests approval to extend an existing information collection entitled ``Transportation of Hazardous Materials, Highway Routing,'' which requires States and Indian tribes to identify designated/restricted routes and restrictions or limitations affecting how motor carriers may transport certain hazardous materials on the highway. On October 30, 2007, FMCSA published a Federal Register notice allowing for a 60-day comment period on the ICR. No comment was received.
Maintenance and Repair Reimbursement Pilot Program
The Maritime Administration is hereby giving notice that the closing date for filing applications to enroll in the Maintenance and Repair Reimbursement Pilot Program is extended until February 15, 2008. The notice announcing the initial application deadline was published in the Federal Register on July 2, 2007 (72 FR 36103). An extension to October 30, 2007 was previously published in the Federal Register on July 30, 2007 (72 FR 41581-01). A subsequent extension to December 30, 2007 was published in the Federal Register on October 30, 2007 (72 FR 61421-01).

Airworthiness Directives; Pratt & Whitney (PW) PW4164, PW4168, and PW4168A Turbofan Engines
The FAA is adopting a new airworthiness directive (AD) for PW PW4164, PW4168, and PW4168A turbofan engines with certain low pressure turbine (LPT) stage 4 disks, part number (P/N) 51N404, installed. This AD requires removing certain LPT stage 4 disks, listed by serial number at the next piece-part exposure or within 7,500 cycles-since-new (CSN). This AD results from a report of improperly manufactured LPT stage 4 disks. We are issuing this AD to prevent an uncontained engine failure due to low-cycle fatigue (LCF), which could result in damage to the airplane.
Special Conditions; Adam Aircraft Industries Model A700; External Fuel Tank Protection During Gear-Up or Emergency Landing
These special conditions are issued for the Adam Aircraft Industries Model A700 airplane. This airplane will have a novel or unusual design feature(s) associated with an External Centerline Fuel Tank (ECFT) that increases the total capacity of fuel by 184 gallons. The tank is located below the fuselage pressure shell immediately below the wing. The Adam A700 ECFT is a novel, unusual and a potentially unsafe design feature that may pose a hazard to the occupants during a gear-up or emergency landing due to fuel leakage and subsequent fire. Traditional aircraft construction places the fuel tanks in a protected area within the wings and/or fuselage. Fuel tanks located in these areas are well above the fuselage skin and are inherently protected by the wing and fuselage structure. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; Robinson Helicopter Company Models R22, R22 Alpha, R22 Beta, R22 Mariner, R44 and R44 II Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Robinson Helicopter Company (Robinson) helicopters. This action requires a one-time visual inspection for skin separation along the leading edge of blade skin aft of the skin-to-spar bond line on the lower surface of each blade and in the tip cap area. This action also requires a ``tap test'' for detecting a separation or void in both bonded areas. This action also requires repainting any exposed area of the blades. If any separation or void is detected, replacing the blade before further flight is required. Thereafter, before each flight, this AD also requires checking for any exposed (bare metal) along the skin-to-spar bond line on the lower surface of each blade near the tip. If any bare metal is found, a mechanic must inspect the area. This amendment is prompted by 11 reports of blade debond, some occurring in flight causing the pilot to feel excessive vibrations and land, and some found during routine maintenance. The actions specified in this AD are intended to detect blade skin debond and to prevent blade failure and subsequent loss of control of the helicopter.
Airworthiness Directives; DG Flugzeugbau GmbH Model DG-500MB 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 an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Environmental Impact Statement; Grays Harbor County, WA
The Federal Highway Administration (FHWA) is issuing this notice to advise the public, affected Indian tribes and agencies that an environmental impact statement (EIS) will be prepared for the proposed development of a site to build pontoons that would be used to restore the function of the existing SR 520 Evergreen Point Bridge in case of catastrophic failure. The Washington State Department of Transportation (WSDOT) is a co-lead agency on the EIS. FHWA and WSDOT will prepare the EIS in accordance with the provisions of the National Environmental Policy Act (NEPA), the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU), and with Washington's State Environmental Policy Act (SEPA).
Airworthiness Directives; Cessna Model 680 Airplanes
We are adopting a new airworthiness directive (AD) for certain Cessna Model 680 airplanes. This AD requires inspecting the routing of the aft fairing wire bundle assembly for adequate separation between the wiring and the hydraulic line; inspecting for chafing or damage of the wire bundle assembly and for damage to the hydraulic line, and doing corrective actions if necessary. This AD results from an incident report which indicated that a hydraulic leak and wire chafing, including signs of heat damage, were found within the lower tail cone fairing area. Similar wire chafing has also been found on other airplanes. We are issuing this AD to detect and correct wire chafing, and inadequate separation of the wiring and hydraulic line, which could lead to electrical arcing and a hydraulic leak and could result in a potential source of ignition and consequent fire.
