Department of Transportation June 22, 2011 – Federal Register Recent Federal Regulation Documents

This notice announces actions taken by the FHWA and other Federal agencies that are final within the meaning of 23 U.S.C. 139(l)(1). The actions relate to the proposed Illinois Route 336 (IL 336) highway project, for construction of an access-controlled, four- lane expressway on new right-of-way between the proposed Macomb Bypass in McDonough County, passing through Fulton County to Interstate 474 (I-474) on the west side of Peoria in Peoria County, Illinois. Those actions grant licenses, permits and approvals for the project.

This document requests comments on data about passenger motor vehicle thefts that occurred in calendar year (CY) 2009 including theft rates for existing passenger motor vehicle lines manufactured in model year (MY) 2009. The preliminary theft data indicate that the vehicle theft rate for CY/MY 2009 vehicles (1.33 thefts per thousand vehicles) decreased by 21.3 percent from the theft rate for CY/MY 2008 vehicles (1.69 thefts per thousand vehicles). Publication of these data fulfills NHTSA's statutory obligation to periodically obtain accurate and timely theft data, and publish the information for review and comment.

This notice proposes updated regulations to enhance the integration of value engineering (VE) analysis in the planning and development of highway improvement projects. The intent of these actions is to bring the FHWA's VE regulations up-to-date and consistent with prior changes in legislation and regulations.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD would require inspecting to determine whether a third Halon fire extinguisher bottle is installed in the auxiliary power unit (APU) fragment impact zone, revising the limitations section of the airplane flight manual to add restrictions for APU usage for certain airplanes having a third fire extinguisher bottle, and removing the third fire extinguisher bottle from certain airplanes. This proposed AD was prompted by notification from the airplane manufacturer that the third fire extinguisher bottle is mounted in a small-fragment impact zone. We are proposing this AD to prevent penetration of the bottle by fragments released due to a failure of the APU rotor system. The bottle could rupture and cause substantial damage to primary airframe structure and primary flight controls.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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: * * * * * A recent analysis conducted by the manufacturer showed a particular risk for explosive failure of the * * * hydraulic accumulator. This condition, if not detected and corrected, might, for some aeroplane installations, lead to damage to all three hydraulic circuits, possibly resulting in loss of control of the aeroplane or could, for certain other aeroplane installations, lead to an undetected fire in the wheel bay. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

We are superseding an existing airworthiness directive (AD) that applies to the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
