Department of Transportation January 10, 2011 – Federal Register Recent Federal Regulation Documents

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive inspections for cracking of the fuselage skin of the crown skin panel along the chem- milled step at stringers S-4 left and S-4 right, from stations (STA) 297 through 439, and repair if necessary. This AD also includes terminating action for the repetitive inspections of the repaired areas only. This AD was prompted by reports of cracking in the fuselage skin of the crown skin panel. We are issuing this AD to detect and correct fatigue cracking of the fuselage skin of the crown skin panel, which could result in pressure venting and consequent rapid decompression of the airplane.

FMCSA announces its decision to exempt twenty-one individuals from its rule prohibiting persons with insulin-treated diabetes mellitus (ITDM) from operating commercial motor vehicles (CMVs) in interstate commerce. The exemptions will enable these individuals to operate CMVs in interstate commerce.

FMCSA announces its decision to exempt 15 individuals from the vision requirement in the Federal Motor Carrier Safety Regulations (FMCSRs). The exemptions will enable these individuals to operate commercial motor vehicles (CMVs) in interstate commerce without meeting the prescribed vision standard. The Agency has concluded that granting these exemptions will provide a level of safety that is equivalent to, or greater than, the level of safety maintained without the exemptions for these CMV drivers.

This action proposes to amend Class E airspace at Mosby, MO. Decommissioning of the Mosby non-directional beacon (NDB) at Midwest National Air Center Airport, Mosby, MO, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at Midwest National Air Center Airport.

PHMSA is issuing an Advisory Bulletin to remind operators of gas and hazardous liquid pipeline facilities of their responsibilities, under Federal integrity management (IM) regulations, to perform detailed threat and risk analyses that integrate accurate data and information from their entire pipeline system, especially when calculating Maximum Allowable Operating Pressure (MAOP) or Maximum Operating Pressure (MOP), and to utilize these risk analyses in the identification of appropriate assessment methods, and preventive and mitigative measures.

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 a proposed highway project on US Highway 14 from I-35 in the City of Owatonna, Steele County to Highway 56 near the City of Dodge Center, Dodge County, Minnesota. The proposed improvements include reconstruction and capacity expansion of US 14 as a rural four-lane divided freeway section, including 12.3 miles on a new alignment south of the Dakota, Minnesota, and Eastern Railroad corridor. Those actions grant approvals for the project.

The Federal Transit Administration (FTA) and the Metropolitan Transit Authority of Harris County (METRO) intend to prepare an Environmental Impact Statement (EIS) in accordance with the National Environmental Policy Act (NEPA), to evaluate the proposed transit improvements in the US 90A/Southwest Rail corridor in the Houston metropolitan area (Harris County). The US 90A/Southwest Rail corridor extends approximately eight miles from the vicinity of the Fannin South Station at the southern terminus of the existing METRORail Red Line to West Sam Houston Tollway (Beltway 8) in Missouri City, Texas. The proposed scope of the EIS, including the project's purpose and need, an initial set of alternatives proposed for evaluation, and the significant impacts to be considered, are presented below. A public scoping process seeking comment on the scope of the EIS is announced below.

We are adopting a new airworthiness directive (AD) for the products listed above. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires obtaining written approval from the Manager, Wichita Aircraft Certification Office (ACO), to operate the airplane. This written approval must clearly state that operation is approved per Emergency AD 2010-26-54. This AD was prompted by a Cessna Model LC41-550FG airplane that suffered a significant structural failure in the wing during a production acceptance flight test. We are issuing this AD to prevent catastrophic failure of the wing due to disbonding of the wing skin from the wing spar.

This establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

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:
