Department of Transportation January 17, 2007 – Federal Register Recent Federal Regulation Documents

As authorized by Public Law 105-383 and Public Law 107-295, the Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to grant waivers of the U.S.- build requirement of the coastwise laws under certain circumstances. A request for such a waiver has been received by MARAD. The vessel, and a brief description of the proposed service, is listed below. The complete application is given in DOT docket MARAD-2006-26755 at https:// dms.dot.gov. Interested parties may comment on the effect this action may have on U.S. vessel builders or businesses in the U.S. that use U.S.-flag vessels. If MARAD determines, in accordance with Public Law 105-383 and MARAD's regulations at 46 CFR Part 388 (68 FR 23084; April 30, 2003), that the issuance of the waiver will have an unduly adverse effect on a U.S.-vessel builder or a business that uses U.S.-flag vessels in that business, a waiver will not be granted. Comments should refer to the docket number of this notice and the vessel name in order for MARAD to properly consider the comments. Comments should also state the commenter's interest in the waiver application, and address the waiver criteria given in Sec. 388.4 of MARAD's regulations at 46 CFR Part 388.

The FAA proposes to adopt a new airworthiness directive (AD) for General Electric Company (GE) CF34-10E series turbofan engines. This proposed AD would require revising the combustor case published life limit and removing combustor cases from service before reaching a reduced life limit. This proposed AD results from GE's evaluation of the effects to the combustor case due to installing version 5.10 software in the full-authority digital electronic control (FADEC), and revising the combustor case published life limit. We are proposing this AD to prevent uncontained combustor case failure resulting in an in- flight engine shutdown and possible damage to the airplane.

The FAA proposes to supersede an existing airworthiness directive (AD) for Turbomeca Arrius 2 F turboshaft engines. That AD currently requires removing from service certain serial number (SN) fuel control units (FCUs) or replacing the constant delta pressure diaphragm in those FCUs. This proposed AD would require replacing all FCUs not incorporating modification Tf 55 with FCUs that incorporate modification Tf 55. This proposed AD results from the European Aviation Safety Agency (EASA) and Turbomeca expanding the applicability to the full population of FCUs installed on Arrius 2 F turboshaft engines. FCUs not incorporating modification Tf 55 are susceptible to having an improperly assembled constant delta pressure (delta P) diaphragm. We are proposing this AD to prevent an uncommanded engine in-flight shutdown on a single-engine helicopter, resulting in a forced autorotation landing or an accident.

In accordance with the Paperwork Reduction Act of 1995 and its implementing regulations, the Federal Railroad Administration (FRA) hereby announces that it is seeking renewal of the following currently approved information collection activities. Before submitting these information collection requirements for clearance by the Office of Management and Budget (OMB), FRA is soliciting public comment on specific aspects of the activities identified below.

Using data from Management Information System annual reports, FRA has determined that the 2005 rail industry random testing positive rates were 0.73 percent for drugs and 0.17 percent for alcohol. Because the industry-wide random drug testing positive rate has remained below 1.0 percent for the last two years, the Federal Railroad Administrator (Administrator) has determined that the minimum annual random drug testing rate for the period January 1, 2007, through December 31, 2007, will remain at 25 percent of covered railroad employees. In addition, because the industry-wide random alcohol testing violation rate has remained below 0.5 percent for the last two years, the Administrator has determined that the minimum random alcohol testing rate will remain at 10 percent of covered railroad employees for the period January 1, 2007, through December 31, 2007.

Section 9002 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) (Pub. L. 109-59, August 10, 2005) amends chapter 201 of Title 49 of the United States Code by adding section 20154. Section 20154 authorizesbut does not appropriate$350,000,000 per year for each of the fiscal years (FY) 2006 through 2009 for the purpose of funding a grant program to provide financial assistance for local rail line relocation and improvement projects. Section 20154 directs the Secretary of Transportation (Secretary) to issue regulations implementing this grant program, and the Secretary has delegated this responsibility to FRA. This NPRM proposes a regulation intended to carry out that statutory mandate. As of the publication of this NPRM, Congress had not appropriated any funding for the program for FY 2006 or FY 2007.
