Department of Transportation March 20, 2013 – Federal Register Recent Federal Regulation Documents

As part of its continuing effort to reduce paperwork burdens, and as required by the Paperwork Reduction Act of 1995, 44 U.S.C. 3501- 3519 (PRA), the Surface Transportation Board (Board) gives notice that it is requesting from the Office of Management and Budget (OMB) approval of the information collectionSystem Diagram Mapsfurther described below. The Board previously published a notice about this collection in the Federal Register on January 17, 2013, at 78 FR 3968. That notice allowed for a 60-day public review and comment period. No comments were received. Comments may now be submitted to OMB concerning (1) whether the collection is necessary for the proper performance of the functions of the Board, including whether the collection has practical utility; (2) the accuracy of the Board's burden estimates; (3) ways to enhance the quality, utility, and clarity of the information collected; and (4) ways to minimize the burden of the collection of information on the respondents, including the use of automated collection techniques or other forms of information technology when appropriate. Comments will be summarized and included in the Board's request for OMB approval.

The FHWA is issuing this notice to advise the public that we are rescinding the Notice of Intent (NOI) and Draft Environmental Impact Statement (EIS) for proposed Loop 9 from US 287 to IH 20. A NOI to prepare an EIS for proposed Loop 9 was published in the Federal Register on August 2, 2002 (Volume 67, No. 149, Page 50504), with a subsequent revision to the project limits published in the Federal Register on January 20, 2004 (Vol. 69, No. 12, Page 2809).

This action modifies Class E airspace at Scammon Bay Airport, Scammon Bay, AK. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) standard instrument approach procedures at Scammon Bay Airport. This action enhances the safety and management of aircraft operations at the airport.

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Tay 611-8 turbofan engines. This AD requires inspection and replacement, if necessary, of affected bolts. This AD was prompted by a quality review determination that bolts with reduced material properties may have been installed in some engines. We are issuing this AD to prevent uncontained turbine disc fracture and damage to the airplane.

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) models Tay 620-15 and Tay 650-15 turbofan engines. This AD was prompted by RRD recalculating the Declared Safe Cyclic Life (DSCL) for certain low-pressure compressor (LPC) rotor disc assemblies operating to the Plan D Flight Mission. This AD requires removing the affected LPC rotor disc assemblies at a new lower recalculated DSCL. We are issuing this AD to prevent failure of the LPC rotor disc assembly, uncontained engine failure, and damage to the airplane.

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -300, and -200 Freighter series airplanes; and all Airbus Model A340-200 and -300 series airplanes. This AD was prompted by a determination that the bonding lead from a certain isolation valve to a frame was too close to an electrical harness, which might cause chafing between the electrical harness and the associated bonding lead. This chafing could lead to a short circuit of the isolation valve and consequent non-closure of the isolation valve, which would prevent the air flow to be shut off in case of fire. This AD requires modifying the bonding lead installation of the isolation valve. We are issuing this AD to prevent such chafing, which could result in non-closure of the isolation valve in the event of a fire and consequent damage to the airplane and injury to its occupants.
