Agency Information Collection Activities: Request for Comments for New Information Collection
The FHWA has forwarded the information collection request described in this notice to the Office of Management and Budget (OMB) for approval of a new information collection. We published a Federal Register Notice with a 60-day public comment period on this information collection on November 3rd, 2006. We are required to publish this notice in the Federal Register by the Paperwork Reduction Act of 1995.
Seaway Regulations and Rules: Periodic Update, Various Categories
The Saint Lawrence Seaway Development Corporation (SLSDC) and the St. Lawrence Seaway Management Corporation (SLSMC) of Canada, under international agreement, jointly publish and presently administer the St. Lawrence Seaway Regulations and Rules (Practices and Procedures in Canada) in their respective jurisdictions. Under agreement with the SLSMC, the SLSDC is amending the joint regulations by updating the Seaway Regulations and Rules in various categories. The changes update the following sections of the Regulation and Rules: Condition of Vessels; Preclearance and Security for Tolls; Seaway Navigation; Dangerous Cargo; and, General. These amendments are necessary to take account of updated procedures and will enhance the safety of transits through the Seaway. Several of the amendments are merely editorial or for clarification of existing requirements.
Airworthiness Directives; SOCATA-Groupe Aerospatiale TB 20 and TB 21 Airplanes
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 reports of interference between the wing spar lower boom and the wheel fairing attaching screw. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Dart 528, 529, 532, 535, 542, and 555 Series Turboprop Engines
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd & Co KG (RRD) Dart 528, 529, 532, 535, 542, and 555 series turboprop engines. This AD requires a dimensional inspection of the intermediate pressure turbine (IPT) disk or an ultrasonic inspection of the seal arm contact between the high pressure turbine (HPT) and the IPT disk seal arm and rework or replacement of the IPT disk if wear outside acceptable limits is found. This AD results from reports of a number of HPT disk failures, some of which resulted in portions of the HPT disk being released. We are issuing this AD to prevent HPT disk failure, which can result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; EADS SOCATA TBM 700 Airplanes
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 a report of a master cylinder yoke failure. We are issuing this AD to require actions to correct the unsafe condition on these products.
Airworthiness Directives; Rolls-Royce plc RB211 Trent 700 Series Turbofan Engines
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce plc (RR) RB211 Trent 700 series turbofan engines. That AD currently requires initial and repetitive borescope inspections of the high pressure-and-intermediate pressure (HP-IP) turbine internal and external oil vent tubes for coking and carbon buildup, and cleaning or replacing the vent tubes if necessary. This AD requires the same actions but uses more stringent tube replacement criteria than the previous AD. This AD results from a recent incident where an RB211 Trent 700 series turbofan engine had an oil vent tube rupture as a result of blockage, leading to significant loss of engine oil. The incident indicates that further measures are necessary to control carbon buildup in the oil vent tubes. We are issuing this AD to prevent internal oil fires due to coking and carbon buildup, that could cause uncontained engine failure and damage to the airplane.
Pipeline Safety: Meeting of the Technical Hazardous Liquid Standards Committee
This notice announces a public meeting of PHMSA's Technical Hazardous Liquid Pipeline Safety Standards Committee (THLPSSC) to vote on a proposed rule to extend pipeline safety regulation to rural onshore hazardous liquid gathering lines and low stress lines. This proposed rule partially addresses a statutory requirement of the Pipeline Inspection, Protection, Enforcement, and Safety Act of 2006 (PIPES Act of 2006).
Noise Exposure Map Notice; Receipt of Noise Compatibility Program and Request for Review, Shreveport Regional Airport, Shreveport, LA
The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by Shreveport Airport Authority for the Shreveport Regional Airport under the provisions of 49 U.S.C. 47501 et seq. (Aviation Safety and Noise Abatement Act) and 14 CFR part 150 are in compliance with applicable requirements. The FAA also announces that it is reviewing a proposed noise compatibility program that was submitted for the Shreveport Regional Airport under part 150 in conjunction with the noise exposure map, and that this program will be approved or disapproved on or before July 11, 2007.
Pipeline and Hazardous Materials Safety Administration Office of Hazardous Materials Safety; Notice of Applications for Modification of Special Permit
In accordance with the procedures governing the application for, and the processing of, special permits from the Department of Transportation's Hazardous Material Regulations (49 CFR part 107, subpart B), notice is hereby given that the Office of Hazardous Materials Safety has received the application described herein. This notice is abbreviated to expedite docketing and public notice. Because the sections affected, modes of transportation, and the nature of application have been shown in earlier Federal Register publications, they are not repeated here. Request of modifications of special permits (e.g. to provide for additional hazardous materials, packaging design changes, additional mode of transportation, etc.) are described in footnotes to the application number. Application numbers with the suffix ``M'' denote a modification request. These applications have been separated from the new applications for special permits to facilitate processing.
Office of Hazardous Materials Safety; Notice of Application for Special Permits

Airworthiness Directives; Airbus Model A310 Airplanes
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 cracking in the wing main landing gear (MLG) rib 5 forward attachment lug, which could affect the structural integrity of the MLG attachment. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
