Annual Materials Report on New Bridge Construction and Bridge Rehabilitation
Section 1114 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) (Pub. L. 109-59; 119 Stat. 1144) continued the highway bridge program to enable States to improve the condition of their highway bridges over waterways, other topographical barriers, other highways, and railroads. Section 1114(f) amends 23 U.S.C. 144 by adding subsection (r), requiring the Secretary of Transportation (Secretary) to publish in the Federal Register a report describing construction materials used in new Federal-aid bridge construction and bridge rehabilitation projects.
Supplemental Notice for the National Parks Overflights Advisory Group Aviation Rulemaking Committee Meeting
The Federal Aviation Administration (FAA) and the National Park Service (NPS), in accordance with the National Parks Air Tour Management Act of 2000, announce the next meeting of the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). This notification provides the dates, location, and agenda for the meeting. This notification revises Federal Register notice published on August 19, 2008 (Vol. 73, No. 161, Page 48427-48428) to indicate a change in the time of meetings and that interested persons may attend the meeting.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and - 500 series airplanes. The original NPRM would have required doing repetitive internal eddy current and detailed inspections to detect cracked stringer tie clips; measuring the fastener spacing and the edge margin if applicable, and doing applicable corrective and related investigative actions. As a temporary alternative to doing the actions described previously, the original NPRM would have required repetitive inspections of the skin and lap joints for cracks and evidence of overload resulting from cracked stringer tie clips, and applicable corrective actions if necessary. The original NPRM resulted from a report of several cracked stringer tie clips. This action revises the original NPRM by including repetitive external eddy current sliding probe inspections of the lap joints for cracks and evidence of overload resulting from cracked stringer tie clips. We are proposing this supplemental NPRM to detect and correct multiple adjacent cracked stringer tie clips and damaged skin and frames, which could lead to the skin and frame structure developing cracks and consequent decompression of the airplane.
Airworthiness Directives; Saab Model SAAB 2000 Airplanes
We are revising an earlier NPRM for the products listed above. This action revises the earlier NPRM by expanding the scope. 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:
Airworthiness Directives; Boeing Model 777 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 777 airplanes. The existing AD requires, for the drive mechanism of the horizontal stabilizer, repetitive detailed inspections for discrepancies, repetitive lubrication of the ballnut and ballscrew, repetitive measurements of the freeplay between the ballnut and the ballscrew, and corrective action if necessary. This proposed AD would revise the compliance times of the existing AD. This proposed AD results from a report of extensive corrosion of a ballscrew in the drive mechanism of the horizontal stabilizer on a Boeing Model 757 airplane, which is similar in design to the ballscrew on Model 777 airplanes. We are proposing this AD to prevent an undetected failure of the primary load path for the ballscrew in the drive mechanism of the horizontal stabilizer and subsequent wear and failure of the secondary load path, which could lead to loss of control of the horizontal stabilizer and consequent loss of control of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 Airplanes; Model DC-8-51, DC-8-52, DC-8-53, and DC-8-55 Airplanes; Model DC-8F-54 and DC-8F-55 Airplanes; Model DC-8-61, DC-8-62, and DC-8-63 Airplanes; Model DC-8-61F, DC-8-62F, and DC-8-63F Airplanes; Model DC-8-71, DC-8-72, and DC-8-73 Airplanes; and Model DC-8-71F, DC-8-72F, and DC-8-73F Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all McDonnell Douglas Model DC-8 airplanes. The original NPRM would have superseded an existing AD that currently requires, among other things, revision of an existing program of structural inspections. The original NPRM proposed to require implementation of a revised program of structural inspections of baseline structure to detect and correct fatigue cracking in order to ensure the continued airworthiness of these airplanes as they approach the manufacturer's original fatigue design life goal. The original NPRM resulted from a significant number of these airplanes approaching or exceeding the design service goal on which the initial type certification approval was predicated. This new action revises the original NPRM by reducing the inspection threshold for certain principal structural elements. We are proposing this supplemental NPRM to detect and correct fatigue cracking that could compromise the structural integrity of these airplanes.
Airworthiness Directives; McDonnell Douglas Model DC-9-30, DC-9-40, and DC-9-50 Series Airplanes, Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) Airplanes, and Model MD-88 and MD-90-30 Airplanes
We propose to adopt a new airworthiness directive (AD) for the McDonnell Douglas airplanes listed above. This proposed AD would require modifying the fuel boost pumps for the center wing, and forward or aft auxiliary fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent possible sources of ignition in a fuel tank caused by an electrical fault or uncommanded dry operation of the fuel boost pumps. An ignition source in the fuel tank could result in a fire or an explosion and consequent loss of the airplane.
Airworthiness Directives; Dowty Propellers R175/4-30; R184/4-30-4; R193/4-30-4; R.209/4-40-4.5; R212/4-30-4; R.245/4-40-4.5; R251/4-30-4; R257/4-30-4; and R.259/4-40-4.5 Model Propellers
The FAA proposes to supersede an existing airworthiness directive (AD) for all Dowty Rotol propellers. That AD currently requires, for all Dowty Rotol propellers, visual inspections for seizure and for cadmium plating of the blade pitch change operating links and eyebolt fork assemblies. That AD also requires replacement or heat-treatment of the blade pitch change operating links and eyebolt fork assemblies, if necessary. This proposed AD would require the same actions, but only for certain model Dowty Propellers. This proposed AD results from the FAA determining that AD 70-16-02 does not apply to all propellers, since current Dowty Rotol propellers are differently designed. We are proposing this AD supersedure to specify the affected propeller models, and to prevent seizure or embrittlement and cracking of the blade pitch change operating links and eyebolt fork assemblies, which could result in reduced controllability of the airplane.
Decision that Certain Nonconforming Motor Vehicles Are Eligible for Importation
This document announces decisions by NHTSA that certain motor vehicles not originally manufactured to comply with all applicable Federal motor vehicle safety standards (FMVSS) are eligible for importation into the United States because they are substantially similar to vehicles originally manufactured for sale in the United States and certified by their manufacturers as complying with the safety standards, and they are capable of being readily altered to conform to the standards or because they have safety features that comply with, or are capable of being altered to comply with, all applicable FMVSS.
Plan for Evaluating the Effectiveness of Vehicle and Behavioral Programs, 2008-2012
This notice announces the publication by NHTSA of its Evaluation Program Plan for 2008-2012. The report describes the agency's ongoing and planned evaluations of its existing Federal Motor Vehicle Safety Standards [49 CFR part 571] and other vehicle-safety, behavioral-safety and consumer programs. It also summarizes the results of completed evaluations. The agency's evaluation program responds to Executive Order 12866, which provides for Government-wide review of existing significant Federal regulations. This notice solicits public review and comment on the evaluation plan. Comments received will be used to improve the plan.
Qualification and Certification of Locomotive Engineers
FRA is issuing this notice of interpretation to inform interested parties of its application and enforcement of the requirements for each railroad responsible for controlling joint operations territory to maintain a list of person(s) certified as a qualified locomotive engineer for the purposes of the joint operations. FRA has discovered that a number of controlling railroads are not maintaining accurate lists primarily because foreign railroads are not providing the controlling railroads with accurate information and the controlling railroads are not demanding it. If an accurate list is not maintained, a controlling railroad has little chance of preventing an uncertified or unqualified person from operating a locomotive or train in the joint operations territory. This document is intended to inform interested parties of what information is required to be maintained on the required list and provides information as to how often the listings should be updated.
Railroad Safety Advisory Committee (RSAC); Working Group Activity Update
FRA is updating its announcement of RSAC's working group activities to reflect its current status.
Railroad Safety Advisory Committee; Notice of Meeting
FRA announces the 36th meeting of the RSAC, a Federal advisory committee that develops railroad safety regulations through a consensus process. The RSAC meeting topics will include opening remarks from the FRA Administrator, and status reports will be provided by the Passenger Safety, Locomotive Safety Standards, Railroad Bridge, Medical Standards, Railroad Operating Rules, and Track Safety Standards Working Groups. There will be a Committee vote on the acceptance of the report from the Railroad Bridge Working Group and a possible vote on an expanded task statement for the Track Standards Working Group. Accident/incident reporting is on the agenda for discussion by the Committee and there may be a vote on a contingent task statement. This agenda is subject to change.
