National Standards for Traffic Control Devices; the Manual on Uniform Traffic Control Devices for Streets and Highways; Maintaining Minimum Retroreflectivity of Longitudinal Pavement Markings
The Manual on Uniform Traffic Control Devices (MUTCD) is incorporated by reference in 23 CFR part 655, subpart F, approved by the Federal Highway Administration, and recognized as the national standard for traffic control devices used on all streets, highways, bikeways, and private roads open to public travel. The FHWA proposes to amend the MUTCD to include standards, guidance, options, and supporting information relating to maintaining minimum levels of retroreflectivity for pavement markings. The proposed revisions would establish a uniform minimum level of nighttime pavement marking performance based on the visibility needs of nighttime drivers. The proposed revisions will promote safety, enhance traffic operations, and facilitate comfort and convenience for all drivers, including older drivers. The proposed revisions described herein would be designated as Revision 1 to the 2009 Edition of the MUTCD.
Airworthiness Directives; Arrow Falcon Exporters, Inc. (previously Utah State University); California Department of Forestry; Firefly Aviation Helicopter Services (previously Erickson Air-Crane Co.); Garlick Helicopters, Inc.; Global Helicopter Technology, Inc.; Hagglund Helicopters, LLC (previously Western International Aviation, Inc.); International Helicopters, Inc.; Precision Helicopters, LLC; Robinson Air Crane, Inc.; San Joaquin Helicopters (previously Hawkins and Powers Aviation, Inc.); S.M.&T. Aircraft (previously US Helicopters, Inc., UNC Helicopter, Inc., Southern Aero Corporation, and Wilco Aviation); Smith Helicopters; Southern Helicopter, Inc.; Southwest Florida Aviation International, Inc. (previously Jamie R. Hill and Southwest Florida Aviation); Tamarack Helicopters, Inc. (previously Ranger Helicopter Services, Inc.); US Helicopter, Inc. (previously UNC Helicopter, Inc.); West Coast Fabrication; and Williams Helicopter Corporation (previously Scott Paper Co.) Model AH-1G, AH-1S, HH-1K, TH-1F,
This document proposes superseding an existing airworthiness directive (AD) for Model HH-1K, TH-1F, TH-1L, UH-1A, UH-1B, UH-1E, UH- 1F, UH-1H, UH-1L, and UH-1P helicopters; and Southwest Florida Aviation Model SW204, SW204HP, SW205, and SW205A-1 helicopters, manufactured by Bell Helicopter Textron, Inc. (BHTI) for the Armed Forces of the United States. That AD currently requires updating the product identification, extending the application of the AD to other helicopter models, continuing the existing retirement time for certain main rotor tension- torsion (TT) straps, and adding the TT strap part numbers to the applicability. This action proposes to require removing certain serial- numbered TT straps from service, reduce the retirement life for other TT straps, and establish a retirement life in terms of calendar time in addition to hours time-in-service (TIS) for certain other affected TT straps. This action would also add two model helicopters to the applicability of the AD. This proposal is prompted by fatigue cracking in certain TT straps that have stainless steel filament windings and a determination that corrosion damage, which is related to calendar time, necessitates a calendar time retirement life for certain TT straps in addition to the retirement life based on hours TIS. This proposal is also prompted by fatigue cracking in other TT straps with encased thin stainless steel plates. These proposals are based on the service history of helicopters that are the same or similar in type design to the helicopters to which this AD would apply. The actions specified by the proposed AD are intended to prevent failure of a TT strap, loss of a main rotor blade, and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (ECF) Model SA-365N1, AS-365N2, AS 365 N3, EC 155B, and EC155B1 Helicopters
We propose to adopt a new airworthiness directive (AD) for the specified ECF model helicopters. This proposed AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD reports the separation and loss of a stainless steel ring (75 millimeter (mm) in diameter) from a tail rotor blade (blade) sleeve resulting in severe, high-frequency vibrations, which can lead to damage to the fenestron blades, loss of yaw control, and subsequent loss of control of the helicopter.
Availability of the Draft Environmental Impact Statement
The FHWA, on behalf of the California Department of Transportation (Caltrans), announces the availability of the Draft Environmental Impact Statement (EIS) for a proposed highway project and route adoption study in San Benito and Santa Clara Counties, California.
Petition for Approval of Alternate Odometer Disclosure Requirements
The State of Wisconsin has petitioned for approval of alternate odometer requirements to certain requirements under Federal odometer law. NHTSA has initially determined that Wisconsin's alternate requirements satisfy Federal odometer law, with limited exceptions. Accordingly, NHTSA has preliminarily decided to grant Wisconsin's petition on condition that before NHTSA makes a final determination, Wisconsin amends its program to meet all the requirements of Federal odometer law or demonstrates that it meets the requirements of Federal law. This document is not a final agency action.
Petition for Approval of Alternate Odometer Disclosure Requirements
The State of Texas has petitioned for approval of alternate requirements to certain requirements under Federal odometer law. NHTSA is issuing this final determination granting Texas's petition.
