Buy America Waiver Notification
This notice provides information regarding FHWA's finding that a Buy America waiver is appropriate for the obligation of Federal-aid funds for 75 State projects involving the acquisition of vehicles and equipment on the condition that they be assembled in the U.S.
Membership in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
By Federal Register notice (See 79 FR 77594-77595, December 24, 2014) the National Park Service (NPS) and the Federal Aviation Administration (FAA) invited interested persons to apply to fill two existing openings and one upcoming opening on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). The notice invited interested persons to apply to fill two currently vacant seats representing environmental concerns and one future opening to represent Native American interests. This notice informs the public of the persons selected to fill these current and future vacancies.
Operation and Certification of Small Unmanned Aircraft Systems
The FAA is proposing to amend its regulations to adopt specific rules to allow the operation of small unmanned aircraft systems in the National Airspace System. These changes would address the operation of unmanned aircraft systems, certification of their operators, registration, and display of registration markings. The proposed rule would also find that airworthiness certification is not required for small unmanned aircraft system operations that would be subject to this proposed rule. Lastly, the proposed rule would prohibit model aircraft from endangering the safety of the National Airspace System.
Airworthiness Directives; the Boeing Company Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. The NPRM proposed to require modifying the fuel quantity indication system (FQIS) wiring or fuel tank systems to prevent development of an ignition source inside the center fuel tank. The NPRM was prompted by fuel system reviews conducted by the manufacturer. This action revises the NPRM by revising the applicability, including optional actions for cargo airplanes, and extending the compliance time. We are proposing this supplemental NPRM (SNPRM) to prevent ignition sources inside the center fuel tank, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane. Since these actions significantly change the corrective action options for cargo airplanes relative to the proposal in the NPRM, and because the cost estimate is significantly revised, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. This AD requires inspection of the oil feed tube sealing sleeve and removal of those oil feed tube sealing sleeves that are affected by this AD. This AD was prompted by fractures of the high- pressure/intermediate-pressure (HP/IP) turbine support internal oil feed tube. We are issuing this AD to prevent failure of the HP/IP turbine support internal oil feed tube, which could result in uncontained engine failure and damage to the airplane.
Airworthiness Directives; Short Brothers & Harland Ltd. Airplanes
We are adopting a new airworthiness directive (AD) for Short Brothers & Harland Ltd. Model SC-7 Series 3 airplanes. 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 fatigue cracking, which could lead to structural failure of the nose landing gear (NLG). We are issuing this AD to require actions to address the unsafe condition on these products.
Hazardous Materials: Transportation of Lithium Batteries
PHMSA is extending for modes of transportation other than air the mandatory compliance date of a final rule published on August 6, 2014, under Docket No. HM-224F from February 6, 2015, until August 7, 2015. This extension is made in response to formal comments received from multiple stakeholders outlining challenges faced by the regulated community in fully implementing the provisions of the final rule by the February 6, 2015 mandatory compliance date.
Research and Development Program Forum
This notice is to advise interested persons that PHMSA will host a Research and Development Forum on Thursday, April 16, 2015, in Washington, DC. PHMSA will use the forum to present the results of recently completed research projects and to discuss current and future research projects. PHMSA will also be soliciting comments on new research projects which may be considered for inclusion in its strategic plan.
Qualification of Drivers; Exemption Applications; Vision
FMCSA announces its decision to exempt 24 individuals from the vision requirement in the Federal Motor Carrier Safety Regulations (FMCSRs). They are unable to meet the vision requirement in one eye for various reasons. The exemptions will enable these individuals to operate commercial motor vehicles (CMVs) in interstate commerce without meeting the prescribed vision requirement in one eye. The Agency has concluded that granting these exemptions will provide a level of safety that is equivalent to or greater than the level of safety maintained without the exemptions for these CMV drivers.
Asset Management Plan
The FHWA proposes to establish a process for the development of a State asset management plan in accordance with section 1106 of the Moving Ahead for Progress in the 21st Century Act (MAP-21), to improve or preserve the condition of the assets and the performance of the National Highway System (NHS) as they relate to physical assets. In this document ``asset management plan'' and ``risk-based asset management plan'' are used interchangeably. An asset management plan is a key management tool for highway infrastructure owners. State departments of transportation (State DOT) increasingly use asset management plans to make decisions about where and when to invest State and Federal funds in highway infrastructure improvements to achieve and sustain a desired state of good repair over the life cycle of the assets at minimum practicable cost. The development and implementation of an asset management plan also is an important part of the overall MAP-21 framework for enhancing the management and performance of transportation highway infrastructure funded through the Federal-aid highway program (FAHP). The asset management plan required by section 1106 of MAP-21 will provide States with critical data and identify investment and management strategies to improve or preserve the condition of the assets and the performance of the NHS. Under section 1106, the plan must include strategies leading to a program of projects that would make progress toward achievement of the State targets for asset condition and performance of the NHS in accordance with section 1203(a) of MAP-21, and supporting progress toward the achievement of the national goals identified in section 1203(a). While the primary purpose of this proposed rule is to address asset management plan requirements in section 1106, this proposed rule also would address other MAP-21 requirements that relate to asset management. The proposed rule defines the minimum standards that States would use in developing and operating highway bridge and pavement management systems as required by section 1203(a) of MAP-21. Also, this proposed rule would address the requirements in section 1315(b) of MAP- 21 by requiring States to conduct statewide evaluations to determine if reasonable alternatives exist to roads, highways, or bridges that repeatedly require repair and reconstruction activities from emergency events. The proposed rule would require State DOTs to take these evaluations into account in their asset management plans for facilities that are included in the plans.

Railroad Cost Recovery Procedures-Productivity Adjustment
In a decision served on February 13, 2015, we proposed to adopt 1.007 (0.7% per year) as the measure of average change in railroad productivity for the 2009-2013 (5-year) averaging period. This value represents a decrease of 0.3% from the average for the 2008-2012 period. The Board's February 13, 2015 decision in this proceeding stated that comments may be filed addressing any perceived data and computational errors in our calculation. It also stated that, if there were no further action taken by the Board, the proposed productivity adjustment would become effective on March 1, 2015.
Public Notice for Waiver of Aeronautical Land-Use Assurance
The FAA is considering a proposal to change 22.212 acres of airport land from the federal obligation dedicating it to aeronautical use and to authorize this land to be used for revenue producing, non- aeronautical purposes at Indianapolis International Airport, Indianapolis, Indiana. The aforementioned land is not needed for current or future aeronautical use. The land is north of the Indianapolis Maintenance Center, west of the Indianapolis Maintenance Center's central energy plant, and industrial waste water treatment facility located just south of U.S. Route 40 and west of Brushwood Road. The land is not currently developed. A solar power generating facility is proposed for development on the land.

They are unable to meet the vision requirement in one eye for various reasons. The exemptions will enable these individuals to operate commercial motor vehicles (CMVs) in interstate commerce without meeting the prescribed vision requirement in one eye. The Agency has concluded that granting these exemptions will provide a level of safety that is equivalent to or greater than the level of safety maintained without the exemptions for these CMV drivers.
Qualification of Drivers; Exemption Applications; Diabetes Mellitus
FMCSA confirms its decision to exempt 66 individuals from its rule prohibiting persons with insulin-treated diabetes mellitus (ITDM) from operating commercial motor vehicles (CMVs) in interstate commerce. The exemptions enable these individuals to operate CMVs in interstate commerce.
Railroad Cost of Capital-2014
The Board is instituting a proceeding to determine the railroad industry's cost of capital for 2014. The decision solicits comments on the following issues: (1) The railroads' 2014 current cost of debt capital; (2) the railroads' 2014 current cost of preferred equity capital (if any); (3) the railroads' 2014 cost of common equity capital; and (4) the 2014 capital structure mix of the railroad industry on a market value basis. Comments should focus on the various cost of capital components listed above using the same methodology followed in Railroad Cost of Capital2013, EP 558 (Sub-No. 17) (STB served July 31, 2014).
Qualification of Drivers; Exemption Applications; Diabetes Mellitus
FMCSA announces receipt of applications from 78 individuals for exemption from the prohibition against persons with insulin-treated diabetes mellitus (ITDM) operating commercial motor vehicles (CMVs) in interstate commerce. If granted, the exemptions would enable these individuals with ITDM to operate CMVs in interstate commerce.

Notice of Rail Energy Transportation Advisory Committee Meeting
Notice is hereby given of a meeting of the Rail Energy Transportation Advisory Committee (RETAC), pursuant to the Federal Advisory Committee Act (FACA), 5 U.S.C. app. 2 section 10(a)(2).
Notice of Buy America Waiver for Track Turnout Components
In response to a request from the Long Island Rail Road Company (LIRR), a subsidiary of the New York Metropolitan Transportation Authority (MTA), for a Buy America waiver for track turnout components, the Federal Transit Administration (FTA) hereby waives its Buy America requirements for LIRR's procurement of the following track turnout components: Schwihag roller assemblies, Schwihag plates, ZU1-60 steel switch point rail sections, and movable point frogs. This waiver is limited to LIRR's procurement of these track turnout components for the nine (9) turnouts that LIRR needs for VHL03 LIRR Stage 3 of the East Side Access Project and the one (1) turnout that LIRR needs for VHL04 LIRR Stage 4 of the East Side Access Project. The turnouts themselves, however, are subject to FTA's Buy America requirements and, accordingly, the turnouts must be manufactured in the United States. This Buy America waiver does not apply to the track turnout components for Phase I of LIRR's Jamaica Capacity Improvements Project, and FTA will address that waiver request separately. Moreover, this Buy America waiver does not apply to the track turnout components for the Northeast Corridor Congestion Relief Project at Harold Interlocking, which is being addressed in a separate waiver decision published by the Federal Railroad Administration (FRA), as FRA funds are being used for that project.
Qualification of Drivers; Exemption Applications; Vision
FMCSA announces its decision to renew the exemptions from the vision requirement in the Federal Motor Carrier Safety Regulations for 17 individuals. FMCSA has statutory authority to exempt individuals from the vision requirement if the exemptions granted will not compromise safety. The Agency has concluded that granting these exemption renewals will provide a level of safety that is equivalent to or greater than the level of safety maintained without the exemptions for these commercial motor vehicle (CMV) drivers.
Parts and Accessories Necessary for Safe Operation; Application for an Exemption From Virginia Tech Transportation Institute (VTTI)
The Federal Motor Carrier Safety Administration (FMCSA) requests public comment on an application for exemption from VTTI to allow the placement of camera-based data acquisition systems (DAS) at the bottom of windshields on commercial motor vehicles (CMVs). The Federal Motor Carrier Safety Regulations (FMCSRs) currently require antennas, transponders, and similar devices to be located not more than 6 inches below the upper edge of the windshield, outside the area swept by the windshield wipers, and outside the driver's sight lines to the road and highway signs and signals. VTTI is coordinating device development and installation of the DASs for a National Highway Traffic Safety Administration (NHTSA) research program in up to 150 CMVs. The exemption would enable VTTI and NHTSA to conduct research on the reliability of collision avoidance systems for CMVs. VTTI believes that mounting the DASs at the bottom of the windshield would maintain a level of safety that is equivalent to, or greater than, the level of safety achieved without the exemption.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2012-24- 10, which applies to certain The Boeing Company Model 747-400 and -400F series airplanes. AD 2012-24-10 currently requires installing new software, replacing the duct assembly with a new duct assembly, making wiring changes, and routing certain wire bundles. Since we issued AD 2012-24-10, we have received new reports of intermittent or blank displays of a certain integrated display unit (IDU) that were due to an intermittent false ground not addressed by the software installation or wiring changes required by AD 2012-24-10. This proposed AD would retain the requirements of AD 2012-24-10 and would require installing a new or serviceable pressure switch bracket and altitude pressure switch, and add an airplane to the applicability of the existing AD. We are proposing this AD to prevent IDU malfunctions, which could affect the ability of the flightcrew to read primary displays for airplane attitude, altitude, or airspeed, and consequently reduce the ability of the flightcrew to maintain control of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, and F4- 600R series airplanes, and A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This proposed AD was prompted by reports of cracked aluminum support struts of the trimmable horizontal stabilizer (THS) caused by stress corrosion. This proposed AD would require inspections to identify the part number of each support strut, repetitive inspections for cracking of the THS support strut ends, installation of reinforcing clamps on strut ends, and replacement of support struts, if necessary. We are proposing this AD to detect and correct cracked THS support struts, which could lead to the rupture of all four support struts making the remaining structure unable to carry limit loads, which could result in loss of the THS and reduced control of the airplane.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 B4-603, B4-605R, B4-620, B4-622, B4-622R airplanes; all Airbus Model A300 C4-605R Variant F airplanes; and certain Airbus Model A300 F4-605R airplanes. This proposed AD was prompted by the manufacturer's review of all repairs accomplished using the structural repair manual. This review was done using revised fatigue and damage tolerance calculations. This proposed AD would require an inspection of the surrounding panels of the left and right forward passenger doors, and corrective actions if necessary. We are proposing this AD to detect and correct previous incomplete or inadequate repairs to the surrounding panels of the left and right forward passenger doors and the fail-safe ring, which could negatively affect the structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2012-09-07 for certain Airbus Model A319-111, -112, and -132 airplanes; Model A320- 111, -211, -212, -214, and -232 airplanes; and Model A321-111, -211, - 212, and -231 airplanes. AD 2012-09-07 required an electrical bonding test between the gravity fill re-fuel adaptor and the top skin panels on the wings; and, if necessary, an inspection for corrosion of the component interface and adjacent area; and repairing the gravity fuel adaptor if necessary. This new AD adds airplanes to the applicability and requires inspecting those airplanes to determine if a repair was done, and doing the electrical bonding test and corrective action if necessary. This AD was prompted by a determination that more airplanes are subject to the identified unsafe condition. We are issuing this AD to detect and correct corrosion and improper bonding, which, in combination with a lightning strike in this area, could create a source of ignition in a fuel tank, resulting in a fire or explosion and consequent loss of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This proposed AD was prompted by testing of the spoiler electronic control unit (SECU) software for an upgrade, which revealed a timing error between the command and monitor channels. This proposed AD would require revising the maintenance or inspection program to incorporate repetitive operational tests of the aileron disconnect system, and corrective action if necessary. This proposed AD would also require modification and reidentification of the SECU, which would terminate the repetitive operational tests. We are proposing this AD to prevent a timing error in the SECU software, which, in combination with failure of the roll disconnect switch, could result in complete loss of spoiler functionality and consequent reduced controllability of the airplane.
