Department of Transportation June 7, 2019 – Federal Register Recent Federal Regulation Documents

The Board is publishing, and providing the public an opportunity to comment on, the 2018 weighted average state tax rates for each Class I railroad, as calculated by the Association of American Railroads (AAR), for use in the Revenue Shortfall Allocation Method (RSAM).

We are adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 D-2 helicopters. This AD requires replacing the rescue hoist cable cut pushbutton flip guard (flip guard). This AD was prompted by reports of unintended lifting of several flip guards. We are issuing this AD to address the unsafe condition on these products.

The FAA is considering a request from Tulsa Airports Improvement Trust to change approximately 507 acres located on the east side of the airport between North Mingo Road and Highway 169 from aeronautical use to non-aeronautical use and to authorize the conversion of the airport property. The proposal consists of three parcels of land which were originally acquired under the following grants: Federal Airport Aid Program (FAAP) Nos. 9-34-032-C132 in 1963 and 3-34-032-C514 in 1965 and Airport Development Aid Program (ADAP) No.6-40-99-15 in 1978. The land comprising these parcels is outside the forecasted need for aviation development and is no longer needed for indirect or direct aeronautical use. The Airport wishes to develop this land for compatible commercial, non-aeronautical use. The Airport will retain ownership of this land and ensure the protection of Part 77 surfaces and compatible land use. The income from the conversion of these parcels will benefit the aviation community by reinvestment in the airport. Approval does not constitute a commitment by the FAA to financially assist in the conversion of the subject airport property nor a determination of eligibility for grant-in-aid funding from the FAA. The disposition of proceeds from the conversion of the airport property will be in accordance with FAA's Policy and Procedures Concerning the Use of Airport Revenue, published in the Federal Register on February 16, 1999. In accordance with section 47107(h) of Title 49, United States Code, this notice is required to be published in the Federal Register 30 days before modifying the land-use assurance that requires the property to be used for an aeronautical purpose.

In accordance with the procedures governing the application for, and the processing of, special permits from the Department of Transportation's Hazardous Material Regulations, notice is hereby given that the Office of Hazardous Materials Safety has received the application described herein.

We are superseding Airworthiness Directive (AD) 2012-25-02, which applied to certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2012-25-02 required revising the airworthiness limitations section (AWL) of the instructions for continued airworthiness (ICA) of the maintenance requirements manual (MRM) by incorporating new procedures for repetitive inspections for cracking of the rear pressure bulkhead (RPB). AD 2012-25-02 also required revising the maintenance or inspection program to incorporate a revised task. This AD also mandates modification of the RPB and adds repetitive inspections for cracking of the RPB web, which terminates certain actions in this AD. This AD was prompted by additional in- service crack findings, which resulted in the development of a structural modification to the RPB. We are issuing this AD to address the unsafe condition on these products.

FMCSA announces its decision to deny applications from seven individuals treated with Implantable Cardioverter Defibrillators (ICDs) who requested an exemption from the Federal Motor Carrier Safety Regulations (FMCSRs) prohibiting operation of a commercial motor vehicle (CMV) in interstate commerce by persons with a current clinical diagnosis of myocardial infarction, angina pectoris, coronary insufficiency, thrombosis, or any other cardiovascular disease of a variety known to be accompanied by syncope, dyspnea, collapse, or congestive heart failure.

FMCSA announces its decision to renew exemptions for 74 individuals from the vision requirement in the Federal Motor Carrier Safety Regulations (FMCSRs) for interstate commercial motor vehicle (CMV) drivers. The exemptions enable these individuals to continue to operate CMVs in interstate commerce without meeting the vision requirements in one eye.

FMCSA announces its decision to grant the application of RJR Transportation, Inc. (RJR) for an exemption to increase the 100 air- mile radius in ``short-haul operations'' to 150 air miles for its drivers. RJR requested the exemption for all its operators of commercial motor vehicles (CMVs) to enable the drivers not exceeding the 150 air-mile radius to utilize time records instead of a record of duty status (RODS) for that day. FMCSA has analyzed the exemption application and the public comments and has determined that the exemption, subject to the terms and conditions imposed, will likely achieve a level of safety that is equivalent to, or greater than, the level that would be achieved absent such exemption.

We are revising an earlier proposal for certain Bombardier, Inc., Model DHC-8-400 series airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding a requirement to replace the lower lock link of the nose landing gear (NLG), which would terminate the repetitive inspections proposed in the NPRM. This action also reduces the applicability in the NPRM. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these actions would impose an additional burden over those in the NPRM, we are reopening the comment period to allow the public the chance to comment on these changes.
