Department of Transportation September 26, 2017 – Federal Register Recent Federal Regulation Documents

This action establishes restricted area R-2306F in the vicinity of Laguna Army Airfield (LGF) at Yuma Proving Ground, AZ. The restricted area allows Yuma Proving Ground (YPG) to maximize the existing fixed infrastructure to support current and future hazardous test programs while minimizing the risk to public and non-participating aircraft. These programs involve ground and airborne testing of non- eye-safe lasers, high energy radars and the development of unproven weapon systems and this ensures the safer testing and evaluation of these programs without impacting non-participating aircraft and general public.

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This proposed AD was prompted by a report of wire damage on a fuel boost pump power cable, and a separate report of a fuel tank explosion on a similarly equipped airplane. This proposed AD would require the installation of new shielded wire bundles and convoluted liners within fuel tank conduits, and revision of the maintenance or inspection program, as applicable, to incorporate certain airworthiness limitations (AWLs). We are proposing this AD to address the unsafe condition on these products.

FMCSA announces that it has received an application from the National Tank Truck Carriers, Inc. (NTTC) requesting exemption from the requirement that drivers of commercial motor vehicles (CMVs) obtain a 30-minute rest break. The exemption would enable drivers engaged in the transportation of petroleum-based fuels to use 30 minutes of time attending the load to satisfy the 30-minute rest break requirement. FMCSA requests public comment on NTTC's application for exemption.

Notice is hereby given of a meeting of the Rail Energy Transportation Advisory Committee (RETAC), pursuant to the Federal Advisory Committee Act (FACA).

This action modifies Class E airspace extending up to 700 feet above the surface at Wayne Municipal/Stan Morris Field (formally the Wayne Municipal Airport), Wayne, NE, to accommodate new standard instrument approach procedures for instrument flight rules (IFR) operations at the airport. This action is necessary due to the decommissioning of the Wayne non-directional radio beacon (NDB) serving the airport, and cancellation of the NDB approach. This action enhances the safety and management of IFR operations at the airport. The new airport name was not included in the NPRM and is being corrected. The geographic coordinates of the airport also are updated to be in concert with the FAA's aeronautical database.

We are adopting a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84, turbofan engines. This AD requires replacement of the low-pressure compressor (LPC) case support inboard pins. This AD was prompted by LPC case support inboard pins that may have reduced integrity due to incorrect heat treatment. We are issuing this AD to correct the unsafe condition on these products.
