Department of Transportation August 2, 2018 – Federal Register Recent Federal Regulation Documents

The Board is seeking comment on whether to make adjustments to its 2017 annual cost of capital determination, revenue adequacy determination, and Uniform Railroad Costing System calculations, to account for a one-time revaluation of rail carriers' deferred tax liabilities due to the reduction of the federal corporate income tax rate in the Tax Cuts and Jobs Act enacted in December 2017.

We propose to supersede airworthiness directive (AD) 2015-04- 04 for Bell Helicopter Textron Inc. (Bell) Model 412 and 412EP helicopters. AD 2015-04-04 requires revising the Rotorcraft Flight Manual (RFM) and installing a placard to limit flights to visual flight rules (VFR) and prohibiting night operations because of failing inverters. This proposed AD would require replacing the inverters with a new inverter. The actions in this proposed AD are intended to correct an unsafe condition on these products.

We propose to supersede Airworthiness Directive (AD) 2013-11- 03, which applies to certain Viking Air Limited Model CL-215-1A10 and CL-215-6B11 (CL-215T Variant) airplanes. AD 2013-11-03 requires repetitive detailed inspections for cracking of the left-hand (LH) and right-hand (RH) wing lower skin, and repair if necessary. AD 2013-11-03 was prompted by reports of a fractured wing lower rear spar cap and reinforcing strap. Since we issued AD 2013-11-03, further analysis has indicated the need for repetitive eddy current and borescope inspections. This proposed AD would require repetitive borescope inspections of the LH and RH wing lower skin and repetitive eddy current inspections of the LH and RH wing front and rear lower spar caps. We are proposing this AD to address the unsafe condition on these products.

We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by leakage of shrouded pipe T-boxes in the potable water system. This proposed AD would require replacement of the affected potable water T-boxes and clamps with new parts. We are proposing this AD to address the unsafe condition on these products.

This action proposes to modify Class E airspace extending upward from 1,200 feet above the surface in Alaska at Nuiqsut Airport; Oooguruk Island Heliport Nuiqsut; Pioneer Heliport, Nuiqsut; Perryville Airport; Pilot Point Airport; and Point Lay Airport. This proposal would add exclusionary language to the legal descriptions of these airports to exclude Class E airspace extending beyond 12 miles from the shoreline, and would ensure the safety and management of aircraft within the National Airspace System. Also, this action would remove the heliport name from the airspace designation of Oooguruk Island Heliport and Pioneer Heliport.
