Department of Transportation September 29, 2023 – Federal Register Recent Federal Regulation Documents

The Department of Transportation (DOT) invites public comments about our intention to request Office of Management and Budget (OMB) approval to renew information collection 2105-0529, Procedures for Transportation Drug and Alcohol Testing Program (ICR 2105-0529). The information to be collected will be used to document tests conducted and actions taken to ensure safety in the workplace and/or are necessary under the Omnibus Transportation Employee Testing Act of 1991, which requires DOT to implement a drug and alcohol testing program in various transportation-related industries. DOT is required to publish this notice in the Federal Register in accordance with the Paperwork Reduction Act of 1995.

The Moving Ahead for Progress in the 21st Century Act established the Surface Transportation Project Delivery Program (referred to as National Environmental Policy Act (NEPA) Assignment Program), allows a State to assume FHWA's environmental responsibilities for environmental review, consultation, and compliance under NEPA. When a State assumes these Federal responsibilities, the State becomes solely responsible and liable for carrying out the responsibilities it has assumed, in lieu of FHWA. This program mandates annual audits during each of the first 4 years of State participation to ensure compliance with program requirements. This is the third audit of the Arizona Department of Transportation's (ADOT) performance of its responsibilities under the NEPA Assignment Program. This notice announces and solicits comments on the third audit report for ADOT.

The FAA proposes to adopt a new airworthiness directive (AD) for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000-AE3, Trent 1000-CE3, Trent 1000-D3, Trent 1000-G3, Trent 1000-H3, Trent 1000-J3, Trent 1000-K3, Trent 1000-L3, Trent 1000-M3, Trent 1000-N3, Trent 1000-P3, Trent 1000-Q3, and Trent 1000-R3 engines. This proposed AD was prompted by a determination that certain intervals for visual inspection of the intermediate-pressure stage 8 (IP8) and high-pressure stage 3 (HP3) air transfer tubes and front bearing housing IP8 air feed tubes need to be reduced. This proposed AD would require initial and repetitive visual inspections of the IP8 and HP3 air transfer tubes and front bearing housing IP8 air feed tubes for cracking, damage, or air leakage wear, and replacement, if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

This action proposes to modify the Class E airspace extending upward from 700 feet above the surface and remove the Class E airspace extending upward from 1200 feet above the surface at Klawock Airport, Klawock, AK. Additionally, this action proposes administrative amendments to update the airport's existing Class E airspace legal description. These actions would support the safety and management of instrument flight rules (IFR) operations at the airport.

The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-100-1A10 airplanes. This proposed AD was prompted by reports from the supplier that some overheat detection sensing elements of the bleed air leak detection system were manufactured with insufficient salt fill, which can result in an inability to detect hot bleed air leaks. This proposed AD would require revising the existing airplane flight manual (AFM) to include procedures to prevent takeoff with an active bleed air leak annunciated while on the ground. This proposed AD would also require testing the overheat detection sensing elements, marking each serviceable sensing element with a witness mark, and replacing each nonserviceable part with a serviceable part. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
