Department of Transportation July 29, 2024 – Federal Register Recent Federal Regulation Documents

In compliance with the Paperwork Reduction Act of 1995 (PRA), this notice announces that the Information Collection Request (ICR) summarized below will be submitted to the Office of Management and Budget (OMB) for review and approval. The ICR describes the nature of the information collection and its expected burden. The National Highway Traffic Safety Administration (NHTSA) proposes to conduct a new information collection, the National Traffic Safety Survey, a national probability sample of approximately 6,001 adults aged 18 and older per survey administration. This information will be used to better understand the public's behavior and attitudes regarding traffic safety issues including seat belts, distracted driving, new and emerging vehicle technologies, and traffic safety and enforcement. A Federal Register Notice with a 60-day comment period soliciting comments on the following information collection was published on May 17, 2024. NHTSA received one comment in support of the proposed information collection.

The Maritime Administration (MARAD) invites public comments on our intention to request the Office of Management and Budget (OMB) approval to renew an information collection in accordance with the Paperwork Reduction Act of 1995. The proposed collection OMB 2133-0552 (Port Infrastructure Development Program) is being updated to reflect the elimination of the MA-1083 Port Infrastructure Development Program (PIDP) Project Information Form, which is no longer needed. The total respondents and public burden have also reduced since this collection was implemented in 2019. We are required to publish this notice in the Federal Register to obtain comments from the public and affected agencies.

The FAA proposes to supersede Airworthiness Directive (AD) 2023-24-06, which applies to certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 1000 engines. AD 2023-24-06 requires revising the airworthiness limitation section (ALS) of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts. Since the FAA issued AD 2023-24-06, the manufacturer revised the time limits manual (TLM) to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, which prompted this AD. This proposed AD would require revisions to the ALS of the operator's existing approved engine maintenance or inspection program, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

The FAA proposes to adopt a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model LEAP-1B engines. This proposed AD was prompted by a report of a quality escape involving certain high-pressure compressor (HPC) stage 2 seals manufactured without detailed finish machining, which could result in deeper rubs and mechanical damage to the seal teeth of the stage 3-4 compressor rotor blisk (stage 3-4 blisk) of the mating compressor rotor during initial operation. This proposed AD would require a visual inspection of the HPC stage 2 seal, a visual inspection of the forward arm seal teeth of the stage 3-4 blisk, an eddy current inspection (ECI) of the forward arm seal teeth of the stage 3-4 blisk, and replacement of the HPC stage 2 seal and the stage 3-4 blisk, if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
