Department of Transportation October 27, 2023 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for all De Havilland Aircraft of Canada Limited Model DHC-8-401 and - 402 airplanes. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.

The FHWA invites public comments about our intention to request the Office of Management and Budget's (OMB) approval for an information collection, which is summarized below under SUPPLEMENTARY INFORMATION. We are required to publish this notice in the Federal Register by the Paperwork Reduction Act of 1995.

In accordance with the Paperwork Reduction Act of 1995, FMCSA announces its plan to submit the Information Collection Request (ICR) described below to the Office of Management and Budget (OMB) for its review and approval and invites public comment. In order to work continuously to ensure that our programs are effective and meet our customers' needs, FMCSA requests approval to renew an ICR titled, ``Generic Clearance of Customer Satisfaction Surveys.'' This ICR allows FMCSA to continue collecting feedback on our service delivery. By feedback, we mean information that provides useful insights on perceptions and opinions but are not statistical surveys that yield quantitative results that can be generalized to the population of study.

The FAA is considering a proposal to change 0.577 acres of airport land from aeronautical use to non-aeronautical use and to authorize the sale of airport property located at Indianapolis Regional Airport, Indianapolis, Indiana. The aforementioned land is not needed for aeronautical use. The land is made up of two parcels and is located along the County Road 600 in Hancock County, just east of Indianapolis Regional Airport, Indianapolis, Indiana. The Sponsor is proposing to release and ultimately sell the land for future public use.

The Secretary of Transportation, as represented by the Maritime Administration (MARAD), is authorized to issue coastwise endorsement eligibility determinations for foreign-built vessels which will carry no more than twelve passengers for hire. A request for such a determination has been received by MARAD. By this notice, MARAD seeks comments from interested parties as to any effect this action may have on U.S. vessel builders or businesses in the U.S. that use U.S.-flag vessels. Information about the requestor's vessel, including a brief description of the proposed service, is listed below.

The FAA proposes to supersede airworthiness directive (AD) 2021-13-07, which applies to all GE Aviation Czech s.r.o. (GEAC) (type certificate previously held by WALTER Engine a.s., Walter a.s., and MOTORLET a.s.) Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E- 11S, and M601F engines. AD 2021-13-07 requires recalculating the life of critical parts and, depending on the results of the recalculation, replacing these critical parts. AD 2021-13-07 also requires replacing a certain compressor case. Since the FAA issued AD 2021-13-07, the manufacturer published the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM), which includes the calculations for the life of critical parts addressed by AD 2021-13-07 and prompted this proposed AD. This proposed AD would continue to require the replacement of a certain centrifugal compressor case. This proposed AD would also include an additional part number as an option for the replacement and would limit the applicability of the proposed AD, 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.
