Department of Transportation April 2023 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by several unscheduled PW1500G engine removals due to certain crew alerting system (CAS) messages being displayed, high vibration, or debris found on the magnetic chip collector of a bearing compartment. This AD prohibits dispatch of an airplane with an affected engine having an applicable CAS message displayed, unless the bearing compartment chip collector and oil filter are inspected and any debris found is dispositioned, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

This proposed rule would update the existing Tribal Transportation Program Bridge Program, formerly known as the Indian Reservation Road (IRR) Bridge Program, by renaming it the Tribal Transportation Facility Bridge Program (TTFBP) to comply with the changes made in the Moving Ahead for Progress in the 21st Century Act (MAP-21), carried on through the Fixing America's Surface Transportation (FAST) Act, and the recent changes made by the Bipartisan Infrastructure Law (BIL), enacted as the Infrastructure Investment and Jobs Act (IIJA). It would also remove references to terms such as structurally deficient, functionally obsolete, and sufficiency rating. These updates would align the TTFBP terminology for bridge conditions with the terminology used for State departments of transportation (State DOT) in the Federal-aid highway program. This change would establish a consistent terminology for classifying and referring to bridge conditions.

The Federal Aviation Administration (FAA) announces that the Draft Programmatic Environmental Assessment (PEA) for FAA-Recognized Identification Areas (FRIAs) is available for public review and comment.
