We are adopting a new airworthiness directive (AD) for certain Textron Aviation, Inc. (type certificate previously held by Cessna Aircraft Company) Models 525, 525A, and 525B airplanes with Tamarack active load alleviation system (ATLAS) winglets installed in accordance with Supplemental Type Certificate (STC) SA03842NY. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product.

The purpose of this notice is to inform the public that the U.S. Department of Transportation (DOT) is planning to hold a conference entitled Traffic Safety and the 5.9 GHz Spectrum on June 3, 2019 to seek input regarding Vehicle-to-Everything (V2X) Communications. This event is a critical element for the Department in identifying areas of common ground that can assist deployers and investors in V2X technologies in advancing the use of the 5.9 GHz spectrum for traffic safety and congestion mitigation. The Department seeks to gain a greater understanding of industry leaders' current and future investment strategies, as well as potential considerations for efficient use of spectrum that will foster greater opportunities for some level of interoperability and compatibility moving forward.

This notice alerts transit agencies to the need to address the risk of transit operator assault when identified through the processes required under the Public Transportation Agency Safety Plan (PTASP) regulation. The PTASP regulation requires transit agencies to develop and implement Safety Management Systems (SMS) and associated processes for all elements of a public transportation system. In cases where transit agencies discover a risk of operator assault, the PTASP regulation requires agencies as part of their SMS processes to develop methods or processes to identify mitigations or strategies necessary as a result of the agency's safety risk assessment. The agency would use these methods or processes to reduce the likelihood and severity of occurrences of operator assault, based on the agency's analysis of the risk.
