Which organization is abbreviated as NTSB?

The organization abbreviated as NTSB stands for the National Transportation Safety Board. This independent U.S. government agency is responsible for investigating accidents in various modes of transportation, including aviation, rail, highway, marine, and pipeline incidents. The NTSB’s primary mission is to promote transportation safety by determining the probable cause of accidents and making recommendations to improve safety standards. Understanding the role of the NTSB is crucial for airport managers and personnel, as it directly relates to aviation safety, accident investigation, and regulatory compliance, which are vital areas for airport operations and management. The other options listed do not represent real organizations engaged in transportation safety, thereby reinforcing the correctness and significance of recognizing the proper title and function of the NTSB.
