Which agency investigates aviation accidents and incidents in the United States?

The National Transportation Safety Board (NTSB) is the agency responsible for investigating aviation accidents and incidents in the United States. This independent federal agency focuses specifically on ensuring safety in transportation and is equipped to conduct thorough investigations into aircraft accidents, determining the causes and making recommendations aimed at preventing future occurrences.

The NTSB’s role includes conducting on-site investigations, collecting evidence, and analyzing data related to aviation accidents. Their findings can lead to safety improvements and regulatory changes, making air travel safer for everyone.

In contrast, the Federal Aviation Administration (FAA) is primarily responsible for regulating and overseeing civil aviation, including the safety of aircraft operations and air traffic control, but does not handle accident investigations. The Transportation Security Administration (TSA) focuses on passenger and baggage screening for security purposes, while the Occupational Safety and Health Administration (OSHA) deals with workplace safety regulations. Thus, the function of investigating aviation accidents is uniquely assigned to the NTSB.
