Aviation investigators are specialized professionals who examine accidents and incidents involving aircraft. Their primary goal is to determine the causes of these events to improve safety and prevent future occurrences. They analyze various factors, including mechanical failures, human error, and environmental conditions, using evidence from the crash site, flight data recorders, and witness accounts. These investigators often work for organizations like the National Transportation Safety Board (NTSB) in the United States or similar agencies worldwide. They collaborate with engineers, pilots, and other experts to gather information and produce detailed reports that outline their findings and recommendations for the aviation industry.
