Aircraft Accident Investigation is a systematic process aimed at determining the causes of aviation accidents. This involves collecting and analyzing evidence from the accident site, including wreckage, flight data, and witness statements. Investigators work to understand what happened during the flight and identify any contributing factors. The findings from these investigations are crucial for improving aviation safety. Recommendations may lead to changes in aircraft design, pilot training, or regulations to prevent similar accidents in the future. Ultimately, the goal is to enhance the safety of air travel for everyone.
