What type of incidents does the NTSB focus on?

The National Transportation Safety Board (NTSB) plays a crucial role in the investigation of aviation accidents and incidents, focusing on a comprehensive range of occurrences that can affect aviation safety. By choosing all types of aviation accidents and incidents as the focus, the NTSB ensures that it captures the entirety of factors contributing to safety in the aviation industry. This includes not only fatal accidents but also non-fatal incidents, near-misses, and incidents that may not involve aircraft crashes at all.

Investigating a broad spectrum of accidents allows the NTSB to identify patterns, recommend safety improvements, and develop regulations aimed at enhancing overall aviation safety. This comprehensive approach ensures that lessons are learned from both significant and minor events, which can ultimately help prevent future incidents, ensuring a more robust regulatory framework within the aviation sector.

In contrast, other options focus too narrowly, whether on only fatal accidents, specific types of errors, or mechanical failures, which limits the ability to draw broader safety conclusions across the entire aviation landscape.
