Which US government agency is responsible for investigating all transportation-related incidents?

• A. Federal Aviation Administration (FAA)
• B. National Transportation Safety Board (NTSB)
• C. OAL
• D. Portable Oxygen Bottle (POB)

Answer: (B)

Investigating transportation incidents across modes is the job of the National Transportation Safety Board. This independent federal agency is responsible for determining the probable cause of accidents and serious incidents in aviation, highway, marine, rail, and pipeline transportation, and it issues safety recommendations to prevent reoccurrence. The Federal Aviation Administration, while in charge of regulating safety, certifying aircraft and pilots, and overseeing ongoing programs, does not investigate all incidents. The other options aren’t agencies that conduct these investigations, with one being not a relevant agency and the other referring to equipment rather than an investigative body.
