The National Transportation Safety Board (NTSB) is responsible for investigating specific types of transportation accidents. These include aviation accidents involving civil aircraft, highway accidents involving commercial motor vehicles, railroad accidents, pipeline accidents, and marine accidents. The NTSB also investigates major transportation-related disasters, such as the sinking of the Titanic or the crash of the Space Shuttle Columbia. The NTSB’s mission is to determine the probable cause of these accidents and make recommendations to prevent similar accidents from happening in the future.
NTSB’s Investigative Authority
The NTSB is responsible for investigating all civil aviation accidents within the United States and its territories, as well as any accidents involving U.S.-registered aircraft operating anywhere in the world. In addition, the NTSB has the authority to investigate any other type of transportation accident that it deems to be in the public interest, including:
Major Transportation Accidents
- Airliner crashes
- Train derailments
- Major highway accidents
Accidents Involving Hazardous Materials
- Train derailments involving hazardous chemicals
- Oil spills
- Pipeline explosions
Accidents Involving Critical Infrastructure
- Power plant accidents
- Bridge collapses
- Airport runway accidents
Accidents Involving New or Emerging Technologies
- Autonomous vehicle accidents
- Drone accidents
- High-speed rail accidents
The NTSB does not investigate accidents that are caused by natural disasters, such as earthquakes or hurricanes. In addition, the NTSB does not investigate criminal acts, as these are handled by law enforcement agencies.
| Category | Description |
|---|---|
| Major | Accidents involving fatalities or serious injuries, or significant damage to property. |
| Minor | Accidents involving only minor injuries or property damage. |
| Incident | Events that do not result in any injuries or property damage, but have the potential to cause an accident. |
Transportation Modes Covered by NTSB Investigations
The National Transportation Safety Board (NTSB) is responsible for investigating transportation accidents in the United States. These accidents include:
- Aviation accidents involving civil aircraft
- Railroad accidents involving trains
- Highway accidents involving commercial motor vehicles
- Pipeline accidents involving hazardous materials
- Marine accidents involving commercial vessels
The NTSB also investigates accidents involving the following:
- General aviation aircraft
- Small passenger vessels
- Recreational boats
- Off-road vehicles
| Transportation Mode | Types of Accidents Investigated |
|---|---|
| Aviation | Airplane crashes, helicopter crashes, glider crashes, balloon crashes |
| Railroad | Train derailments, train collisions, train-vehicle accidents |
| Highway | Truck accidents, bus accidents, tanker accidents, hazardous materials accidents |
| Pipeline | Pipeline leaks, pipeline explosions, pipeline ruptures |
| Marine | Shipwrecks, boat accidents, ferry accidents, barge accidents |
Accident Criteria for NTSB Investigation
The National Transportation Safety Board (NTSB) is responsible for investigating transportation accidents in the United States. The NTSB’s mission is to determine the cause of transportation accidents and make recommendations to prevent future accidents.
The NTSB investigates a wide range of transportation accidents, including:
- Aircraft accidents
- Railroad accidents
- Highway accidents
- Marine accidents
- Pipeline accidents
The NTSB does not investigate all transportation accidents. The NTSB typically investigates accidents that:
- Result in a fatality
- Result in serious injury
- Cause substantial property damage
- Involve a common carrier
- Could have significant implications for transportation safety
The NTSB’s investigations are typically conducted in three phases:
- Factual investigation: The NTSB gathers information about the accident, including weather conditions, mechanical failures, and human factors.
- Analysis: The NTSB analyzes the information gathered during the factual investigation to determine the cause of the accident.
- Recommendations: The NTSB makes recommendations to prevent future accidents based on the findings of the investigation.
The NTSB’s recommendations are not binding, but they are often adopted by transportation regulators and industry stakeholders.
Types of Accidents Investigated by the NTSB
The National Transportation Safety Board (NTSB) is responsible for investigating major transportation accidents in the United States. These accidents involve various modes of transportation, including:
- Aviation
- Highway
- Rail
- Pipeline
- Marine
Investigative Process
When an accident occurs, the NTSB deploys a team of investigators to the site. The team conducts a thorough investigation, which typically includes:
- Examining the accident scene
- Interviewing witnesses and survivors
- Collecting and analyzing evidence
- Recreating the accident sequence
- Determining the probable cause
Collaboration
The NTSB works closely with other agencies and organizations during its investigations. These include:
- Federal Aviation Administration (FAA)
- Federal Highway Administration (FHWA)
- Federal Railroad Administration (FRA)
- Pipeline and Hazardous Materials Safety Administration (PHMSA)
- National Oceanic and Atmospheric Administration (NOAA)
By collaborating with these agencies, the NTSB can obtain a comprehensive understanding of the accident and its causes.
| Type of Accident | Investigating Agency |
|---|---|
| Aviation | NTSB |
| Highway | NTSB and state or local police |
| Rail | NTSB and FRA |
| Pipeline | NTSB and PHMSA |
| Marine | NTSB and NOAA |
