FAA vs NTSB: Who Investigates Aviation Accidents in the United States?

FAA vs. NTSB: Who Does What After an Aviation Accident?

When an aviation accident occurs in the United States, two federal agencies quickly become involved: the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA). Their names frequently appear together in early news reports, but the agencies serve different roles within the aviation safety system.

Understanding the distinction between these agencies helps journalists accurately explain how aviation accidents are investigated. In simple terms, the NTSB leads the accident investigation and determines probable cause, while the FAA regulates aviation and enforces safety rules.

Quick Reference: FAA vs. NTSB

What Happens Immediately After an Aviation Accident

The NTSB: Lead Accident Investigator

The National Transportation Safety Board (NTSB) is the federal agency responsible for investigating civil aviation accidents in the United States. When a major accident occurs, the NTSB assumes control of the investigation and directs the overall investigative process.

Investigators examine the aircraft wreckage, flight data recorders, cockpit voice recordings, maintenance history, operational procedures, air traffic control communications, and environmental conditions surrounding the accident.

The agency’s mission is to determine what happened, why it happened, and how similar accidents can be prevented in the future.

A detailed explanation of this process can be found in How the NTSB Investigates an Aircraft Accident.

The FAA: Aviation Regulator

The Federal Aviation Administration (FAA) serves as the United States’ primary aviation safety regulator. The FAA writes and enforces the regulations governing aircraft design, certification, maintenance, pilot licensing, and flight operations.

Following an accident, the FAA participates in the investigation by providing regulatory expertise and technical knowledge related to aircraft certification, maintenance compliance, and operational procedures.

If violations of federal aviation regulations are discovered during the investigation, the FAA may initiate regulatory or enforcement actions.

Typical Responsibilities During an Investigation

Other Participants in Aviation Investigations

Major aviation accident investigations often involve technical participation from aircraft manufacturers, airlines, maintenance providers, engine manufacturers, and labor organizations representing pilots or mechanics.

These participants assist investigators through the NTSB’s designated party participant system, which allows technical experts to provide specialized knowledge about the aircraft and systems involved.

The structure and limitations of this system are discussed in The NTSB Party Participant Process in Aviation Accident Investigations.

What the NTSB Does Not Do

Although the NTSB determines the probable cause of aviation accidents, the agency does not assign legal liability and does not award compensation to victims.

Questions involving responsibility for injuries, damages, or wrongful death are addressed separately in civil litigation.

The interaction between accident investigations and civil proceedings is discussed in NTSB Investigations & Civil Aviation Claims.

Why the Distinction Matters

Because the FAA and NTSB perform different functions, early reporting about aviation accidents sometimes conflates their roles. Statements made by the FAA typically concern regulatory oversight or operational issues, while statements issued by the NTSB relate to the progress of the accident investigation itself.

Recognizing this distinction helps journalists and observers accurately explain the investigative process and understand how aviation safety improvements emerge from accident findings.

Two Agencies, One Objective

Although the FAA and the NTSB serve different institutional roles, their work ultimately supports the same objective: improving aviation safety. The NTSB investigates accidents and identifies their causes, while the FAA regulates the aviation system and implements safety standards.

Together, these two agencies form the foundation of the United States aviation safety system.
