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 often become involved quickly: 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 explain the post-accident process more accurately. In broad terms, the NTSB leads the accident investigation and issues probable-cause findings, while the FAA regulates aviation safety and may take regulatory or enforcement action where appropriate.

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 significant accident occurs, the NTSB generally assumes control of the investigation and directs the overall investigative process.

Investigators may examine the aircraft wreckage, recorded flight information, 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 may 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 regulations governing aircraft design, certification, maintenance, pilot licensing, and flight operations.

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

If the investigation reveals possible regulatory violations or broader safety concerns, the FAA may consider regulatory, administrative, or enforcement action.

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 may assist investigators through the NTSB’s designated party participant system, which allows qualified organizations to provide technical knowledge about the aircraft, operations, or systems involved.

The structure and limits of the investigative process are discussed further in How the NTSB Investigates an Aircraft Accident.

What the NTSB Does Not Do

Although the NTSB issues probable-cause findings in aviation accidents, the agency does not assign civil 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 often concern regulatory oversight, operational issues, or safety actions, while statements issued by the NTSB generally relate to the progress of the accident investigation and its findings.

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

Two Agencies, One Objective

Although the FAA and the NTSB serve different institutional roles, their work ultimately supports the same broader objective: improving aviation safety. The NTSB investigates accidents and issues findings and recommendations, while the FAA regulates the aviation system and implements safety rules.

Together, these two agencies form a central part of the United States aviation safety system.
