Overview
NTSB accident investigations often require 12 to 24 months
to complete. This is due to the complexity of the factual
information that must be collected and the importance
of conducting a comprehensive analysis to determine its
relevance to the cause of the accident.
During the investigation, the following reports are published on
the NTSB website:
• The Preliminary Report provides a synopsis of factual
information collected during the on-scene phase of the
investigation. This report is typically available within a few
weeks after the accident.
• The Accident Docket includes relevant information
collected during the investigation and considered in the
development of reports or briefs and determination of the
probable cause. Examples of docket items may include
accident photographs, maintenance records, and witness
statements. The docket is released publicly when most
of the relevant factual information is collected for the
investigation or at its conclusion.
• The Final Report provides a summary of relevant factual
information, analysis, ndings, probable cause, and
safety recommendations issued or reiterated as a result
of the investigation; or an Accident Brief that consists
of a short accident narrative, probable cause, and safety
recommendations. Briefs are normally limited to factual
information but may contain analysis.
The report or brief replaces the preliminary report and is
typically available 12 to 24 months following the accident.
The NTSB may issue Safety Recommendations at any time
during the investigation to address a particular issue and
specify how to correct the situation. Recommendations are
issued to relevant stakeholders best able to address the issue.
The NTSB will work with relevant stakeholders to identify
safety issues that can be promptly corrected through
suggested solutions. These solutions can be implemented
without having to issue formal safety recommendations.
The NTSB may also issue Safety Alerts designed to enhance
the understanding of safety issues and offer suggested
actions to mitigate them.
Party System
The NTSB has the authority to designate organizations,
corporations, or agencies as parties to the investigation.
Only representatives who can provide technical or
specialized expertise are permitted to serve as party
members and report directly to the NTSB.
Parties are permitted to assist the NTSB with the collection
of factual information but cannot participate in its analysis.
The NTSB is solely responsible for analyzing factual
information to determine its relevance to the probable cause
of the accident.
Staying Informed
Survivors, families, and friends can contact the TDA Division
directly regarding an NTSB investigation and to learn more
about available resources. TDA Specialists work closely with
the IIC to address questions regarding an investigation.
