To search the NTSB Aviation Accident Data Base, enter your selection criteria into
one or more of the boxes on the search form. Some boxes (State, for example) contain
a list of choices from which you may select. For other boxes, enter the text to
- use % as a wildcard to search on any character combination
- use _ as a wildcard to search on any single letter
- text searches are not case-sensitive
- a match may "contain" the specified text and does not necessarily begin
- embedded spaces may be considered as part of the text to match
Some text boxes (aircraft make and model, for example) include an auto-complete
function that will display matching standardized values after typing the first three
characters of the aircraft make and/or model name.
See additional search tips below. To be selected, a record
must meet all of the criteria you have entered.
Select the display options you want to use and click on the [Submit Query] button.
When the search is completed, you will see the number of records found at the top
of the results table. Basic information about the matching records will be displayed,
and may be spread over multiple pages. The left-most column of the table or list
will contain links to accident synopses for most cases. The second column provides
a link to extended information in specially-formatted PDF reports. Links in these
columns are an indication of the type of information contained in the synopsis.
Where the link is "Preliminary", the synopsis is based on the preliminary
accident report and should be treated as preliminary information, subject to change.
Where the link is "Factual", the synopsis contains information
from the factual report. Where the link is "Probable Cause", the
synopsis contains information from the final report and includes the probable cause.
Synopses may not be available for dates before 1993, cases under revision, or accidents
and incidents where the NTSB did not have primary investigation responsibility.
A link to a full, extended narrative is available following the synopsis under "Factual"
or "Probable Cause" links selected from the first column.

Start and End Date Range
Use the Event Start Date and Event End Date fields to limit the search to the time
period between two dates. Clicking in either fieldwill bring up a calendar control.
Query start and end dates can be specified using the calendar control or by typing
the date. . To limit the search to one specific date, enter that date in both boxes.
You may also select accidents occurring in only one month. When used in conjunction
with the Event Start and Event End Date fields you can select records occurring
during the same month over several years.
You may type either the entire name or (preferably) only part of the name of a city
or a place (such as Grand Canyon). The location you seek may be coded as the name
of a nearby town or place; for example, Aliquippa rather than Pittsburgh. When looking
for accidents near a town that is close to a State border, you may need to search
for accidents in one State, then the other State.
State and Country
Each record in the NTSB data base contains codes identifying the State and Country
location of an event. There are codes for all of the States in the USA, some bodies
of water, US territories and possessions, foreign countries, a catch-all "other
foreign country", and "Unknown". (Only a limited number of foreign
accidents are included; see Foreign Investigations
for further information.) The default selection is "Anywhere", but you
may limit your search to records that contain only one of the specific codes.
All investigations in the online aviation accident database are defined as either
"Incident" and "Accident." An accident is defined as
"an occurrence associated with the operation of an aircraft which takes place
between the time any person boards the aircraft with the intention of flight and
all such persons have disembarked, and in which any person suffers death or serious
injury, or in which the aircraft receives substantial damage". An incident
is defined as "an occurrence other than an accident, associated with the operation
of an aircraft, which affects or could affect the safety of operations." The
Safety Board investigates only selected incidents, including them in the database
in the same form as accidents. Typically, incidents do not involve the level of
injury or damage characteristic of an accident.
You may use this field to limit the search to records matching the degree of severity
you select. All "accidents" in the online aviation accident database are
classified as either ""Non-Fatal" or "Fatal". (There is
no injury severity classification for "incidents".)
You may use this field to limit the search to records involving aircraft of one
of the categories listed. Note: some ultralights are listed as airplanes
in the database.
Selecting "All" will select records that involve manufactured and amateur
built aircraft. Selecting "Yes" will limit the selected records only to
those that involve amateur built aircraft.
Aircraft Make and Model
Enter text identification for make and/or model; order is not significant. After
typing three or more characters in the make and model fields, an auto-fill will
display matching standardized values. You may either select one of the standardized
values, or specify you own text identification. The query will search against both
the list of standardized make and model names, and the free text data entered for
each case. To be most inclusive, do not be overly restrictive in specification.
· Entering “donne” rather than selecting
a specific make or model name returns records involving aircraft manufactured by
McDonnell Douglas, as well as several variations of the correct spelling
· “Boeing”returns "Boeing 747"
as well as "Boeing B-747-200"
· [cessna] returns "Cessna 182A",
"Cessna 182E", and similar aircraft
If your results are unexpected, compare your character strings with the selected
records or try entering a partial name rather than selecting a specific make or
Enter all or part of the registration number. Include hyphens (or wildcard) when
appropriate. For example, searching for "HI6" and "HI-6" registration
numbers returns different results. A leading "N" for US-registered aircraft
is not necessary but can be used for differentiation.
You may use this field to limit the search to records matching the degree of aircraft
damage you select. Options include “Minor”, “Substantial”, and “Destroyed”. Refer
to Title 49 Code of Federal Regulations 830.2 for definitions of aircraft
Number of Engines and Engine Type
Use the Number of Engines and Engine Type fields to limit the selected records to
events involving aircraft with a specified number and/or type of engine(s). The
engine type field includes a dropdown box specify options such as “reciprocating”,
“turbo fan”, or “turbo prop.
Use this field to limit the selected records to specific types of revenue air carrier
operations, all revenue air carrier operations, or general aviation (which includes
non-revenue air carrier operations). Briefly stated, Part 121 applies to air carriers
operating large transport category aircraft. Part 135 applies to air carrier operations
of smaller aircraft. Part 129 refers to air carrier operations of foreign air carriers.
Purpose of Flight
For operations other than air carrier, use this field to specify the purpose of
flight. Examples include personal, instructional, or business flying. The list of
options was expanded in 2005 to include additional categories such as firefighting,
and parachute drop that were not used for cases that occurred during earlier years.
Use this field to specify scheduled or nonscheduled Part 135 and Part 121 air carrier
operations. Scheduled Part 121 includes most passenger airline operations, and Nonscheduled
Part 121 includes cargo operations in large aircraft. Scheduled Part 135 is commonly
referred to as "commuter", whereas Nonscheduled, or On-Demand Part 135
are sometimes referred to as "air taxi" or “charter” operations.
Use this field to narrow the selection to air carrier records that contain your
specific character string. To improve your chances of finding all records of interest,
do not be more restrictive than necessary; for example, do not enter “delta airlines”
when “delta” will suffice. The airline names are not presently standardized, so
entering a character string that contains only a portion of the airline name is
more likely to yield the record(s) you seek than would a character string that attempts
to make an exact match.
NTSB Accident Number
Each investigation is assigned a unique 10- or 11- character "accident number"
by the NTSB. It begins with the designator of the investigating office (for example,
LAX), followed by the two-digit fiscal year, followed by a code for the type of
investigation. The remainder of the string is usually a sequence number. Although
some offices have been consolidated over the years (e.g. SEA and LAX into WPR),
the location designator used at the time the case was initially created is still
You may use this field to limit the search to records matching the report status.
Briefly stated, Preliminary synopsis is based on the preliminary accident
report and should be treated as preliminary information, subject to change. Factual,
the synopsis contains information from the factual report. Probable Cause,
the synopsis contains information from the final report and includes the probable
Start and End Probable Cause Issue Date Range
Use the Probable Cause Issue Start Date and End Date fields to limit the cases completed
between two dates. Clicking on the box will bring up a calendar control. Query start
and end dates can be specified using the calendar control or by typing the date..
To limit the search to one specific date, enter that date in both boxes.
Airport Name and Airport Code
Use these fields to do text search for events occurring on or near a particular
airport. Enter text identification or a partial name for the airport name or code.
After typing three or more characters in the airport code field, an auto-fill will
display the matching airport code and name. The standardized code lookup includes
most airports in the United States. You may either select one of the standardized
values, or specify you own text identification.
Use this field to do a keyword search of the narrative text fields.

Use this field to limit the query based on the prevailing weather conditions at
the time of the event. Options include Visual Meteorological Condition (VMC) and
Instrument Meteorological Conditions (IMC).
Broad Phase of Flight
You can limit the query to only those event occurring during a particular phase
of flight. Most accident and incident events involve several notable events that
may occur during different phases of flight. This field limits the query based on
events occurring during the first accident phase.
Latitude and Longitude Search
Since 2002, NTSB records of accidents and incidents occurring in the United States
include Latitude and Longitude information. However, in some cases the latitude/longitude
coordinates are estimated from the nearest town or airport rather than the precise
location of the accident or incident site. After entering the latitude and longitude
of a point of interest, use the “within _miles” drop down to find cases within 25,
50, or 100 miles of that point. Values should be entered in a degrees.decimal-degrees
format (e.g. – 77.3778).
