Accident Investigation Glossary
The following glossary is taken from ICAO's International Standards and Recommended Practices, Chapter I. Definitions
Accident. An occurence associated with the operation of an aircraft which takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, in which :
a) a person is fatally or seriously injured as a result of :
- being in the aircraft, or
- direct contact with any part of the aircraft, including parts which have become detached from the aircraft, or
- direct exposure to jet blast.
b) the aircraft sustains damage or structural failure which :
- adversely affects the structural strength, performance or flight characteristics of the aircraft, and
- would normally require major repair or replacement of the affected component.
except for engine failure or damage, when the damage is limited to the engine, its cowlings or accessories; or
for damage limited to propellers, wing tips, antennas, tires, brakes, fairings, small dents or puncture holes in the aircraft skin; or
c) the aircraft is missing or is completely inaccessible.
Note 1 - For statistical uniformity only, an injury resulting in death within thirty days of the date of the accident is classified as a fatal injury by ICAO.
Note 2 - An aircraft is considered to be missing when the official search has been terminated and the wreckage has not been located.

Causes. Actions, omissions, events, conditions, or a combination thereof, which led to the accident or incident.
Flight recorder. Any type of recorder installed in the aircraft for the purpose of complementing accident/incident investigation.
Incident. An occurence, other than an accident, associated with the operation of an aircraft which affects or could affect the safety of operation.
Note - The type of incidents which are of main interest to the ICAO for accident preventing studies are listed in the ICAO Accident/Incident Reporting Manual.
Investigation. A process conducted for the pupose of accident prevention which includes the gathering and analysis of information, the drawing of conclusions, including the determination of causes and, when appropriate, the making of safety recommendations.
Investigator-In-Charge. A person charged, on the basis of his or her qualifications, with the responsibility for the organization, conduct, and control of an investigation.
Note - Nothing in the above definition is intended to preclude the functions of an investigator-in-charge being assigned to a commission or other body.
Maximum mass. Maximum certificated take-off mass.
Operator. A person, organization or enterprise engaged in or offering to engage in aircraft operation.
Preliminary Report. The communication used for the prompt dissemination of data obtained during the early stages of the investigation.
Safety recommendation. A proposal of the accident investigation authority of the State conducting the investigation, based on information derived from the investigation, made with the intention of preventing accidents or incidents.
Serious incident. An incident involving circumstances indicating that an accident nearly occured.
Note 1 - The difference between an accident and a serious incident lies only in the result.
Note 2 - Examples of serious incident can be found in Attachment D of Annex 13 and in the ICAO Accident/Incident Reporting Manual (Doc 9156).
