An occurrence associated with the operation of an aircraft which, in the case of a manned aircraft, takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time as it comes to rest at the end of the flight and the primary propulsion system is shut down, 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, 

except when the injuries are from natural causes, self-inflicted or inflicted by other persons, or when the injuries are to stowaways hiding outside the areas normally available to the passengers and crew; or 

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. 

Incident 

An occurrence, other than an accident, associated with the operation of an aircraft which affects or could affect the safety of operation. 

Note: The types of incidents which are of main interest to the International Civil Aviation Organization for accident prevention studies are listed in Attachment C to Annex 13. 

Serious Incident  

An incident involving circumstances indicating that there was a high probability of an accident and associated with the operation of an aircraft which, in the case of a manned aircraft, takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time as it comes to rest at the end of the flight and the primary propulsion system is shut down. 

Primary sources: Accident Investigation Boards, CAA’s, ICAO  

When primary sources are not (yet) available we use aviation industry and (social) media reports. 

A Confidence Rating is applied to each accident, showing the level of validation of the data for that occurrence. 

The ASN database contains all known airliner and corporate jet hull-loss occurrences. An ‘airliner’ being defined as an aircraft model certified to be able to carry 14+ passengers. 

Additionally, the ASN database contains known all airliner Accidents (ICAO Annex 13 definition) since 2017. 

Yes. If an event meets the ICAO definition of accident it is included in the database.   

Yes. If an event meets the ICAO definition of accident it is included in the database.

Yes, if an event meets the ICAO definition of accident it is included in the database. 

Yes, you can add accidents and incidents to the ASN WikiBase yourself! Or you can correct or update existing accidents. You can add any aviation accident or incident you like -- general aviation, military, helicopters, etc. -- as long as the event is not already covered in the main ASN Safety Database.
