Air Accidents Investigation Branch home


 AAIB investigations are conducted in accordance with Annex 13 to the ICAO Convention on International Civil Aviation, EU Regulation No 996/2010 and The Civil Aviation (Investigation of Air Accidents and Incidents) Regulations 1996.

The sole objective of the investigation of an accident or incident under these Regulations is the prevention of future accidents and incidents. It is not the purpose of such an investigation to apportion blame or liability.

Accordingly, it is inappropriate that AAIB reports should be used to assign fault or blame or determine liability, since neither the investigation nor the reporting process has been undertaken for that purpose.

Extracts from AAIB reports may be published without specific permission providing that the source is duly acknowledged, the material is reproduced accurately and it is not used in a derogatory manner or in a misleading context.

Formal reports: These are reports of Inspectors Investigations relating to specific accidents or serious incidents.

Bulletins: A monthly publication of accidents and serious incidents published on the second Thursday of the month.

Special Bulletins: Bulletins detailing the initial facts after a major accident.

Interim Reports:  Reports published at significant major investigation 'milestones' i.e. Safety Recommendations.

Annual Safety Reports (previously named AAIB Progress Reports): An annual publication containing information on the AAIB's activity, accident and incident statistics and Safety Recommendations and reponses.

Foreign Reports: Reports published by foreign accident investigation authorities.
