We also provide assistance and expertise to international air accident investigations and organisations.
Our purpose is to improve aviation safety by determining the circumstances and causes of air accidents and serious incidents, and promoting action to prevent reoccurrence.
Who we are
AAIB has its origins in the Accidents Investigation Branch of the Royal Flying Corps, founded in 1915. We’re now an independent unit within the Department for Transport.
The Chief Inspector of Air Accidents reports directly to the Secretary of State for Transport on air safety matters.
There are 6 teams of inspectors, each led by a principal inspector. The teams are made up of operations inspectors, engineering inspectors and flight data recorder inspectors.
There’s more about the inspectors’ experience and their duties in our ‘Working for us’ section.
Our work includes:
responding quickly to air accidents and serious incidents
leading and managing the investigation team while ensuring their safety at the accident location
conducting thorough, independent, impartial and timely investigations into air accidents and serious incidents
producing reports that explain the circumstances and causes of accidents and serious incidents, without attributing blame
ensuring we follow the International Civil Aviation Organization Annex 13 and UK statutory obligations for the investigation of air accidents
providing assistance and expertise to international air accident investigations and organisations
improving aviation safety in general through education and sharing the lessons learnt from accident investigations
treating the survivors and relatives of air accident victims sympathetically, helping them understand what happened and what’s being done to prevent future accidents
