Since 1979, the Accident Investigation Board (AIB) has conducted independent and impartial investigations of accidents and serious incidents.

Aa safety investigation of an accident in 1972 near Dubai to a Danish registered aircraft led to the establishment of an independent and impartial commission. An safety investigation team from the supervisory authority conducted the investigation of the accident near Dubai.

At the publication of the final report, new factors were revealed, which had not been investigated. These factors related to the role and area of responsibility of the supervisory authority.

On the 1st of January 1979, an independent and impartial commission named the Aircraft Accident Investigation Board (AAIB) was established. The AAIB existed until June 2004. In June 2004, a new organisation was established conducting both aviation and railway investigations. The new organisation was named the Accident Investigation Board - Aviation and Railway. The Accident Investigation Board or the AIB - in everyday speech .
