The Aircraft Accident Investigation Bureau (AAIB) is a specialized government agency found in several countries, including India, Malaysia, Myanmar, and the United Kingdom, responsible for investigating civil aviation accidents and serious incidents. Its primary mission is to enhance aviation safety by determining the causes of accidents, identifying contributing factors, and issuing safety recommendations to prevent future occurrences. The AAIB operates independently from regulatory and judicial authorities, ensuring impartiality and adherence to international standards set by the International Civil Aviation Organization (ICAO), particularly Annex 13 of the Chicago Convention.
Historically, the need for independent accident investigation bodies emerged to separate safety oversight from regulatory functions, a shift that gained momentum globally after major aviation disasters. For example, India established its AAIB in 2012, following international best practices, and later strengthened its mandate through amendments in 2017 and 2021. Similarly, Malaysia’s AAIB was created in 2011, while the UK’s Air Accidents Investigation Branch (AAIB) has a long-standing reputation for operational independence within the Department for Transport.
Key achievements of AAIBs include the publication of comprehensive investigation reports, the implementation of critical safety recommendations, and active participation in international investigations involving national aircraft. These bureaus have played a pivotal role in improving aviation safety protocols, influencing regulatory changes, and fostering global cooperation in accident prevention.
Today, AAIBs are recognized for their rigorous investigative processes, immediate access to evidence, and commitment to transparency. Their work not only safeguards lives but also supports the aviation industry’s technological advancement and operational excellence, making them essential pillars in the global aviation ecosystem.
