Pakistan period

Aviation in India can be traced to the first commercial flight on 18 February 1911, and grew during the period between the First and Second World Wars. Some 103 airports, aerodrome, airfields and airstrips were built and operated by the Allied Air Forces in the part of present Bangladesh during the Second World War. These airfields were extensively used for conducting air operations during the Burma Campaign against the Axis powers. After the War, most of these facilities of the Royal Indian Air Force were left unused. After independence from British colonial rule and the partition of the subcontinent, the aviation infrastructure and facilities in what was then East Pakistan were inherited by the Pakistan Air Force.

After the Bangladesh Liberation War of 1971, a Department of Civil Aviation (DCA) was established^[1] Airports Development Agency was a limited company that was working before the Independence of Bangladesh since 1965 and worked as a contractor for the Department of Civil Aviation.^[1]

The Department of Civil Aviation and the Airports Development Agency were merged by the government of Bangladesh to create Civil Aviation Authority in 1982.^[1]

In 1985, the present Civil Aviation Authority of Bangladesh (CAAB) came into existence as a body corporate with full managerial power, both organisational and financial, vested with it vide Ordinance, 1985. This ordinance repealed Ordinance, 82, dissolved the previously constituted Civil Aviation Authority and transferring all its establishment, assets and liabilities to the new authority.^[1]
