Under Section 5 of the Bharatiya Vayuyan Adhiniyam, 2024, the Bureau of Civil Aviation Security constituted under the erstwhile Aircraft Act, 1934 is:

Section 5(1) provides that the Bureau of Civil Aviation Security constituted under the Aircraft Act, 1934 shall be deemed to have been constituted under the new Act, continuing to be headed by an officer designated as the Director General of the Bureau of Civil Aviation Security, appointed by the Central Government by notification. Section 5(2) assigns the Bureau responsibility for regulatory and oversight functions relating to civil aviation security matters, while Section 5(3) vests the Bureau's administration in this Director General. This "deeming" continuity ensures a seamless institutional transition from the 1934 Act's framework to the new Adhiniyam without any regulatory vacuum in aviation security oversight.
