Who among the following is responsible for pre-flight anti-sabotage check of an aircraft ?

In the Indian aviation security framework, the responsibility for the pre-flight anti-sabotage check of an aircraft rests with the Airlines security. According to the guidelines issued by the Bureau of Civil Aviation Security (BCAS), while the Airport Security Group (ASG)—which is typically the Central Industrial Security Force (CISF)—is responsible for the overall security of the airport terminal, perimeter, and passenger frisking, the airline is specifically responsible for the security and integrity of its own aircraft. This check involves a detailed inspection of the cabin, toilets, galleys, and cargo holds to ensure no prohibited items or explosives have been planted. The BDDS (Bomb Detection and Disposal Squad) is a specialized unit called only when a suspicious object is found, and the flight crew is primarily responsible for safety and operational checks rather than formal security anti-sabotage protocols.
