During 1986, the Indian Government constituted the Army's Aviation Corps; consequently, the majority of Chetaks previously operated by AOP Squadrons were transferred from the Indian Air Force to the Indian Army on 1 November 1986. The Air Force has continued to fly a force of armed Chetaks in the anti-tank role as well as for CASEVAC missions and general duties. During the 2010s, the Chetak is being gradually replaced by the newer HAL Dhruv in the armed forces. An option to re-engine the HAL Chetak with the Turbomeca TM 333-2B engine, which would better facilitate high-altitude operations in the Himalayas was considered, but ultimately not pursued.
