The Hindustan Aeronautics Ltd (HAL) HTT-34 was the turbo-prop version of the HAL HPT-32 Deepak. As such, it visited European airshows to atrract sales in 1984 and 1985. Without success, even the Indian armed forces did not order the type. Fortunately, the single prototype built has been saved and is currently on display at the HAL Technical Training Institute at Suranjan Das Road, Reddypalya, Jyothi Nagar, Bangalore.
