The HAL HPT-32 Deepak ("light" in Sanskrit) is an Indian prop-driven primary trainer manufactured by Hindustan Aeronautics Limited. The student and the instructor sit side-by-side. The aircraft can accommodate one passenger.
Operational history
The Deepak is used for primary training, observation, liaison and target towing.
Retro-fitting safety systems
- When it flies upside-down fuel flows from a collector tank in the fuselage and the inverted flight is limited to 1 min. Unlike the fears in some of the peoples minds that fuel stops in inverted flight, the above design does cater for the intended flying.
- Deepak has a theoretical glide ratio of 8.5:1, which practically is about 5:1.
It has been reported the IAF and HAL are looking into radical safety systems such as attaching 'ballistic activated parachute' to the aircraft to enable it to descend safely in the event of an engine failure. On May 16, 2010 the IAF gave clearance for a parachute recovery system to be fitted on the trainer. During an emergency the pilot can deploy the parachute by using a lever. With no other basic trainer available, the IAF envisions that the parachute system will make the training process safer in the future. It is learned that most of the qualification tests have been completed. Approval from the IAF is required for fleet integration.l.[2]
Accidents
An aircraft crashed in the outskirts of the city of Medak, Andhra Pradesh on July 31, 2009, killing both the pilots. The causes of the crash are being investigated.
In 17 Deepak crashes so far, 19 pilots have died.[3] The Comptroller and Auditor General (CAG) of India has been reported as saying the aircraft is "technologically outdated and beset by flight safety hazards" when discussing the grounding of the fleet in 2009[4]
