The HAL HPT-32 Deepak (Template:Lit) is an Indian prop-driven primary trainer manufactured by Hindustan Aeronautics Limited and are used as a basic trainer aircraft by the Indian Air Force and the Indian Navy. It has two seats in side-by-side configuration. It's configuration is low-wing, monoplane, single-engine aircraft designed primarily for the training of pilots in basic aerobatics, navigation, and other flying skills. The HPT-32 is equipped with a turboprop engine, offering good fuel efficiency and handling characteristics for new pilots.Template:Fact
However, it faced several challenges during its service. One of the major drawbacks was issues with the engine, leading to several accidents. As a result, the aircraft's service life was cut short, and it was gradually phased out in favor of more modern trainers, such as the HAL HTT-40.Template:Fact
Operational history
The Deepak is used for primary training, observation, liaison and target towing.Template:Fact
When it flies upside-down fuel flows from a collector tank in the fuselage and the inverted flight is limited to 1 min. Deepak has a theoretical glide ratio of 8.5:1. The IAF and HAL are looking into new safety systems such as Ballistic Recovery Systems to enable it to descend safely in the event of an engine failure. On 16 May 2010 the IAF cleared the installation of a parachute recovery system.[1] The HPT-32 aircraft has been replaced by the Pilatus PC-7 Mk II in the IAF, as its workhorse as a Basic Trainer Aircraft (BTA) in 2013.
Accidents
In 17 Deepak crashes so far, 19 pilots have died.[2] The Comptroller and Auditor General (CAG) of India has been reported as saying the aircraft is "technologically outdated and beset by flight safety hazards" when discussing the grounding of the fleet in 2009.[3] HAL HTT-40 is going replace HAL HPT-32 Deepak as primary trainer.[4]
