The HAL HPT-32 Deepak is IAF's basic flight training aircraft for cadets.[179] The HPT-32 was grounded in July 2009 following a crash that killed two senior flight instructors,[180] but was revived in May 2010[180] and is to be fitted with a parachute recovery system (PRS) to enhance survivability during an emergency in the air and to bring the trainer down safely.[180] The HPT-32 is to be phased out soon.[180] The HPT 32 has been replaced by Pilatus, a Swiss aircraft.
