Hindustan Aeronautics Limited (HAL), a Navratna Public Sector Company is a pioneer inAircraft Industry in South Asia (www.hal-india.com).
2. Transport Aircraft Division (TAD), is an AS 9100C, IS/ISO 9001:2008, IS/ISO 14001:2004certified division of HAL. HS 748aircraft was manufactured at TAD, Kanpur under licensefrom M/s BAe,UK. HS 748 aircraft is medium sized turbo prop aircraft. It is a 45-48 seat a/cwith takeoff weight 20,180kgs. Currently major overhaul of HS 748 aircraft is carried out atKanpur. HS 748 a/c is currently fitted with Rolls Royce Dart engines 536-2T(2040SHP) and533-2(1990SHP). Transport Aircraft Division, Kanpur is contemplating replacement of RollsRoyce Dart Engine with modern fuel efficient engines on HS 784 aircraft along with otherelectrical, avionics and structural upgradation .
3. Presently used Roils Royce Dart engine is a gas turbine engine designed to drive apropeller and to give a small amount of jet thrust. Main components of engine are twostage centrifugal compressor, 7 combustion chamber and 3 stage axial flow turbine. Thecompressor is directly coupled through a shaft to turbine and the propeller is driven by theturbine through a separate shaft and compound reduction gear box. This Dart engine hasSpecific fuel consumption of 0.767lbs/hr/shp which is quite high compared to same class ofmodern engines.

Further Rolls Royce Dart Engine mechanically drives Accessories Gear Box of Aircraft bydrive shaft assembly. Accessories Gear Box further drives following accessories:
Cabin super charger(for cabin pressurization). Tachometer. Alternator. Hydraulic pump. Generator.
Accessories mentioned above needs to be upgraded technically.
4. Currently there are 59 HS748 aircraft in service with our operators. Due to low utilizationrate (Average 350Hrs/Year) majority of aircraft have technical residual life around80,000Hrs. Owing to the good health of the airframe and considerable residual life,replacement of Rolls Royce Dart Engine with modern fuel efficient engines on these 59 HS784 aircraft is being planned.
