The HS-748 would prove to be one of the most successful postwar British aircraft produced, selling around the world to both national airlines and smaller operators alike who needed a rugged dependable aircraft. These characteristics would be taken to their limits within India which saw in the 748 just the aircraft it needed for both military and civil operations.

The career of the remaining HAL-748s with Indian Airlines appears to have drawn to a close following the creation of the government owned regional airline Vayudoot, which was tasked with flying in the inhospitable Northeast of the country. The eight remaining IAL HAL-748s joined the airline and served alongside F27s and Dornier 228s. Vayudoot was never profitable and was merged into Indian Airlines between 1993 and 1997. All the 748s were stored at Hyderabad during December 1993 and subsequently broken up. They had provided over 25 years of safe operations proving the validity of the thinking behind the development of the type.
Impressively despite the types relative unsuitability as a military transport aircraft (no ramp for example) even in 2014 around 60 of the Indian Air Force HAL-748s remained in service. Many of these airframes had low hours and Hindustan Aeronautics was even suggesting that they be upgraded for further service. As of 2016 this is still unresolved, though surely the purchase of C-27 Spartans or CASA C-295s makes much more sense. Nonetheless the HAL-748 has a unique place in the history of Indian aviation and for its time was a successful programme which was able to utilise the core strengths of the Avro 748 to the full.
