The Indian military has grounded their fleet of Russian SU-30 fighters after a crash involving a more advanced version:
For the second time this year, India has grounded its Su-30 fighters because one of the aircraft crashed. This time, the grounding of the 98 Su-30s in service is expected to last only a few days. Earlier this year, in May, its Su-30 fighters were grounded for a month after one of them appeared to develop engine problems and crashed. One of the pilots survived, but the parachute of the other failed to open. Four days before the Indian Su-30 went down, a Russian Su-35 also crashed because of engine problems. The Su-35 is an advanced version of the Su-30, and uses a similar engine. Earlier this year, Russia grounded all its MiG-29 fighters to check for structural problems, after one of them came apart in flight. All this is particularly upsetting to Indians, who had been assured by the Russians that the Su-30 was a modern (built to Western standards of reliability) aircraft. Such assurances were necessary because of earlier Indian experience with the MiG-21, and Russian aircraft in general. So far this year, India has lost twelve military aircraft, most of them of Russian design.
