The plane is the same type that the Indian president flew in last month
The Indian Air Force (IAF) has grounded its entire fleet of Sukhoi fighter jets after one crashed during a routine training exercise in Rajasthan state.
All 100 such planes have been grounded as the IAF carries out "precautionary checks" following the crash.
Two crew members managed to eject from the Russian-designed Sukhoi-30MKI just before the crash on Monday.
Last month Indian President Pratibha Patil rode in a Sukhoi jet, becoming the first Indian woman to do so.
Monday's crash was the second such incident involving a Sukhoi fighter jet this year.
The air force is believed to have sought assistance from Russia for this investigation, the Times of India reported.
