A Sukhoi-30 jet with two Air Force pilots on board went missing this morning around 11.30 am near Tezpur in Assam, while on routine sortie near China border.
The plane took off around 9:30 am and went missing near Doulasang area of Arunachal Pradesh, which is a border area adjoining China. The last contact was made at 11:30 am when the aircraft was nearly 60 km north of Tezpur in Assam.
The Tezpur Air Force station is located 172 km from the China border.
A search is on for the aircraft, said Sonitpur district Deputy Commissioner Manoj Kumar Deka.
The Sukhoi Su-30 is a Russian-made, twin-engine fighter meant for all-weather, air-to-air and air-to-surface missions. The first of the Su-30 planes were inducted by the IAF in the late 1990s.
Since their induction, six crashes have taken place. An inquiry into the plane accidents has primarily indicated technical failure as their cause.
In March this year, a Sukhoi-30 aircraft had crashed near an air base in Rajasthan's Barmer. Both pilots had ejected to safety.
