"The pilot ejected but died due to injuries sustained by him," defence spokesperson S D Goswami told PTI.
The MiG-21 ''Type-96'' aircraft was on a routine sortie and crashed near the airfield, which is about 15 kms from Bikaner city, he said.
This is the second crash of a MiG series fighter aircraft this year. On February 4, an IAF MiG-21 ''Bison'' fighter plane had crashed apparently due to an engine problem while on a routine sortie in Madhya Pradesh's Sheopur district but the pilot had ejected safely.
In 2010, a total of 10 IAF aircraft crashes took place including four MiG-27 and two MiG-21 planes.
